The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Even though we were delayed, we were able to make our connection

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

The internet service I paid for didn’t work at all and the flight crew was not very friendly.

The best airline I have ever travel , really good customer service, attention and service !!

One the best cabin crew team we have ever had (I have flown globally for more than 2 million miles), food was good and wines choices were great.⁰

Not much space for someone 6 feet high in normal economy seat. My knee hurt

Not to have gotten delayed by 2+ hours for the fourth straight American flight. They're the worst.

Did not get any refreshments. Crew was very nice but limited. Small seats

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

I couldn't use their app to select seats or check in because they made a business partnership with UnderPricer to control and sell those options when you purchase your tickets through that agency. And yiu can't get any assistance from UnderPricer. Vueling has made a terrible business decision to partner with them.

I didn’t like anything, being platinum pro get you absolutely nowhere and does not increase the customer service treatment whatsoever anymore. My flight was canceled and they put me on a flight eight hours later that would’ve got me back in the middle of the night. They could’ve easily move me up to an hour Prior on an earlier flight. My second flight was unreasonable to take, the third flight was also canceled due to mechanical issues like the first flight. I don’t know what’s going on with American, but they are falling apart, after seven flight changes I finally got home, Unreasonable.

This was a horrible American Airlines experience, and it discourages me from flying with them again. It may have stemmed from a mechanical delay, but it appeared that the team was unprepared to respond to the delay. After boarding, we waited an hour before finally taking off. After landing at our destination, we waited an additional hour on the tarmac waiting for a gate (at 8:00pm) to be assigned and cleared. The flight crew did their best, but they were clearly tired and also ready to be done for the day. Because of the delay, I missed a connecting flight. It was a very poor experience.

Fantastic! If it had not been for a check-in agent in Knoxville I may have not gotten my passes on British Airways. I couldn’t check-in online because British Airways had messed us the info on my tickets to London & Inverness. AA’s was great! British Airways was a continuous series of delays and frustrations.

Seriously, not displaying departure gate until very last minute is awful. Specially when you have to take an elevator and then transport to go to the sub-terminal. That’s awful in such a busy airport as Heathrow. And I cannot choose seat on this flight because it’s run by British Airways, even entering locator code.

Wheelchair was waiting for me,changed to a better seat which was great as it's hard for me to walk

We were never able to take this flight because our first flight from Austin to Dallas was cancelled.

As I said Al & AJ were absolutely the best and wow they should be recognized for their amazing service!

Flight was on time. Boarding process was tedious. Not much overhead cabin space. Seats very close (front to back). Uneventful trip just the same.

The crew will not help you with the overhead bin even if you are business class. If they do, there's always the sentence " we are not supposed to lift anything".... To charge for seat assignment in business class is nothing short of money grabbing/ ripoff. The ground service in London is better than Vancouver, which was atrocious.

Quick boarding process, slight delays on the tarmac prior to takeoff and a late arrival due to an emergency on the landing runway. Not the fault of the airline at all! Cabin crew was very friendly and the Captain kept the passengers well informed about what was going on

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

Excessive delay without proper communication. Mediocre for a BA flight.

Another old plane. This time they changed gates at the last minute and when people arrived boarding was delayed

Still unhappy cancel fight rebooking half of what I paid fore! Terrible!!!!

The food was awful and little, on the plane there was not space to even move in the aisles, the seats were super close to each other, no confortable at all!
