The crew has a good vibe, makes for a pleasant trip

First time for me to have delayed baggage, made me think that somebody is not minding the store.

Okay 5.0

The gentleman at the gate was super helpful and helped us check our bags at the gate.

Zero leg room. Zero arm room. The entertainment system did not function. No food for such a long flight unless you pay more then the food is actually worth.

Excellent 9.0

Entertainment and crew were great- comfortable seats, got to watch a couple of movies with headphones provided by Delta; forgot mine so I assumed I would be miserable thru the whole 4 hour flight. so glad I was wrong! Would definitely take another flight with Delta... looking into the frequent flyer program as we speak

Flight crew was good, we arrived early on flight out and back! Feel like seats are tinier than ever, maybe it was just me. Food (water & pretzels) were OK, but nothing special (then again it was a short flight, so I didn't expect anything). Plane was small so we needed to gate check bags and the gate attendant came around and tagged everyone's bag for us, well before boarding which was hugely efficient - kudos to her on that!

Gate attendant's mic was broken (or she didn't know how to use) so she had to yell into the boarding area.

The flight attendant named Steven went so far beyond the call. He was attentive, he fixed our video system when no one else could and when he learned we were celebrating an anniversary he brought us a present. He was awesome!

The fact they wasted two days of my trip with my son travelling from the U.S. to China because they didn't know about transit visa regulations. And so far they offered a 75 dollar voucher for participating merchants. Unacceptable

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.
