The flight was canceled very close to departure time and I was bumped to a flight leaving five hours later. Missed my train connection in Montreal and had to rent a car and drive to Quebec. Since I go to Canada only rarely, I ended up essentially losing the money I spent for train fare and having to pay another $145 for the rental car. Got to Quebec at 11:30 p.m. instead of 3:55 p.m. Not happy.

The earlier flight departure times are really good, the traffic is not jammed yet on the 401 and GEW. Custom waiting times are basically non existing in comparison to Pearson. Planes are relatively on time (only flew 4 times with Porte), staff is friendly. The turboprop planes have more legroom than most others. I do like them, and do recommend Porter.

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.
