Mediocre 2.0

Pros: That it was cheap when we booked it online.

Cons: Apparently it wasn’t that cheap of a flight after all. We had to pay for our luggage instead of a carry on. And the plane was empty not full with passengers. That to us was a ripoff. Don’t Deceive passengers to fly cheap with you when you’ll make them pay you for carry on when it’s not needed.

Excellent 8.0

Pros: The crew was lovely and friendly, very pleasant to fly with.

Cons: Not a fan that I was seated between 2 men I did not know which made me uncomfortable enough that I couldn't sleep at all during my red eye.

Good 7.0

Pros: Comfort+ seats are affordable and give me the leg room I need as a 6'3" adult.

Cons: Seems like Delta provided free upgrades to families with small children in Comfort+. This impacts the flight comfort for us paying customers. Recommend readdressing this policy and not placing small crying children in Comfort+ for free.

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.
