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!!!

The crew were professional

The worst thing is that they schedule a CRJ-70 on this flight. This would be tolerable if the obvious alternative was a turboprop, as if Montreal were a small town, like Flin Flon. But it is not; it is a large and important city, and it stinks that the demand is so low that airlines must use small aircraft on these routes. Is it because Canadian taxes are so high on airlines that fares in turn must be high and not stimulate demand? I can't think of any other reason connecting cities this size would be on crappy little aircraft rather than on at least an A320/737 family aircraft. The problem is that there is not enough room in the overhead bins to fit rollaboards, even small ones like mine. So they have to "gate check" the bag, which does not always reappear at the gate at the destination. Less bad than the choice of aircraft was the fact that after we pushed back, they couldn't get an engine started, so they cancelled the flight and reaccommodated us on a later flight.

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...

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.
