Seats are made for children. An 8 hour flight with tiny seats is more like a cattle car. Lost bags at Rome airport caused a 7 hour delay.

Seats are made for children. An 8 hour flight with tiny seats is more like a cattle car. Lost bags at Rome airport caused a 7 hour delay.

Set on the plane for two hours before pushing off the gate due to the power source issue being fixed which was known before letting people board the plane. On top of that it was very hot as AC was not working properly. Terrible experience and limited communication provided by the crew on the status of the issue. They should let people deplane while issue is addressed instead of frying them and glued to the seats.

There was not even a single time where united airlines from lga has made to the gate straight , 1 hr if delay today

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

3 hour delay…. Nearly 2 hours sitting on tarmac. Do better, United. Or at least have the sense to not say “we hope you enjoyed your flight with us” upon disembarking.

Everything except the food and entertainment. It was a great experience though

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

Seats are getting smaller and smaller. In flight movies are poor compared to other airlines. Food is mediocre.

AC wasn't working properly and the WiFi was also not working properly for stretches.

It took 1.5 hours for maintenance to sign off on a repair that was completed the night before. When we landed in DC we had to wait 20 mins for a gate. As a result I missed my connection. American seems to be reducing the number of ground ground crew and causing delays. This us not the first time.

The delays were not communicated well at all. I was in the airport for over 9 hours with little knowledge of if I was actually going to reach my destination.

It was OK, but it was delayed about an hour, and my luggage didn't arrive till about an hour and a half after the flight

On time departure & early arrival. Made a long day much better.

The flight attendants were very friendly, efficient, and helpful. The plane was ahead of schedule, and it all went very smoothly. Thank you.

I have a gluten allergy so did have any food

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.
