I always appreciate when everything is on time! In this flight you have a short connection and it could be stressful , but is was easy and fast. They even ask people to wait so the ones that have a short connection could leave before. It was the fist time that something like this happened.

I always appreciate when everything is on time! In this flight you have a short connection and it could be stressful , but is was easy and fast. They even ask people to wait so the ones that have a short connection could leave before. It was the fist time that something like this happened.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

I had a bad experience with the security at IAH and felt like a sardine on all 4 legs of my journey.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious.

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious. this return flight not as tasty, but filling.

So awful Unreliable Unfriendly Bad Mad Mean Smelly Hot Late Overbooked Understaffed Expensive Cramped Narcs If they were a fruit they’d be rotten durian

It’s a great flight. Service is good. Staff is awesome.

Boarding on time and fight was early but they didn't let us off the plane on time so we missed our connecting flight to Japan.

DFW-LHR Toilets not kept clean Too cramped. Aisles so narrow crew were constantly banging into people on the aisle seats. Even then, the carts used are reduced width. Other than that it was a decent flight on both legs

Eventless. It was a good flight and good crew. Can’t complaint.

Update.us on flight information in a more timely manner. Don’t say we are boarding on time ten minutes before the boarding time when the aircraft isn’t arriving for another forty minutes.

Several delays. Next flight was worse. Did not arrive home until 2am PT

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

You get what you pay for. In general I like the service and flight attendants.

Excellent! Outstanding customer service, the best service I have received. Food was served, dinner, snacks, beverages, crew was there to greet you. 10/10

Charging $300 to be able to pick a seat next to your wife was nothing less than extortion.

My carry-on bag was taken from me when I boarded. It was checked through to London at no charge. It took a big of shuffling, but I was glad not to need to mind it until baggage claim.

Great to have power available for every seat in Premium Economy. I do wish the WiFi was less expensive. It was 23-24 Euros for the flight for one device. And there were times it was unavailable.

I’m very mad because I paid an extra $105 to change seats to an exit row with more leg room. The app clearly showed a gap in between the seats in the row I changed my seat to and I paid for it. When I boarded the plane, it wasn’t an exit row seat and no more room than my original seat. I feel like I was ripped off $105.

The crew on AA international flights in my experience are generally lazy, rude, and inefficient. These guys did not disappoint.

I had a great experience , crew was great and enjoyed the entertainment options I will be booking my next International trip with them .

Front desk was closed at 6 pm, I was unable to get my boarding pass and as such missed my connecting flight home.

I wish they could put the pre-tsa check on the tickets or global entry.
