Plenty of overhead space but forced to check my carry-ons both legs

Plenty of overhead space but forced to check my carry-ons both legs

Overall flight was as expected. It would have been better with a couple options for snack instead of only one item and if there was a TV or music as option. But overall satisfied.

The flight from CLE to JFK was fantasti! Pilots and cre were informative and accommodating.

Deparature was late, which is annoying but the arrival was fine and the baggage came early.

No explanation of why there was no snack and drink service (unless requested) when there was service in the other direction.

The First class experience was really good!! Customer service was excellent.

AA is fabulous. However , Iberia cancelled our Boston - Barcelona flight the morning of the flight - 9/16/24. This was almost a week ago and we have still heard nothing from Iberia/Vueling. Found out from a kayak email that morning that the flight was cancelled. Iberia Customer service reps wouldn’t help us and said to call Vueling. No one answers phone at Vueling. Terrible wild goose chase on DAY OF TRAVEL. AA came to our rescue.

Boston ticket agent Cheryl Porter is WONDERFUL. Our Iberia flight to Barcelona was cancelled the morning we were scheduled to leave and Cheryl was our super hero - she found us seats on a flight to London and on to Barcelona. Truly a “can-do” attitude which we appreciated so much after the Iberia ticket agents told us there was “absolutely nothing they could do”. (As did the customer service agents at Iberia’s call center) Ms Porter is truly a wonderful person who genuinely cares about travelers!

The foot ottoman cushion was missing on my business class seat.. the hydraulics is on its last leg & seat cushions do not have support or paddling. Heavily dented by butts

Easy trip, left on time. Very impressed. Great pilot who talked to us
