MileagePlus X

I have been using the MileagePlus app for years. What I usually do is anytime I’m going to purchase anything I double check and see if the vendor is on the app. If I was going to spend money anyway buying from that vendor, I always go through the app and get miles for it, no matter how small the amount, my miles have been adding up. I think this is a great app if you are like me and travel occasionally, but do a lot of shopping and there are a lot of different vendors as options so anyone is bound to be able to use lots of them. I have all my payment info and I have never had a security issue with this app, and I’m very happy that I have never had an issue using any of the gift cards purchased to make payments anywhere that I go shopping. this is the best mileage earning app, and I think it puts United at the forefront of this type of service.

Previously app users were able to search by location, or even search by an expanded Map View for merchants and particularly MileagePlus Dining program restaurants outside of one’s immediate/home territory. This was a very useful integral feature to expand one’s search beyond your immediate area, which of course is necessary for selecting MileagePlus Dining restaurants when planning ahead for travel, while on road trips or when visiting locations outside of your immediate area. In recent updates to the Mileage Plus-X app, this functionality has been lost. I even tried turning “location” off on my device, in hopes that it would show ALL options on an expanded map view or show merchants/restaurants in the current expanding map view as I moved it to areas I’m interested in seeing options in, as it previous did… but it no longer does so. It now defaults to the same “Nearby” options based on current location, which when home, users are generally already familiar with. I don’t need an app to help “discover” businesses I’m already familiar with. What WAS formerly helpful was finding options in areas I’m LESS familiar with. Due to the LOSS of this feature, my use of MileagePlus Dining restaurants has significantly declined.

I like the app purely for the fact that I can earn miles for everyday purchases. The customer service on the other hand is pretty bad. I had an issue once where I purchased 1 gift card and they charged me for 2, it took them a week to respond to my initial email, then they tried to tell me I actually purchased 2 gift cards for the same amount. Like why would I do that? 🤦🏻‍♀️ Then most recently my app had a major glitch when I attempted to purchase a gift card it kept telling me that the app was not able to complete my purchase and my transaction was declined. For every establishment, not just 1. I emailed them as the error message directed, it took them 4 days to respond to my initial email, but they didn’t respond with anything useful, just a snip of my request being escalated but at the bottom it said to attach any useful evidence. So I responded with a screen shot of the error message. And still a week later no response. This customer service is not a good look for United.

I’ve earned over 50,000 miles on this app since downloading in 2022! I live in a city so I ALWAYS buy my uber/lyft/Starbucks/DoorDash, etc.. gift cards here to earn miles and then load them to those apps to pay. For bigger purchases I make shopping online i.e. ordering contacts & fashion sprees, I start through the shopping tile on this app and earn miles on my final basket total. My 3 month supply of contacts earned me 1,400 miles last month, easy win!! I also find this app a great way to learn about promotions going on with the airline programs like cruises sweepstakes and earning miles on Mother’s Day Flowers through FTD. The dining program shows me nearby restaurants where I can earn miles on enrolled cards and even sends me push notifications the moment I pay my bill, still at the table, pretty cool. If you fly United and you value their miles, this app really just makes sense.

I was using MPX for a while with no issues. As of late, I have had more declined transactions than ever. Maybe 1 in 40 will go through. I sent in support requests and am continually told it will not work outside of the United States. I am in New Jersey! I followed up again and was told that I need to delete all of my cards, delete the app, re-add my cards on United’s site, and then reinstall the app. Guess what! That didn’t work either. So while earning miles is a great idea and perk, they don’t want my money because they have rejected most of my transactions.

*minor update to down gauge my rating: App seems to crash when trying to buy another gift card after awhile then forces you to relogin with security questions again this only recently started* So I’ve had this app since the conception as I was one of the first group united invited to try. The format was simple and easy. Now that they have added extras and combined programs, it’s a little too complicated. Also keeps signing me out every 2 hours and gets annoying to try to relogin. Would recommend it as you still earn extra United Mileage miles but make purchases that u need. I’ve already made over 40k extra miles this year alone, 55k last year so well worth it

I love the miles plus program from United! I wish I would have discovered this a few years ago when I first started flying because it makes getting a *free* flight so much easier to achieve! In the last two weeks alone I probably have gotten close to 2,000 free miles just by shopping & dining at places that I was already going to! Instead of my buying miles to put towards a future flight I’m earning them with my everyday purchases & that to me is so worthwhile! Thank you United for creating this program to help me fund my travel plans!

