I was put on an Air Canada flight and sat on the tarmac for almost THREE hours in MTL. Finally took off and am stuck in Toronto overnight. Air Canada was very unhelpful. I have to sleep in the airport. No food vouchers. Sucks.

The seats in this small plane were comfortable with decent spacing, decent legroom.

One flight attendant, too much work for one.. $8 dollars to use tv, $6 for wifi.

Crew was friendly and the flights were successful and safe.

Boarding with Groups makes passengers line up into the walkways and block other people from getting past easily. The middle seats used to have the most under seat storage space (the best benefit for that middle seat) and now it is as small as the aisle and window seat's space. Offering no free snacks (crackers, nuts or cookies) with free drinks is wrong. All other airlines I've been on do so happily. We had 55 minutes between flights, but the first flight was late arriving at gate F and the next one was at the other end of gate C. We just made it with no time to use the bathroom along the way...

The crew could not have been better. I was really pleased with the movie selection. However, the food is really terrible. I got a dish that was chicken, mashed potatoes and green beans, which would have been acceptable had it not been covered in bbq sauce.

The fact that my original seats were not given. The other issue was that Alaska wasn’t my airline but American was. They didn’t even tell me until I got to the gate, moved over to another and then got transferred over to my gate.

Boarding was good, but pretty bad flights overall. One of the worst I ever had in my life! The plane seats we had had so little cushion that is was painful to sit. My husband was avoiding touching the back by leaning on his arms and he is great shape, don't think elderly and in pain by himself...Entertainment simply non-existent and food as well... The crew were borderline okay. Plus the plane drove for about 20 minutes at Montreal and about 20 in Chicago before we left and after we landed...Let's say I saw parts of O'Hare in Chicago, I didn't even know existed!!!

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
