Airline reviews

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Staff was rude. Didn’t give water for 2 hours. Worst service

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

We were given vouchers we couldn’t use with a 5.5 hour delay

Delay and keep changing gates. I have to run around from B to C then to E.

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

It was a smooth flight both in the sky and landing!

Fare was great, seat comfort the opposite as cushion was worn out. Ok for 2 hour flight, not for 4.5 hour flight..

For the price, it was a really good experience. There was no entertainment on board, so I couldn't really rate this, and I didn't order a meal. I appreciated that there was a free glass of wine.

Very bad, flight was cancelled due to strike and staff was unable to rebook us

Air Canada is my new fave airline..I plan to use when I can. No complaints at all just rave compliments for the staff and airline.

Strike pissed me n stranded in middle of no where

No paper towels in bathroom. Aisle seat difficult to get out of Other than those, excellent service

Plane was packed but flew on-time, and the comfort level was great! All planes are a bit cramped, but the in flight entertainment was superb, snacks were nice, and the crew was polite. Got into Calgary on schedule...all we could ask for

All good but I could barely get my arms and legs into the room in front of me. Have never been so cramped before. Plane left the gate on time, taxied very quickly and took off without waiting. Unique. Arrival on time. No problem
