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 dispatched a guitar in a hard case. It was labeled fragile and sent to a separate compartment. The guitar was poorly treated and the case was broken all over. Very disappointing. On top of that I had requested window seat and got the middle seat. No food was served and there was no movies to watch or anything, considering this was a five hour flight

For a little over $2000 you get an economy seat non-stop from DC to Tokyo and back. Meals were good. As economy seats go, it's comfortable. Midweek the flight is about half to two thirds full. So you might be able to stretch out even!

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.

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!

I have always known of airlines to offer preboarding to those military members in uniform or on official orders. Delta took it one step further and allows prior service members to board also.

Nothing was good about this airline with the exception of the baggage crew that finally helped me in Washington Ronald Regan Airport

My flight out of Portland was canceled and it took hours to rebook. I had to fly American Airline to Washington DCA where I roamed the airport at 9pm looking for someone from United. The crew in Portland ME told me the gate person would have a hotel for me.... The baggage crew had to help me.

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.

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.
