The business class seats are dated and uncomfortable. The space is bare minimum and there is absolutely no privacy. For $4K, this is not what I expect.

The business class seats are dated and uncomfortable. The space is bare minimum and there is absolutely no privacy. For $4K, this is not what I expect.

Flight, food and crew were all good, friendly and very satisfactory.

Lost luggage after 2 days no word leaving on cruise no stuff or clothes

Staff's did their best to make everyone comfortable and I appreciate them for it

Pathetic check in experience once again. Not enough staff scheduled at bag drop or for special assistance at LHR. Really need to rethink the whole self check in procedure. The crew was good. A very decent selection of special meals in this leg as compared to the JFK-LHR leg.

Very clean and comfortable cabin. Amazing Mediterranean salad for lunch before landing. Great range of films to watch. Really quiet and easy to sleep on the flight also. The initial food was a bit weird: odd fried chicken pieces in some weird white gloop, but that would be my lack of cultural knowledge on the grub. Salad more than made up for it at the other end. Staff were super attentive and helpful. Great and easy flight

I flew Business Class. Rory, one of the Cabin stewards, was attentive, explained the menu, provided appropriate drinks. was

The flight crew were friendly and attentive. Food was good and they passed out ice cream and drinks awhile after Lunch was done. The ice cream was a nice treat! I found several movies to watch during the flight. There was many movies and tv shows to choose from. We flew Premium economy and there was enough leg room to be comfortable. The seats were also comfortable. I would fly AA again if the airfare isn’t expensive.

Gate check bags that had to be gate checked because of first flight being a small flight are missing. British airways lost the luggage and haven’t met up with them yet!

Staff lovely , economy seats very uncomfortable , wheelchair assistance wonderful in Heathrow awful in Nashville !

Qatar Airways only had spicy meals on the menu in economy class. You might want to get food in the airport before boarding.

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Friendly crew. Poor food service maybe due to full flight. All in all, you get what you pay for.

There was a fowl odour coming from the lavatory the entire flight

I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).

They have the most inexperienced / rude flight staff I’ve encountered

I paid extra for a seat closer to the front. The TV didn’t work at all for the entire flight. Would have been nice to know before I purchased an “upgraded “ seat

The plane was late to leave.. Internet was lousy. TV was not working. when we arrived, We stayed on the plane for a long time before we got to the gate. It took us a long time to retrieve our luggage because they didn’t know what carousel to send them to. It was a bad experience.

I especially liked the lead crew officer. His boarding and safety announcements were made with a bit of novelty and humor. The flight also left the gate 10 minutes early and we landed about 20 minutes early… It was a delightful flight…
