Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

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

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

We had selected seats in the app that were a 2x2 format in the middle of the plane. Our seats when we got on the plane had been moved to the back rows in a 3x1 format. What’s the point of paying up for tickets that allow seat selection if the airline will just change them?

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

Flight attendants and crew were great! This plane was fine. It was clean and everything worked properly. Now, the gate change was not communicated. No text or information. It wasn't far with the gate change but it still changed without any communication. Not sure if this is on American or Kayakl. Also, internet was the worst. I would never have ATT. 3+hr flight and weak internet. I think I watched the commercials to get on at least 6 times. Terrible internet!

So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

Dreadful experience. Our flight was delayed more than 8 hours due to a maintenance issue and the assistance from rebooking was poor. I was travelling with a bad knee and needed assistance waited in one place more than 3 hours before someone came with a wheelchair. The woman next to me was a 91 year old great grandmother who had waited more than 4 hours. There were moments of support from the staff but it appeared as they were going against the direction of management. It was apathy, lack of ownership and dismissive responses with small moments of kindness and understanding typically from grey haired, female, veteran staff..

Experience was fine. Seats were cramped, and we had to wait for repairs before we could take of. Even though the door remained open, we were warned that leaving the plane could cause difficulty trying to fly out later. Staff was pleasant, and climate control was fortunately working. We had trouble at the DFW terminal, but I don't think that was AA's fault.

Boarding, Seating, Flight Attendants, flight was okay. My seat was uncomfortable.

I had the exit seat with all the leg room I could ask for. Great!

I wish there were no credit card announcements. I paid hundreds of dollars, I don't need to pay again by sitting through advertisements.

The flight got delayed more than an hour due to maintenance issue after the passengers were all on board. I missed my connecting flight and had a trouble finding a next flight. The crews didn’t seem to care about the inconvenience of the passengers missing a next flight. It was very frustrating experience flying with American Airlines. I will not fly with AA in the future.

This flight was cancelled and I was passed around and given four different flight plans that got me in PV a full day late. I had to rebook a different flight with Delta and that was amazing
