Our flight was delayed to Louisville. What made this worse was they did not have another flight attendant to service the flight. This caused an even longer delay. Then when a flight attendant did show up, she chose to "swap" flights with another flight attendant. Therefore, we had to wait longer for the other flight attendant to come to our flight. This is information that the gate attendant should not have shared. Processes and execution at American are broken. Passengers are feeling it. Fixing this starts at the top of the organization.

The gate got changed several times and the flight was delayed over an hour. Awful experience

It was an older plane. First Class was not especially roomy or comfortable. It was a short flight so there were no meal but they did offer mixed nuts which used to be normal but now is rare. Crew member was very polite and professional.

No Snacks or Entertainment. The flight was short, snacks should still be given.

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

My Internet did not work for Outlook email or basically anything. I paid for one hour of in-flight usage and it was terrible. I spent a lot of time on different sites and browsers with no luck and a lot of frustration. Other than that, the flight was on time, crew was nice, service was fine. Seat was OK even though I paid for the extra 6 inches. I cannot imagine how tight the seats in the back must be.

Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.

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!

I was not given the option to get on a different flight even though I was going to miss my connection due to weather delays (I did). When I called early in the morning, they said it wasn't delayed long enough; though I knew it would be by the time it was time for the flight ... it was and by that time it was too late. I wasn't given the option to pre-board with my toddler, and the food service was less than normal due to delays .... at least that's what the crew said.

Nothing wrong on this flight but nothing special. It was oversold and they had to bump people which is always bad.