I tried to purchase a $25 gift card to Starbucks. I received an email saying there was an error and I would be refunded within 5 days. I’ve purchased many cards and had never seen that email. So I tried again with the same result. I had 2 x $25 charges pending. 3 days later I see the first charge post. So I call United mileage plus program and and am given a different number. So I call that number and they are closed on the weekend. I understand things happen but there doesn’t seem to be any recourse. So now I will have to spend more time try to fix their error with them or with my bank reversing the charges. It’s frustrating because everything is through the app and immediate except when they screw up, then I have to call someone during business hours. I will try to call them on Monday.

Been using this app for years but now suddenly it keeps giving me an error saying transaction is declined. My credit card has no issues so it has to be the app. Checked reviews here and seems the same issue is happening to many others since last year!! Wow. Been contacting customer service through email but like other reviewers said, they first give you the copy and paste answer that this app can’t be used outside the US. I tell them I’m using it in the US and they say they’ll look into the issue but it’s been days. If the same issue is happening to others then they must know what the cause is? Why aren’t they preventing this issue from happening? Very frustrating.

I’ve been using this app since I joined the program. I love the fact that it allows me to boost my mileage balance by purchasing e-gift cards which are also very secure to shop. However, this year I have experienced the inconvenience of having the transaction declined for no apparent reason. It happens this summer and this weekend. I tried again today to find the same issue. I’ve deleted and reinstalled the app hoping that would fix the problem. I have also powered off my phone, but the same issue keeps coming up. I have contacted United by using the email they provided. I hope to be able to obtain an answer soon. Needless to say, this issue is frustrating as it keeps happening.

Using this app to purchase gift cards and check what merchants offer mileages, but do not use this app to connect to the merchants’ app directly for purchasing. When you use mileage plus x app to connect to another app for purchasing, most likely you will not get the mileages. This had happened to me too many times. When I emailed the unitedplus shopping, they told me I had to contact united. Then united kicked the ball right back to unitedplus shopping… well, bad enough to not get tracked properly, now neither united or unitedplus shopping know what they re doing. So I basically lost the bonus/extra mileages that I was supposed to get.

I’ve run into so many issues trying to make purchases through this app because it does not give you the option anywhere to change or update your billing address once you add it. You also can’t change or remove credit cards in your acc, it only allows you to add new ones but even then you can’t update your address from a previous one. Such a headache and I have missed out on trying to purchase various things because of the lack of accessibility on this app.

Today I tried to purchase a gift card and kept being told that it was denied, the credit card company told me that they denied nothing and that that no charges were made today. It also tells me to revalidate my mileage plus account. Customer service told me that they will have to turn it over to the development team and I will have to wait 7-10 business days. That’s one way to slow down my ability to earn more miles.

I tried shopping online for MilePlay. The first shop I purchased from didn’t have my order in their system. They refunded the charge I had to pay out of pocket without the additionally promised miles that would go toward MilePlay. I tried again with Shop Online at another shop. This time I received the item I purchased, but it’s been over 2 weeks (the max amount of time United said it would take to post miles) and still no miles accredited to my account. It’s also very unclear which phone number I should use to contact customer service for these ShopOnline transaction and MilePlay issues. E-gift cards doesn’t update the balance once part of it is used, which is misleading if I ever want to use up the rest of my e-gift card balance. UnitedDine was actually okay. Nothing went wrong there. Overall, seems like their system still needs to do a lot of work on customer service/support. Not worth the hassle to participate until they figure out how to collaborate with their affiliates and partners.

Used to be a big fan of this app though I seldom remembered to use it. I did try to use it recently and my credit card was charged twice but the transaction failed both times so the retailer didn’t get paid and I had to use a different form of payment. I expected the pending charges ($220 twice) would vanish from my Amex but, no, they became regular charges to my account. I then received emails from United promising refunds in about five business days, no idea why it takes that long, maybe they need the cash. That was twelve days ago and no refunds as yet. Makes no sense. Why charge me if you know the transaction has failed? Why take so long to process a refund that should be automatic? Have no confidence in this app going forward. Be warned!!

