We waitied for 2 hours for flights to take off. Make us to seat 2 hours in small space is not good.

Wheel Chair Access sucked. I had a guy from Bangaldesh drop me off without taking me to the gate

comfy and spacious seats for premium economy, nice flight attendants. only problem was the wifi did not work, and my entertainment screen was locked in Arabic language and all kids shows with no way of seemingly changing it. but the flight was fine and I arrived with no issues

It was hot. Need more A/C blowing with more pressure from the overhead vents.

We left nearly 40 minutes late, which is a long time when you're just seated and waiting. Otherwise, it went well.

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

Terrible. I did not like the delay without recourses to help passengers to get to their destinations. AA used to offer coupons for food and overnight accommodation, but not this time. The flight planning was terrible despite of all the current technology available; AA could have informed passengers better that the replacement flight is impossible today, instead of stringing passengers along for 6 hours before cancellation, so that passengers can make earlier alternative arrangements to get home.

It was a bus not a flight. Okay bus ride.

My trip was delayed for more than 3 hours without any explanation. Also I have a business meeting that I lost.

If we travel with carry on expected to being able to carry the luggage. Could be good if take in consideration the date of reservation to do that
