Airline reviews

I thought American Airlines did well considering the adverse weather situation over July 21 and 22. I especially appreciated the consideration given to me when I got stuck in Miami on my way to Boston from Charleston, West Virginia. Thank you for providing a voucher for an overnight stay. Though it was only a few hours of sleep, it was very helpful. I was able to reschedule my medical appointment and got back to the Boston area on the 1st flight out of Miami as a standby passenger. It was very helpful that I was given number one priority on the standby list.

I had my flight of Cedar Rapids. THen Chicago to Boston. Flight out of Cedar rapids was delayed by 12 hrs. Had to drive to Chicago to catch my flight

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

I was in last row so that is never great bc the person in front of me leaned his seat all the way back into me.

Half of the TSA checkpoints at PHL are closed. Also, there is no standby for first class passengers. You can only standby for coach. Very dated policy and inconsistent with peers.

We had a male flight attendant who was super attentive and wonderful! Very professional. I have both gluten and dairy intolerance, and was only able to get a gluten free part, and not the dairy free part of the meal. Easy to order ahead of time and I appreciate being able to do that.

No enough space plus only allowing one laggage instead of two like other airlines.

AA should improve their in air internet & entertainment options. Seems unreasonable to charge $20/hr and should have some form of free connections. The entertainment options are also pretty limited, movies are outdated and the series only show 3-5 episodes.

I was in a wheelchair and went from international to domestic. I was transferred to several different modes of transport and expected to give a tip at each transfer. I was, although, grateful to get to the gate in time for my flight.

There was no entertainment (the wifi was not working) and no food service - just cookies or pretzels. When we arrived in Boston the bridge to our plane was not working and it took some time to be able to deplane. When we got to Boston our bags were not there and the person who put in our claim for lost baggage said we would have our bags delivered in 24 hours and 72 hours later we still do not have them and no one from AA has contacted us with an update!
