The seats are too narrow, which I can tolerate for about an hour.

I made the reservation without knowing that Americans airlines has a boarding number 9 where you are NOT allowed any carry on. Awful lesson. You are given the worst seat and you cannot store any thing in the overhead compartment. Or there make you pay $60..

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
