Pros: Nothing

Cons: How about maybe a course in customer service ? If I have a question about what’s going on with a flight I paid for, getting shoed away like an infant asking for a toy is ignorant. This is why I never fly this airline unless absolutely necessary. Porter is always ignorant and unpleasant

Pros: Our flight attendant was WONDERFUL! I wish I knew her name. She was the only one with glasses. This was the ~3:15pm flight Nov 25 from Montreal to Toronto. She was very pleasant and attentive, and truly loved her job but not over the top. My friend and I were super impressed by the service of everyone but especially her. The snacks were also a very nice touch. Great prices and deals on flights

Okay 5.0

Pros: Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines.

Cons: Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA.

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

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.
