I love Delta, especially their newer planes that have screens in the backs of headrests and free movies.

Leg room is never enough. I'm 6'1".

Our original flight was delayed and Marika, at the Delta gate of another flight to the same city, was able to get us on the flight that was going to our city. We were so grateful to get home before the winter storm! We appreciate your staff and the help their quick, efficient manner to get us on a new flight!

The layover was too short we missed our connecting flight. How did Kayak even allow us to book such an itinerary. Staff with the airline was also rude! Never will I book with site ever again!Rude

Left and arrived on time. Crew was friendly and professional.

Passengers are packed in like sardines. All carry on bags must be checked at the gate as the overhead bins are too small to accommodate anything except a small personal bag or jacket.

Delta has great seats, friendly employees and engaged managers and pilots. Even their customer service Center reaches out to help on suggestions. I am flying to Portland for School over 40 round trips and I am saving $4,000 vs Alaska Air. Plus I get miles and discounts with the Delta Amex Card. I am very pleased.

I don’t like harsh change in schedule fees but it forces me to plan. I wish the Seattle to Portland Eve flight landed in time to catch Portland Rail system at 11:50 PM

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.
