I found the seats ergonomically uncomfortable forcing the body to seat slightly hunched. For a short flight I worked on adjustments but for a longer flight, it would be difficult.

I found the seats ergonomically uncomfortable forcing the body to seat slightly hunched. For a short flight I worked on adjustments but for a longer flight, it would be difficult.

I cancelled this flight 2 days before departure but I followed your texts and emails and IF you were correct this flight turned into a nightmare.

Rudest flight attendants ever, waited over 20 for light to be answered and it never was then tried to flag down an attendant who said someone else would come, just needed water to take some medicine Food bad

I was a Wheelchair Assist’ passenger on a London Heathrow to PHL flight yesterday. The process of getting me and my carry-on bag from the ticket counter to the gate was not good at all. It was the worst in my 5 years of experience using this service offered by American. The Philadelphia ‘Wheelchair Assist’ service was, and always has been Excellent! Not so at Heathrow. I was handed off to three different wheelchair drivers; had to sit in a very dingy holding area for 30 minutes while waiting for our gate change announcement; got crammed into a overloaded service vehicle to take me from the holding area to the gate ; was dumped at the end of the line of already-boarding passengers with my heavy carryon and no one helped me up the ramp way at the gate to board the plane. Overall it was a miserable experience!

My flight times changed 4 times since I originally booked the flight. The last time being the day of flight - a 2 hour delay. This meant instead of getting into IAH at 9:30p, I got in at 2:30a. This was very disappointing!!!

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
