The breakfast on the international flight was pretty good. However, there were more frequent snacks and healthier options when I flew internationally on Delta.

I didn’t like that my pre-flight request for gluten-free snacks/meals was ignored. I didn’t like the attitude of one flight attendant who couldn’t bring herself to empathize with my allergy to gluten— which causes painful cracks in my palms and fingers.

The crew was very nice

It was a short flight. Didn’t dislike anything other than paying for TV/movies.

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.
