Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

Great crew, excellent landing, good food. Over all great experience. Thank you!

Older aircraft, no meal, only food was for purchase. Not impressed United.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Always wish for more healthy, gluten free options. We have to bring our own.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

This flight leg was fantastic - super comfortable and a great selection of things to watch on the TV. Staff were excellent, really above and beyond.

Other than a way way too cold cabinets for the entire flight, all was great

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

The flight attendants were very rude, beyond comprehension. I took a business class from London to SFO for the first time on United. When I asked for a second piece of bread during dinner, the serving attendant threw a 3rd bread on my plate and said, “here. You can have this one too”! I couldn’t believe the rudeness of the attendant. Most all attendants were very rude, unhelpful, sing the food was absolutely disgusting. Never fly United internationally in business class. My flight back to SFO was a nightmare!!

Nice comfortable flight from Barcelona back to the states. The premium economy offers the extra room we need for my husband. The food was good and our flight attendants were excellent.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

Very crowded flight but what can you expect these days?? Crew was accommodating.

Small outdated plane from Philly to Des Moines with very uncomfortable seats. The plane was old, so we had mechanical issues that delayed us for 3 hours with very little communication. It was a very unpleasant experience and I will try to never fly AA again.

The seats in economy were appeared to be quite thin and lack sufficient cushioning to be comfortable. Perhaps it was my seating position but the plane seemed notably load.

Internet was a bit expensive and did not work ask that week otherwise a good flight

They don't make it easy or promote their food options. Dirty plane. Delayed.

International baggage recheck process in Philadelphia was a disaster. Waited 1 hour and 45 minutes to receive our bags. Waited 15 minutes to recheck bags, flight notification boards were blank so we asked an AA representative for our connecting gate and we were directed to the wrong terminal and gate. Our connection window was over 3 hours and we made our flight by 5 minutes. We pulled away from the gate and sat on the runway for 1 1/2 hours. 1 of our 4 bags didn’t make it to Phoenix. The mobile app for lost baggage didn’t work, the AA rep had to manually fix.

I miss my flight and they could not rebook me that day because the other flight was full, and for the next day I had to pay a whole new fee again which I think is unprofessional

The flight had a delay that made me being in a real rush to take the second flight. The delay was almost for 2 hours. They moved us from gate to gate in 4 times. Once I arrived to Philadelphia, I got to run thorough all the airport, as the train was already closed by that time. So I got sick with asthma for all the running I had to do. And I was the last one to board, when it was almost closed. So irresponsable with the people
