Flight was delayed for about an hour but overall good experience

We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

Second flight in a row where the entertainment system is broken. 5 hour long flight with no entertainment and flight attendants did not seem interested in resolving the matter. Very shocked to be treated this poorly considering I paid for a first class experience and have Diamond Medallion status.

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

The flights were on time- Great service Would have liked more options for food choices.

The brakes on the A220 are sensitive and uncomfortably grabby

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

Flight cancelled because of the grounded 737s. United was good about it and got us onto a later Alaska Airlines flight to Oakland (not San Francisco as originally intended). Had to go through security again and my wife dropped her MacBook Pro, which broke, a $2,500 whoopsie. But we made it home.

I liked being upgraded to first class. The flight was a redeye, so I did sleep most of it.

Luggage took too long go get off plane in Knoxville. Was almost 45 minutes after the flight landed.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

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

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

As smooth as you can expect. Some issues with boarding because the previous plane took forever to deplane but overall, a good experience.

DFW-LHR Toilets not kept clean Too cramped. Aisles so narrow crew were constantly banging into people on the aisle seats. Even then, the carts used are reduced width. Other than that it was a decent flight on both legs

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

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

The flight itself was fine, but between the man in front of me putting his chair back, and the gentleman next to me who took up 50% of my seat, my back and neck are destroyed from the flight. I’m hoping for a better outcome flying back.

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.