I was paying for a gift card and selected a credit card as my payment option. Upon purchasing the gift card and going through the verification I setup with 2-factor authentication, the system charged me miles instead of on my credit card as I previously selected. Due to the error, I reached out to customer service and “due to their no refund policy” nothing could be done. It’s extremely disappointing that nothing can be done when the the error lies solely on their end and instead of getting any type of human reaction or getting someone to look into the issue, they just can’t/won’t do anything about it.

For the last year and a half the app worked just fine. The last 2 months I have had issues. I get an error saying that my transactions are being declined when purchasing gift cards and to contact a service agent through a specific e-mail. I e-mailed this e-mail with my issue. I got 2 responses to fix the problem. The problem was not fixed by doing what they told me to do. I notified the it didn’t work, but no responses. I have since lost out on at least 1000 miles since this issue arose. I know it’s not my credit or debit cards declining the transactions because my banks have said so and I get e-mails that I’m getting miles on dining partners when I use my cards at dining partners. This has left a really bad taste in my mouth with United.

I have enjoyed using mileage plus and first look to it for many purchases. I have to say the system does have periods of time in which is does not work, will mistakenly give me the message I have exceeded my “Daily Spend limit” or “transaction failed”. Upon speaking with Mileage plus “Agents” I have gotten multiple variations on what the “maximum daily spend limit” is. I will continue to use given the benefits it provides for reduced travel costs in using the miles.

I love this app. It is so easy to use. The saddest is sometimes There are so many participating stores I forget to use it. The other problem is my mobile carrier so sometimes I’m in line a little longer then I would like. I dislike taking customer’s time behind me but the extra mileage makes it worth it. It isn’t an app issue either. Like I said I really like this app it helps add miles so easily.

I liked the app for earning miles, but be extremely careful when selecting payment method. I wanted to pay for a $29 restaurant bill using my United credit card. Didn’t have my reading glasses and accidentally clicked on the option to pay with United miles. 4,675 miles. When I realized my mistake I paid the bill with a different credit card assuming it would be simple to get a refund. No sympathy from United. NO REFUNDS. They are likely happy to see a customer burn their points at a such a low value. I am out significantly more points than I ever earned with the app and I have a non-refundable gift card that I am unlikely to use. Not sure if I will ever use the app again.

The app is absolutely worthless. I spend more time tracking my purchases and videoing my screen just to prove that I actually purchased items through the app than the actual value of points received. The points are either not posted or the eligible purchase amount is incorrect. I was monitoring the points received almost daily. I have to upload multiple receipts and evidence to prove the purchases because the app does not track or tracks incorrectly. Even with evidence the United customer support will try to claim that they have no record that purchases were made using the app. The app is exhausting. I’ve lost trust in the integrity of the app and I’m removing it.

While I am very satisfied with the app itself as long as there are no problems, contacting customer service has become a real pain. In the past (years ago) it worked well but now it takes months to receive a response and then they don’t even seem to have read my complain properly. I am still waiting for a refund for a faulty gift card from spafinder365. It might be that you are under staffed or your staff isn’t trained well. I recommend to do something about it. Respectfully Christian

I have been continually getting a “Transaction declined” error when I try to purchase gift cards. I emailed the technical support last week and had not heard back, so I called several different support numbers and kept getting bounced around. Finally, I got in touch with someone who couldn’t help me, but told me the department that handles app issues is a month behind in responding to requests. I asked if I could at least take advantage of the bonus mileage deals on the app after they expire since I don’t have access to the program. Nope, they can’t do that either. Don’t bother with this app, or United Mileage Plus.

I love UA and use my chase card all the time to shop MP shopping, so thought I’d try the MP X app....it’s seems easy and works fine, but my miles never seem to get to me! I’ve done everything correct as I’m familiar with the process, but the miles are either “pending” for months.....or I switched colors on a product, and it was denied, then I got the points, then denied again! I’ve emailed and filled out the proper forms and haven’t seen my miles or received any help or information on what’s happening. I wished it worked as well as MP shopping!

