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.

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..

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!

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

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.

The crew was nice, quick check ins and boarding. They were very accommodating during the flight.

Although it was breakfast, not everyone wants sausage or the other option of fruit and yogurt. Meals should be offered in the literature provided by time, as in reality, if you're not going to sever the expansive US menu throughout the day. I was unable to order a salad at 9 am, regardless of being starving. Also I'm 5'1, there isn't enough leg room. Power outlets should not be a first class luxury, that is rediculous. We all need to charge our devices. TV should not come as an extra charge.

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?

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.
