We had issues with baggage. Delta was supposed to transfer 4 bags to Disney for Magic Express transportation. Only 3 went. Disney tried hard to fix problem, and even gave us something to ameliorate the situation. Delta took hard line, wasn't helpful and gave nothing. It took 2 days to find bag.

The flight crew was incredibly sweet and helpful; one of them even gave me their personal TUMS when I said I didn't feel well.

The flight boarded 30 minutes early; I arrived to my gate at the time of when my ticket said boarding started, but they were already calling final boarding call for my flight. I completely panicked. The plane was clean but the seats are very close together and there were no complimentary snacks- even though it was a 6 hour flight. On my flight back from Seattle on Delta, we got a complimentary meal AND a complimentary snack. I was expecting my Alaskan flight to be better based on everything I'd heard from friends, but my return Delta flight showed Alaska up; it was a spacier plane with way more food offered.

I am used to flying Frontier because of cost but recently traveled Delta and boy did I feel completely spoiled! Not only did my other half get our bags for free due to his status with Delta but the amenities they offer and the comfort of the economy seats compared to other airlines is a major difference. As a chronic pain patient, if I can find a Delta flight for a little more, I will be booking with them for sure! Highly recommend them!

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.

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.