I used the app to buy a gift card to pay for my purchase at Home Depot in LA…after shopping for two hours and scanning over 50 items I got my total and entered it in the app. The cashier then says they do not accept gift cards from 3rd party apps and refused to accept my payment. Management was called and confirmed. I then tried to use it in self checkout and was stopped by management who accused me of committing fraud for trying to use the certificate I paid almost 500$ for. When I explained this and the fact I took my business elsewhere to support at UnitedX they refused to refund the charge and told me I can try using it online…DELETING THE APP

Absolute scam. Won’t let me log in. Using same credentials as the website and keeps getting an error. Can’t book anything through the website either. Took my points and credit card info. Charged my card but never sent a confirmation and no booking showing in my account. Tried 3 different phone numbers. Out of 3 was only able to talk to a person once who couldn’t help me and gave me a bad number where I couldn’t actually speak to anyone. Now I’m going to have to rebook my travel and file fraud on my card which I’ll be canceling since you can’t actually use any points you accrue.

I am not able to buy any gift cards, all transactions declined. I contacted the support over the course of two months now, they totally stopped replying. I have been told I need to be in US, I were all the times transaction declined, and location services were on all the times. On top, in order to not to be declined again, you need to wait at least 2 weeks and try again, I am told, which did not work either. To me it looks like they are total scam, whey are marketing the united bonuses and when you want to use them, no way. I am filing a complaint, as it looks like they are making fun of us

I enjoy the app and look forward to seeing what stores have additional miles daily. A suggestion for improvement would be for consumers to suggest stores. I still haven’t been able to access United dining. Not sure if there is something wrong with the link to their site but I cannot get in. This has affected my opportunity for bonus miles. Get this fixed and Id be happy to give you 5 stars.

The app is convenient to purchase gift cards until something goes wrong. When there is an error or fraud in your account the app directs you to an email address that is incredibly un responsive. I’ve used the app regularly and made thousands of dollars in purchases over the last few years. When you use something this much issues can be expected, but the fact it can take a week to receive a return correspondence from an agent in this day in age for a fraud issue, is ridiculous. The only reason continue to use this app is because it’s the only one like it.

It’s great earning the miles but they advertise being able to buy gift cards for bonus miles then block the account. I purchased my first gift card no issues at all. I went to buy another and the transaction will not go through. It’s been like this for ever a week now. I’ve emailed support multiple times and no response.

The app worked fine until every transaction I try to make now gets declined. Just as everyone else says, I try contacting them just to have no response for days. Certainly very frustrating that they have had this issue for a while now and nobody seems to care to look into it or fix the problem.

I made a purchase of $55 with the app generating a gift card while standing in the check out line. I chose my explorer credit card for payment but then I was directed to another screen and unknowingly to me it made the purchase with miles instead. And worst of all it cost over 8100 miles!!! I am hoping this can be reversed. The first screen did not finish the transaction with my credit card that I chose in the first place. I was in a hurry and I never even realized what happened till an email was sent to me with the summary, too easy to get confused or the app is just not functioning.

I have use this app for several years and up until a few weeks ago it worked perfectly. I really enjoyed using it and getting the extra miles because flying with United and star alliance is what I really enjoy doing when I go on vacation. However I have sent several emails and I’ve even called United and their website division about this, and I have yet to hear back from anyone. Every one of my transactions is declined. I don’t know if this app is no longer working but they would be best suited for its customers if they could correct this error.

Been trying to get this to work with no sucess for over a year now. No one seems to have any answers on how to fix it tried to uninstall and reinstall and deleted card and reentered card info to no avail. Surely someone can tell me how to get it working and how I can also do purchases from their website. Unfortunately it has cost me tons of mileage plus points by not being able to use it. Help please Roger Pennington Update thank goodness finally someone was able to get back with me and get it working again. In March of 2022. But it still cost me huge amounts of mileage plus points that I wasn't able to get while it wasn't working.

With this latest update the app doesn't work. It declines all of my transactions on all of my cards. I can’t get ahold of customer service, the only contact info is an email and the automated response you get says they will contact you in 7-10 days. It’s been 12 days and no response with multiple emails into them. This is an AWFUL way to run an app. I’ve tried the usual, deleted the app and reinstalled, deleted my cards and readers.... all to no avail. Come on guys, get with it. Have an actual phone line to call in to get actual help when your app doesn’t work.

I will give one star until the issue can be fixed. This has been going on for several months. My valid credits are identified as expired even though my cards are not. I have deleted app, reinstalled, deleted card, updated!! Basically I have tried everything. The app still lists my unexpired credit cards as expired!! How can you make the card that will expire in 2027 expire now !! I have contacted for the help. They said they would contact development team. I don’t know why this becomes an issue. Please fix it before I permanently delete it…thank you ..

