United has been holding my money for a cancel on another ticket they wouldn’t let me fly for going on 5 months. Terrible service I wouldn’t choose to buy tickets or fly with united again. Very bad experience generally dishonorable and poor service .

The seats were very nice in premium economy. The service was good. The flight was slightly bumpy. Would have appreciated more updates from the pilots.

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Airline tickets are not cheap. You expect reliable competent service. Thanks to canceled flights and botched transfers we arrived at our destination two days late. This is not acceptable

The flight got delayed. They forgot to bring the drinks when I asked for it. The toilet is messy.

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

Flight was delayed three times and we had an international connecting flight which we would’ve missed but AA manage to find us a flight that allowed us to catch and we made our international flight. However, due to the flight change, I’m in Amman, Jordan missing all 4 bags. It’s been a nightmare. Been waiting since June 17 and today is June 20th. Still without luggage. Customer service wait times are two hours and I get disconnected while waiting. I’ll update when/if my luggage arrives. Every day is costing money in a hotel in Amman. I can’t continue my trip to Palestine until the luggage arrives. Then, I will be updating my review.

They did not offer coffee on a 7am flight…awful!!

Plane temperature was so hot that everyone on the plane was sweating. Departure gates changed 3 times in the hour before the flight. Internet service was so poor in the terminal that updates weren't always being received.

We had a mechanical delay which made us 90 minutes late (9:30 PM) then land and put into the penalty box because a plane was in our gate? What the hell! We should get priority.Damn American.

Check in for 5am flight at RDU was hampered by American check in counters being seriously understaffed , was told even supervisor called out. Took so long in line for special services check in that we missed our 5am departure even after arriving at 3:30am. Had to be rescheduled to later flight from Charlotte to St Thomas.

Delayed flight due to maintenance and I have had multiple delayed flights due to maintenance in the last month plus

Excellent service. Flight attendance like Jessica,, on our flight, is a reason I wouldn’t mind flying through British Airways again. Jessica,, was very courteous and helpful.

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

Significant delays on my trip to Chicago and my trip back to NY

Terrible boarding and first class experience. Nice staff but overall disorganized, dirty plane.
