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".

Quick boarding, clean plane, good entertainment system.

Used a neck/back pillow and jacket against hull to try and keep my shoulder and arm from freezing solid. I usually sit by the window on a couple dozen flights per year, and it has never been this cold on my arm. I wonder if a heating pad would work on their outlet?

Delta seats are comfortable and media ststem is good.

Flight was late and the staff wasn't kind Neither at JFK gate neither on both flights. Looks like they are doing you a favor to listen to you when you ask them something.

Punctual departures. Adequate overheard space.

Food was mediocre for a 5-6 hour flight. I expected a little bit more.

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 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.

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.
