I’m going to try and keep this app review unbiased, because of my last 20 (yes, twenty) flights with American Airlines, not a single one has been on time, and multiple have been flat out canceled. But for this new adventure with AA, it was a technological glitch that led to disaster. Yesterday, I checked in for my flight (which I know because I explicitly remember choosing my seat and being bummed about a middle seat). Today, I arrived at the airport two hours early, went through TSA with no problem, no problem showed on my app, so I thought I was all set. But when I went to board, I realized the app didn’t have my boarding pass. I tried to go get it printed at the front, but they very rudely told me to wait in line (which was the standby line, FYI). 30 minutes later, when the line was finally done, they told me I WASN’T checked in and it was too late, there were no seats. Probably because they’d given it to the standby people in front of me. So, 1) the app needs to SAY something when you aren’t checked in. This is a usability thing - not a single warning message to say I’m not checked in. 2) not app related but I’m going to say it anyways, if you read all the way to the end of this review then take it from an AA regular - do NOT EVER take American Airlines again. It’s a realbummer because they have some convenient flights from my location, but I will now be paying whatever extra cost I have to at another airline in order to avoid AA. 20+ chances was too many.
