I asked for a change of seat at the gate and was given it. It really made a difference to be at the window.

Delta never used to be my first choice in airlines, but of my recent experience with them has been excellent. The people from the counter to the plane have been professional and courteous. This is why I will fly with them more frequently.

Where do i start? It’s a short flight to be sure but air canada planes never feel like many Other airlines’ mini planes or puddle jumpers. they seem new, spacious, seat back Entertainemnt, just great. Also, there is no scrimping on Service. How many Delta or united or American flights have i taken on this route only to be told “coffee or water” and sometimes no coffee “the flight is too short”. Nonsense! Granted I was in business, but I had a full hot breakfast served and a full array of beverages offered. It AC can do it, everyone can. The flight attendant was lovely.

The flight was too short :)

I love the variety of entertainment, it never fails.

I didnt like how snacks werent included for my 6 hour flght. Also the amount of waste made with all those plastic cups is astonishingly ridiculous. Switch to a more green solution!!!

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.
