Check in was chaotic with only one counter for business class and first class. The luggage conveyor belt at JFK airport was broken so the flight departure was delayed which made the flight stressful as I had a tight connection. Although the captain said they could make up the delay, they didn’t do so.

The luggage conveyor belt at JFK airport was broken so the flight departure was delayed which made the flight stressful as I had a tight connection.

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

The plane was delayed coming in and on the tarmac. I was coming from another flight so it made for a very long day. The stewardess kept trying to slam the overhead bins closed and I was worried that she had damaged my new luggage. They ran out of snacks and lccdsddd me a hummus box which was nice. It took them a very long time to pick up the garbage so I could not go to the washroom and had little time. To prepare for disbarment. The TV system was hard to control from the armrest and picture wasn’t clear. The crew did apologize several times for the lateness. It took the Denver airport an unusually long time to de-ice the plane.

Their app did not recognize my Aeroplan frequent flyer number and would not allow me access to my boarding card. Ground staff was readily available at the airport to print it out to me.

We were already two hours delayed before take off and then had to be diverted. Terrible experience.

The flight de-boarded after being informed of a 3 hour delay. The gate agent said we could go to lounge. The flight ended up boarding 20 minutes later and I missed it.

My experience with American Airlines was great. Unfortunately my stroller was not located and has not been given to me and or reached out in return for in regard to information.

Pilots were fantastic - super smooth. First Class flight attendant was very attentive. Main Cabin flight attendant should try to smooth the rough edges of her voice - very shrill / punitive. Hurt my ears just to listen to her. Recognize they have a (tough) job to do - but tone over speakers needs to be less like scolding a 5 year old.

Maybe focus more on delivering a good product vs selling me a damn credit card

Leave on time. We waited on the plane for hour hours and it was hot and smelly

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

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.

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.
