It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

AA had a nationwide tech glitch today and after two connections snd hours of delay, I arrived 7 hours late to my destination

The plane was very warm and the crew turned on the lights for the entire snack service.

There were several issues with this flight. I have flown quite often internationally and I was surprised by the lack of presence of attendants other than meal and drink times. The food was not best but I feel that is the norm. We also had to get off the plane once in London via stairs and bus to the terminal. Anyone who had another flight had to then get another bus to another terminal. This causes me to miss my flight and have to rebook.

Due to an issue with the plane. We waited almost 2 hours to take off. The service reps were great. We had a longer layover but was able to run for it and catch our flight. This also happened on our way out. Maybe the planes need a good look over. The people who work front desk and flight attendants are the best

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

The boarding process was incredibly slow, as was deplaning. They started beverage service and there was an extremely small amount of turbulence, so they discontinued it. They said they’d resume if possible, but even thought the rest of the flight was perfectly smooth, they didn’t bother. Getting our checked bags took longer than I’ve ever waited and they couldn’t even tell us which carousel they were coming out on, so everyone was running back and forth for 30 minutes.

It was really good. The boarding was good and smooth. They even checked our carry ons if you wanted to without any charge.

Flight was delayed , waited in the tarmac for 3 hours and then came back and was cancelled
