Was as expected. Good leg room on planes - much appreciated.

Was as expected. Good leg room on planes - much appreciated.

Smaller, regional aircraft limits amount of overhead luggage space. At least there were jetways at both BNA and PHL. First class food service was minimal with the usual assortment of packaged snacks (nothing creative) and no handiwipes. American tries to turn around aircraft too quickly without enough time to clean the planes. WIFI service did not include TV programming.

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

Food choice is limited, entertainment better than average, seat leg room terrible

While I received notice that AA 478 was delayed, the flight departed PHX and arrived PHL more than two hours late. The first class cabin service was mediocre; there were no pre-departure beverages offered; there were no warm mixed nuts served with cocktails; there was no personal greeting to me as an Executive Platinum member by the first class flight attendant. While the flight operated safely, its arrival at 0219 in the morning in PHL ended a very long day. I do not feel that American provided first class service.

My baggage went to Dallas and not to Philadelphia. Do I need to add anything else?

Late arrival due to gate being blocked by stalled truck

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.

We truly had not one problem. Nive enough to receive an upgrade. Flight attendants were extremely friendly and cheeful. Gladly will continue to fly American.

Flight operated on tie. However, the in-flight entertainment was inoperative. No special recognition as an Executive Platinum member.

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

My wife and I paid for seat selection to be together. My wife and I were on separate rows and the excuse they gave was they changed the plane. Also, I have celiac and asked for a gluten free meal in the ticket profile which they did not have.

Seats, comfort level ugh. Crew was not attentive, only to coach

Pros: they tried to accommodate bc they forgot my gluten free meal Negatives: The flight was freeeeeezing Iberia didn’t communicate my gluten free meal

This flight was a code share for both Iberia and American Airlines and run by what I assume is a charter company Level. It was difficult if not impossible to get a seat assigned, check bags or use any customer service functions. I would skip it!

I called prior to flying to confirm our baggage allowance which was 5 bags. On our outbound flight thee were no problems. On the return flight we were charged for each bag totaling $400! We are working with customer service to resolve the issue.

Everything was fantastic except the Iberia website and app… they left a lot of questions and induced much stress. But once on the plane, all was awesome.

I needed assistance and the staff at the airport and crew were very helpful and polite

Premium economy class is pathetic. Rubbed shoulders with passenger next to me all flight. Only about 20 passengers in that class but they ran out of one food option shortly after started serving the main meal. Flight attendant was curt and acted annoyed when asked any questions.

I liked that the seat belt fit so I did not have to ask for an extension.
