I worried about flying in a turbo prop plane but the flight was supriseingly pleasent. Seats were comfortable.

I didn't like having to pay extra to pick my seat assignment but I understand that was only for the lower priced leg as there was no ectra fee for the "flexable" return leg.

Unable to fly to Toronto. For anyone that does not have a Canadian passport, an electronic Travel Authorization needs to be completed when flying to Canada. As I was not aware of this form that needed to be completed prior to my travel I was not able to take the plane.

I reached the airport and on being checked at the counter, I was told that I cannot board because I don't have a Canadian visa. It was shocking to learn that I needed visa for a 1.5 hour layover.

My United connecting flight was delayed. I rushed to arrive at the gate prior to the departure time to be told the plane had left early and I had been rescheduled to the next morning at 7am. However, there were no vouchers available for me to stay in a hotel or get food. So, I was able to get a flight on American that got me home the same night. By the way, the American flight was delaying takeoff to wait for passengers who had been delayed on their connecting flights.

No kiosks to check in. You have to check in at the counter, but if you check in early online you still have to check in at the gate.

Nothing - they were immature, unprofessional, nervous, unhelpful, and visibly shaken by relatively side problems.

The flight was delayed for hours but not technically cancelled, which the ground crew blamed upon the flight crew and vice versa. The failure to cancel caused us to be unable to rebook, and subsequent avoidable delays arising from Air Canada's ineptitude caused us to be two,days late for arrival. The problem was solvable with some simple rebooking, but the ground,crew failed to assist, then the flight crew, when we finally left five hours late, was Impersonable, unhelpful, uninformed, and utterly unprepared. It was a terrible, second rate, poor quality experience and I would not recommend Air Canada to anyone. Your airline needs serious training in Professionalism and responsiveness.

The ground crew were always nice and friendly. They worked hard to deal with delayed flight, missed connection, and tight alternate connection. Flight crew were also friendly and helpful.

Four-hour flight delay released in one hour increments without announcement -gate displayed "on time departure" for the duration of the delay. Our hassles were compensated with meager meal vouchers given too late, There was no pre-boarding on our flight (just one big cattle call) which made boarding with child and gear extra awkward,

They took like... whole day to book another flight. And i had hard time understanding what they were saying.

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.
