Food was terrible. Going to Italy I gave benefit of the doubt however returning to the USA was no better. Rolls were frozen. Butter was frozen. Quality of entree poor

Cabin crew friendlier, they weren't weren't unfriendly, but simply professional and not more

The crew on AA international flights in my experience are generally lazy, rude, and inefficient. These guys did not disappoint.

The plane sat on the tarmac for 2 hours, it was terrible. No drink service during the flight. Terrible

Comfortable seat Attentive cabin crew Asian vegetarian meal very good Not enough drinks were offered during flight No ice cream Snack offered before landing not good very unpleasant taste no choices

Plane arrived late to gate, staff at Philadelphia had no sense of urgency to get people on the plane. Boarding took 15 min longer than it should have because despite 4 staff working at the gate, only one was scanning tickets while the others sat talking to each other.

When I bought the ticket, right away I got a problem, I had to cancel. Unfortunately never ever I will use kayak or Iberia again. When trying to cancel kayak told me to talk directly with the airline, the airline talked to me through whatsap and told me to deal through kayak. Both of u never took responsibility in helping me out. You kayak did not want to deal with me. I called my credit card and now we r disputing the charge bc u have a pathetic customer service.

Ability to select seating would be nice. We were family of three and they had us seated back to back and one of us on the other side of the plane??? That is pretty goofy. Especially when tickets were placed two months in advance.

How to get an aisle seat without paying extra? The young lady next to me was assigned the seat.

Flight reservation was canceled withou notice had to spend the night in the airport

Thanks to a delay of an hour of my flight to Philadelphia on American Airlines I missed my connecting flight to Amsterdam. On arrival at Philadelphia he crew on the delayed flight did not ask the passengers to let connecting passengers get off first and I arrived a few minutes after boarding was closed at the original time for the flight to AMS, this despite the fact that I had received a message from American Airlines that departure was delayed by 25 minutes. Overall very poor service, no effort from the part of American Airlines to accommodate the passenger, just rebook the flight for the next day.

I liked my seats on the return trip. Didn't like having to pay for luggage on an international flight. Also didn't like that it was on American airlines and not British Airways. I specifically selected a BA flight to experience that airline.

Somone switched seats to sit near friend causing us to be disconnected (3) business class. Very disappointed. Staff did nothing.

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.

Besides having a LONG layover in Philadelphia to begin with, our flight was delayed and left late. We spent 7 hours in the Philadelphia airport after being in the air 7 hours from Portugal to Philly. It turned into a 24 hour day of travel which was exhausting. I know you can't help weather but our layover was difficult as my husband is handicapped. The staff was EXTREMELY helpful with his wheelchair tho!!

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

The company that I bought my tickets through, Cheapflightsfares, failed to provide my confirmation information in a timely manner, so I was unable to check on at the country and therefore unable to make my flight. As a matter of fact, I STILL have not received the confirmation. After having read more and more reviews about the company, Cheapflightsfares appears to have scammed hundreds of hopeful travelers out of thousands of dollars. Please look into this company and, for the sake of anyone planning their next trip, stop allowing them to do business through you.

The plane was known to be late in advance of takeoff. My guess is that it was known to be late at 11am or 5 hours before scheduled takeoff time. We were late to leave and with a wheelchair and the a cart, we only made it to gate. We raced! Inside plane, all was great

The decided to just remove our booking without telling us. It ended up costing us thousands

Is it American Airlines or British Airways? This is so confusing. I got it from Portugal.
