The seats. The seat in front of me was awful and when the guy sat down, it flew back and hit my head when I was putting my backpack under the seat, It didn't make for a pleasant experience,

The middles seats on the 777 airplane are very small. I am only five feet tall and my knees were touching the seat in front of me and the is no leg room if you have a person item under the seat. The food was horrible, spicy sauces, tasteless bread, and wilted/brown lettuce. Keep it simple. The staff was mediocre., one minute loud and chastising, and the other friendly. We liked how clear and easy to understand the entry process in to the US was.

The overhead bins are too small, They served one meal and two snack for a 10hr flight. My meal was missing the butter, cheese and salad dressing everyone else got. The crew were nice and the plane was clean

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

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.

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

The captain announced to the cabin there would be a delay because they observed a "cut" on a tire during precheck that needed to be cleared by maintenance. We were delayed during this inspection and allowed to proceed after maintenance "measured the cut and decided it was acceptable". My complaint is not about the delay or due diligence. I wish the captain had been more generic when making his announcement. I was a nervous wreck all the way to Charlotte worried that we would have a blowout when landing!

Movie selections were very limited. Meals were not f So good.

Delayed, no updates, had a rewards number but was not working

I love American. I’ll never fly anyone else if I can help it.

Overall it was okay. Just the lost baggage and how they are handling it

Puddle-hopper. Quick-ish flight. Don’t expect to have much/any in-flight entertainment (movies/TV, etc).

Worst flight I ever experienced, what was supposed to a 7 hour flight ended being 13 hours on a plane with no ac and the worst cabin I have ever seen. Never again.

Horrible seat at the back. Crew was very kind. Packed plane. Wordy pilot bragging about Iberia being punctual when many of us came from Alicante flight that was delayed an hour and many lost connection and we lost our luggage. Still waiting for it

Excellent plane, 787. Very good seat and additional stuff they provide. Good food. Very good staff.

Excellent except WiFi is a Must on Biz class 10 hour flight ! Didn’t work entire flight. SW doesn’t do that.

Excellent crew, food and service. Boarding via bus is always a pain but overall really good

Stewardess was not attentive at all asked for a bottle of water never came by 15 minutes later I asked her she said that she forgot there was only 12 people in first class and two stewardess unacceptable I ordered the fish was the last person to order. They said that they did not have any had to have a different item pasta at the inside of it because I was diabetic. Worst experience I ever had will never travel this airline again.

It’s got the tightest seats of any airline - my knees were smashed for 3 hours - absolutely awful.

Flight was fine - however my husband's checked in case was damaged, and mine still has not arrived

Service and food was amazing. Aircraft configuration is weird - stare at a stranger at take off and landing, during flight someone is crawling over your seat. It was lame.

The flight from Dallas to madrid was delayed for 2 to 3 hours, the flight back from Dallas to Sacramento was fine , but there were 5 gate changes within the span of 2 hours, last one was in a differny terminal. Flight and crew was okay

The flight attendant does not pay attention to my "call" button more than 3 times when I need a drink.

I loved the food choices and the attentiveness of the crew but boarding was chaotic.

Old plane, sold out on snacks, just trashy seats..broken..etc

I liked the movie selection and the speed getting the luggage. I did not like the fact that for premium they did not have a personal kit with toothpaste, I travel all the time in premium economy and bussiness and althought the kit might bot be the same at least you have the smalles kit in premium economy. I did not like either that because i was in the last row of premium economy nothing made it to my seat. They run out of the food I wanted ( it is a surprise because there were only 6-7 rows. They would run out of orange jouice were thy were passing water/orange juice around, they run out of some alcohol. I am undertand running out of it but I don’t understand why mot getting kore. The service I received in row 11 was different from the service in rows 7,8…. Also the screen on my tv was broken. It did not respond to touch. So, in conclusion, if I compare my flight going to Europe with an American airline plane in premium and the one with British, British expereince was significantly much worse. This company is declining fast.

Easy, straightforward boarding process. Flight attendant was lovely and attentive, food was delicious - especially dinner, I had the roasted chicken in a mushroom sauce with potatoes - and entertainment selection was top notch. I would fly with BA again.

I don’t think you’ll like the shoulder require people to pay to reserve seats. Also for the people in the bulkhead row the luggage locker nearest to their seats should be vacant. Both sides were filled with crew or airport items.

Awful. Flight was late. Follow flights cancelled. No person at the British airways counter for hotel voucher. Awful service.

It was good. Couldn’t Check in online and select seats
