1. 5/5Great for earning miles with your regular purchases

   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.

2. 1/5Hopeless

   Spent way too much time last night trying to purchase e gift cards for the holidays from merchants in the Mileage Plus X system. The major problem seemed to be its inability to process credit card payments. First it suggested I use my Mileage Plus credit card from Chase, which I tried. Then it rejected that credit card (no problems noted by Chase). Next I tried to enter another Chase credit card, but even when the form was filled in completely, there was no way to accept it and move forward. Also tried another brand credit card unsuccessfully. Later, I purchased the gift cards using one of the same credit cards directly on line with the same merchants but totally outside the app. The app also was annoying in demanding access to my location. As I was trying to make an on line purchase, I resisted this. Yet, I reluctantly tried to purchase with location granted, and it told me there were no stores in my vicinity. (Dah, I was traveling outside the US.) I continued to the e-gift card selection at my desired merchants, only to run into the same credit card stumbling block. My impression is that most people will use the app for on line purchases, not at physical stores. So is the app just poorly thought out or an attempt at cheap software development without thorough testing, including a beta version? By the way, the App Store says the recent update was for bug fixes, presumably solving them! (There’s another review months ago listing similar credit card problems.). My impression is United should scrap these software developers and start over. This really leaves a bad taste.

3. 1/5Gift Card Purchase Feature Is Completely Broken

   I’ve been using this app for the past week specifically to purchase gift cards — which is the most reliable way to secure your miles on in-store purchases without worrying about whether a retailer link properly tracks. Smart strategy, right? Except the app won’t let me do it. Every single attempt to purchase a gift card results in a denial. No clear error message, no explanation — just a dead end. I’ve done my homework: verified my account settings, confirmed cookies are enabled, and even followed the workarounds circulating on Reddit and travel miles forums (delete and reinstall, turn off Wi-Fi, toggle settings back and forth). None of it works consistently, and none of it should be necessary in the first place. The real-world impact is real: I’ve been left standing at checkout, holding up the line, unable to complete a purchase because the one reliable method the app offers doesn’t function. That’s embarrassing and completely avoidable. This isn’t a fringe bug — search any travel rewards forum and you’ll find pages of users hitting the same wall. United, this needs to be a priority fix, not a workaround users have to crowdsource themselves. The concept is solid. The execution is broken. Please fix the gift card purchase flow so the app actually does what it promises.

4. 1/5MAJOR flaw in redesign re. LOCATION search

   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.

5. 4/5Bad customer service

   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.
