The fact that the in-flight meal was as cold as the crew, and you got to pay for that coldness. Just love it! You get me right?

The Montreal-Vancouver route was by far the worst. The attitude of the crew was denigrating and arrogant.

I had an episode of anxiety over very minor turbulence which I sometimes get and both ladies who happened to be on duty were very reassuring and sympathetic to me. I had my 6 year old daughter also on the plane who is not anxious at all, so I was able to speak to one of the staff in French so as not to transfer my anxiety to my daughter who doesn't understand French. This was great. Over half way through the flight they gave me some earphones and suggested I watch a movie. This helped so much.

That it got me to Paris safe

No outlets to charge your phone, and the tv played the same movie over and over. The meals were also cheap. Didn't like any of them. Should have flown southwest or delta.

The seats were incredibly uncomfortable! Also, many people did not understand how to turn off the televisions, so it was pretty distracting to have so many monitors going when we all trying to sleep.

Flight back was OK but flight to Orlando was not. Travelling with s 94 yr old man in a wheelchair. Everything at Pearson is not conduscent to travel with a handicapped person. Poor layout, poor assistance, non caring people, long distances,, and final straw was air canada started boarding without calling for handicapped first. We had to stop them and then fight our way up the aisle with people all in the way. Terrible, just lousey. 3 and a half hours before flight we arrived and didn't even have a chance to get some lunch before flight. I give Toronto and air Canada the worst possible rating of any airport or airline I've ever dealt with. John O"Hearn

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,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
