Seats are clean. Cabin looks new.

Seats are very narrow. Anyone slightly overweight will be spilling over into someone else's seat. The design was not made with the average person's comfort in mind.

Had a reasonable seat for not paying extra for it. Flight took 2 1/2 hours instead of 3 which was too much to start with. Smooth flight the entire way.

I knew this was an expensive flight so I should have no complaints.

Would like option to add carry on during ticket purchase. Did not see this when I booked so had to pay extra upon arrival. If it’s there is easily missed.

Accident on way to airport, so I showed up to check bags 45 minutes before flight time. They said they couldn't get the bag to the plane..in 45 minutes? So, they put on the next flight... 6 hours later. Said I could fly without the bag... uh, no thanks. They would not look for alternatives without charging me more. Flight attendants were crabby, otherwise everything was fine. I flew British Airways a few months ago. Night and day. Seriously. Delta does not even approach having good service. There was no comparison to British Air--- Delta is not in the same league.

Plane arrived early

They board the front of the plane first, meaning the aisles get clogged up slowing down the process. Also, staff kept insisting pre boarding that more people needed to check their bags because there wasn't enough overhead bin space, but there were plenty of bins not full by take off.

There was a change in our flight. According to Delta you didn't confirm every leg of our flight and the plane was over booked.

On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you.

On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra.

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.

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.