I love this app. It allows you to get extra miles every time you purchase at one of the participating stores. One issue that needs to be corrected is redeeming a purchase. After you’ve used it it will not allow you to hit Mark redeemed until you close the app and then reopen it. Once they fix that, I don’t see any other issues with it.

I tried to purchase a gift card and the transaction kept getting declined for no apparent reason. I then tried to send the program admins an email through the app and received an automated response that they would review the email ad get back to me in 7-10 business days! Really??? 7-10 days? I can write a letter to the DMV, mail it and get a snail mail response faster than that Update: the customer service people did get back to me- a month later! And even then, it was to ask me to jump through a bunch of hoops, not to actually fix the problem. Save your time…

We're trying to earn enough miles for a bucket list trip and using the e-gift cards is earning us exponentially more than we are in day-to-day purchases. The learning curve can be tricky, but once you understand how it works, you'll find yourself using it for everything. Dog food and pet supplies alone will get us to our goal in no time.

Who doesn’t love earning miles while dining out at places you’re already visiting?! This app is handy dandy. One think I’d like to suggest (since I can’t write the developers directly) is that using the map search feature, it doesn’t show more than 10 miles away with additional restaurants outside of the nearby vicinity.

Even if you don’t fly often, it’s easy to earn miles. I once flew first class round trip from Houston to Maui for $25, which was airport fees only. I earn many miles dining, shopping at places like Walmart, and of course Starbucks. And flying is easier with this app. Highly recommend! Member for over 30 years.

This is a fantastic program for earning more miles, and I especially want to call out their great customer service. I ended up with a very difficult situation and although it took some time to resolve, the MileageX team persisted and found a solution. Thank you! 🙏🏼

Terrible customer service….by email only, at THEIR LEISURE. And they don’t work hard to resolve issues, either. For the second time, I am inexplicably having all e gift card transactions declined, no matter what card or merchant I select, despite all these having worked the day before. I tried uninstalling and reinstalling the app, powering on and off, switching devices, and everything else you can think of Wrote them and no answer, because they make SURE you cannot call! On United’s website, Mileage Shopping still works fine with all the same cards and merchants, so IT’S THE APP! Has happened before, as mentioned.

Not sure what is the basis but gets declined after one successful transaction to create an e-gift certificate. I use the app to pay wherever i can use the gift certificate option. But after one successful transaction every other gets declined. No help from email contact address. Won’t explain the reasons.

This app is a bit on the slower side especially during the payment process but it still takes less than a minute. The best part is how easy it is to shop and get extra points at places that you will normally shop anyways.

This app is great when it works. It gives you a quick way to rack up miles when purchasing eGift cards. However… and this is the caveat… every once in a while, the app will decline your purchases. It’s not your credit card’s problem, it’s the app’s unreliability. Lately, I have been experiencing this issue more often. I’ve lost thousands of miles in missed opportunities. Customer service is non-existent. They never bother to reply to issues reported.

For more than a month I keep trying to buy gift cards and it does not work, keeps “processing” or “transaction denied”. Credit card companies confirmed nothing was denied. Followed the contact procedure by email and no answer or bug fix. Lost the opportunity to make many miles. The prior review is from September with the same issue. Can I trust that this is just a bug?

The concept is great. I can earn miles even when not traveling. There are glitches with the app, though. The search function is frustrating. Sometimes you can not close the search window after conducting a search. I have to restart the app entirely or start entering random characters then redoing a “dummy” search in order to escape the window. It isn’t user friendly at all in that regard.

I cannot express how frustrated I got after wasting probably more than 5hrs on this app without being able to reach a real human customer service agent. This app DOES NOR WORK!! I have tried credit cards from both the US and other countries and all of them got declined ( my card works perfectly fine at other stores and websites). They don’t even try to solve this problem since there seems to be no customer service agent taking care of this terrible situation - all they allow you to do is to write a stupid email that no one ever replies

Fix your app…whatever updated you did is now forcing me to re enter my MP number/pw, and then answer my security questions (all 3) each time regardless if I saved my browser. I shouldn’t have to do this on a/my mobile device. If this is for “security reasons” it’s not well thought out because if I lose my phone I have much bigger issues on hand than MP purchases. Just force a reauth with Biometric on the authentication into the App and not on purchases
