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

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

Reliable, nice crew, I fly often on that flight and I like it all.

Efficient all round, very good crew. Short flight so the food, of course, was just snacks

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

So far so good but food and entertainment are not available for this flight

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

lots of delays the crew were unclear about where to pick up my carry-on, which they took from me to check in on the plane.

Cramped seats. Audio jack for the in -flight entertainment was broken.

Horrible, delayed 3 hours due to a mechanical issue where the plane is deemed unsafe so we had to deplane after an hour on the tarmac. No credit was given even though plenty of passengers missed their connecting flights and then the baggage claim info showed that no flight was being loaded on the carousel whilst the bags were being dropped, so no one knew if it was the right flight or not since the arrivals screen didn’t show anything.

We traveled with a 7 year old that has autism and he is significantly cognitively delayed. Your site makes it known there are no wagons allowed even if they fold down flat and many autistic children cannot travel without one because they are unable to follow directions or cooperate with walking through the airport and are too big for a stroller. Please consider making exceptions for our special needs children. Also it would be very thoughtful if you’d allow seat selection for no fee for special needs families. The autistic child we traveled with must sit behind another adult in our family because he continuously kicks the seat in front of him and is unable to understand why that is disruptive. We had to pay quite a bit extra to have our 4 seats situated with 2 in row 19 and 2 in row 20 directly behind.

I loved the fact it was on time and it was a smooth flight to my destination.

Service was okay except attendant over served alcohol to passenger and passenger got tipsy and made me uncomfortable

Could not make the flight. No one would help us at all

The agents at the Kelowna YLW airport were really grumpy. Same with oversized baggage person. Staff on the plane were great.

Great flight, great landing, nice staff. Our seats were a little cramped.

Overall good experience. The wait for baggage at our destination was quite long, but other than that everything was good as expected

Do not fly on WestJet if you have a connection. It failed to integrate with my connecting Delta flight and I almost missed it.

There was a man who was very rude at boarding. On the other hand personal bag measuring box is too small compared to USA airlines,

The flight was delay roughly 90 minutes. Once we arrived at O'Hare, we sat on the tarmac for another 90 minutes. I understand that O'Hare is under construction however they need to figure out a solution as every incoming flight I have been on has been delayed coming to a gate.

We were stuck with no gate upon landing for 90 minutes. Unacceptable.

This may have been the hottest cabin temperatures I have experienced on any flight prior to take off lasting for approximately 30 minutes. I am not typically one to complain but I was genuinely worried about the health of several passengers on the flight due to the extreme temperatures including a small toddler.

I got bumped by Qantas to American Airlines incurring a 6 hr layover at lax. I was not happy

The flight was on time and crew were nice, seats were tight and there was entertainment available

Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.

They cancelled my flight and downgraded me to economy and only gave me $250 for the downgrade

The luggage was completely damaged. It was ripped at the corner and the lock was stuck. We had to rip it open.

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints

Incompetent crew at the boarding counter. Never flying AA again.

Snacks and drinks should be served together and air hostess was not supportive with no smile which was kind of disappointing.

After 3 hours of delays, they ended up cancelling my flight. And although I could purchase one-way tickets to get to my destination, they would not offer me these flights as compensation for the cancelled flight, and I didn't end up making it home until 13 hours after I was originally supposed to arrive. It made for an extremely strenuous end to an otherwise good trip.

It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

Bad service as well. Another 3hr delayed flight from chicago to Charlotte.

Terrible. 3 missed flights and 24 hours delayed with lost bag and promised $100 compensation from United and absolutely nothing from them…

Minimal food offered (crackers). Had to clean the seat with a wet wipe because of dried food.

TV Bathroom sink was full of water not draining. Counter all wet

unexplained delays rude staff (why do we have these people on board? No one needs the silly isle clogging drink cart) missed important appointments and spent nearly a day in the airport due to delays that were not made known prior to arriving reserved / paid -for seats not kept, but I was not reimbursed Will be writing to my local representatives, you need heavy federal regulations applied to your industry to protest customers.

I was never allowed to get checked in to United (Air Canada was booked but moved to United). Tried to check in amd was told our tickets was suspended. Called United and was told tickets were paid for but there was an unknown issue with Kayak. Called Kayak and could NEVER get to a live person. I WILL NEVER BOOK ANYTHING WITH KAYAK AGAIN! I had to spend another $2300 and book with Hotwire.

Delayed because of some passengers being held up or late coming to security. Not fair to all of us who arrived over 2 hours early
