They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Ac was broken so we deplaned, waited 2 hours, taxiing for takeoff they said the plane would not fly so we went back to the gate and got a new plane which took another hour. In all a 4 hour delay for an 80 min flight.

Horrible people at the gate, they force me to check in my carry on, even thought no one behind me has to do it. I had to get out of the airport in NY to get my bag and go thru security again on my way to Honk Kong. The worst part is the employee threatened me with loosing the flights if don’t comply.

Delayed flight, few announcements with information, no comps, cluster f boarding because zones weren’t spread out and announced loud and repeatedly, staff did their job -nothing more nothing less, annoying kids were speaking and kicking the heck out of the back of my seat and parents weren’t willing to parent… so another typical day of air travel in the US.,

Flight was delayed until Next day as crew timed out

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

I was able to get on standby with relative ease

Terrible, oxygen masks were deployed mid-flight. We returned to airport. Took additional 12 hours to get home.

6 plus hour delay with no explanation. No wheelchairs to transport us on arrival. Very disappointed.
