Terrible steward... Plane was quite empty... I asked to move "back" in the plane and the steward said no... Unnecessary power trip of mediocre people.

Terrible steward... Plane was quite empty... I asked to move "back" in the plane and the steward said no... Unnecessary power trip of mediocre people.

Everything was fine except the end of the flight. We spent more than an hour circling around Miami due to weather conditions. That was not good.

For a 4 1/2 hour international flight all we got was 1 small pack of cookies and a drink. You had to watch movies on your own devise.

The seat was quite comfortable. The recline was enough that I could sleep a little. The crew was professional and good.

On time flight, good communication about boarding, lines didn't form unnecessarily for boarding before their group was announced (kept aisles clear), friendly flight attendants and service

A chaotic and uncomfortable experience from start to finish. The boarding process was a disaster; despite group numbers, it was a free-for-all that the staff failed to manage (especially after group 5). Once on board, the "entertainment" was non-existent. There are no seatback screens, and the mobile app selection is incredibly thin. The hardware is severely dated. My seat had zero cushioning left—it felt like sitting on a hard board for the entire flight—and the legroom was cramped. To make matters worse, the bathroom was repulsive, with toilet paper, soiled paper towels and liquid/pee all over the floor. When I did interact with the crew, they provided the absolute bare minimum and made me feel like an inconvenience for asking for anything. Avoid this flight if you can.

British Airways is an excellent airline. Comfort, food and airline personnel.

Maintenance took a very long time and then we were in a holding pattern. While a one-off maintenance issue is standard, there were delays on both of my flights for this trip based on maintenance issues with the planes, which delayed both flights over 45 minutes. Thankfully, I didn't have any connections but it wasn't an experience that would make me pick AA if I have other options.

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

The captain brought my 6 year old son into the cockpit and allowed him to ask questions, sit in the captain’s chair and talk about all the gears and levers. Made the trip very special for him.
