I had 1 hour to connect flights. Boarded the first plane with a broken restroom and captain decided that the 1.25 hour flight couldn’t leave until fixed. Needless to say, I missed my connecting flight and will arrive at my final destination 6 hours late.

I had 1 hour to connect flights. Boarded the first plane with a broken restroom and captain decided that the 1.25 hour flight couldn’t leave until fixed. Needless to say, I missed my connecting flight and will arrive at my final destination 6 hours late.

No service on New Orleans to DFW or DFW to San Antonio. Also no explanation from the captain why we had no AC. Unacceptable!

Flight was delayed three times and we had an international connecting flight which we would’ve missed but AA manage to find us a flight that allowed us to catch and we made our international flight. However, due to the flight change, I’m in Amman, Jordan missing all 4 bags. It’s been a nightmare. Been waiting since June 17 and today is June 20th. Still without luggage. Customer service wait times are two hours and I get disconnected while waiting. I’ll update when/if my luggage arrives. Every day is costing money in a hotel in Amman. I can’t continue my trip to Palestine until the luggage arrives. Then, I will be updating my review.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

Boarding on time and fight was early but they didn't let us off the plane on time so we missed our connecting flight to Japan.

There was a delay that affected all passengers with connecting flights.

Had to wait a long time for wheelchair in Dallas

Horrible. 4 hrs delayed with no explanation for the multiple push outs of time. Wi-Fi didn’t work properly and air vent above seat was partially clogged. Bathroom sink did not work. Anything else you want to know?

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.
