Airline reviews

We boarded the plane and were about to take off when we were notified that the tires had to be checked. Upon inspection, they were found to need replacement, so the entire plane had to be deboarded. After we exited the plane, United staff forced us to stay in the gate area by posting "Do Not Exit" signs on the doors connecting the gate area to the terminal. Many of us had already rebooked our flights and had no checked bags, but they told us we could not leave. This seemed inappropriate to hold people under false pretenses. When the agent told us we could leave, I asked them to please take down the "Do Not Exit" signs, as they were misleading. The agent refused, and I told them that it didn't feel right to hold people like that.

Flight attendants had a little attitude. Food tastes no good.

Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

headphone jack didnt work for the first flight and not much variety

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

The seat is too hard and my back and bottom are having servers pain

I suppose to board the plane AC5110 to San Francisco on July 16 2026 @07:00 am and arrive San Francisco at 09:25 am. At 9:30am still in YVR I was told the plane was delayed until 11:30 am to take off. Not until 11:35am the pilot of the plane declared that due to hydraulic system problem this plane was cancelled. After waited in a long pile up for negotiating with the counter-staff, I finally got the tickets for myself and my wife Yim Mei KONG firstly to Seattle and then transferred to San Francisco on the plane AS 2014 & AS 791 with Alaska Airlines. I suppose to attend the funeral of our friend in San Francisco on July 18 and a Memorial Gathering for the Birthday of the deceased on July 16, 2026. I arrived San Francisco at 9:40 pm that day (12 hours later) and couldn't joint the Memorial Gathering. This upset me a lot. I am seeking for compensation of this failing trip. Please let me know how to and where to forward my complaint.

Horrible! Rude flight attendant, barely any service on such a long flight. I wouldn't recommend Air Canada to anyone.

not able to change flight, no customer service from KAYAK

Aircraft is designed with all 3 washrooms at the back of the plane, meaning that when there is service underway, there are no washrooms available and it gets very crowded at the back of the plane.

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.

Moderate size plane, not completely full, easy boarding, some rows with just 2 seats so a couple can have a row to themselves

There was no free food on 5-h flight no snack. Small personal spaces but better than on United flights. I was happy with assigned seat according to my preferences. Boarding and trip was timely and well-organized.

Boarding for all airlines is goofy. Why don't they just board from the rear to the front? Food... what food? The 737-8 is poorly designed. Using the toilets totally interferes with the service crew. Pilots could have been more reassuring about the turbulence we encountered. Cabin crew were exceptional. Flight was on time with little wasted time on ground.

No free snacks, not even pretzels. And the paid snacks are very pricey: $4 for a KitKat bar.
