Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight was delayed and missed my connection Lufthansa didn’t respond.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

A little bit more leg room in premium economy. I am 6’4”.

Overall it was good. I missed my connection but I was put on another flight.

Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Gate agent did not hold flight for connection, provided no assistance to get new flight

Boarding experience was smooth. Flight attendants were friendly and helpful. Entertainment system on the Houston-Edmonton flight did not function for passengers on the left side of the aisle. On the bird's eye flight from Quito to Houston, they should not serve a meal. No one needs to eat after midnight and it is disturbing for those passengers trying to sleep.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

Our bags took a long time to get unloaded once we landed.

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

My Internet did not work for Outlook email or basically anything. I paid for one hour of in-flight usage and it was terrible. I spent a lot of time on different sites and browsers with no luck and a lot of frustration. Other than that, the flight was on time, crew was nice, service was fine. Seat was OK even though I paid for the extra 6 inches. I cannot imagine how tight the seats in the back must be.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

No issues. They did change our gate FOUR times in about 30 minutes which was mildly annoying but the flight was fine.

Great flight. No issues at all. I still think boarding could be more efficient but otherwise, a good experience.

Crew should be nicer and emphatic with customers. Same cookies as the past 20 years. Seat are ok and the plane was clean though it was delayed.

Very poor delay in dfw was really bad n long

Because of rescheduling, they had to put me on a flight that didn't go through Dallas

The flight got delayed 2.5 hrs due to a maintenance issue that cause a domino effect. American should have spare planes for when something like this happens.
