In some Delta flights that I had in the past the plane was just ok, not bad, not good. But this plane ATL-MEX was great, very nice and conformable plane, it looks and feels excellent!

The flight was on-time. Crew regularly provided water during the long trip.

I ordered a vegetarian special meal online, but when the crew got to my aisle, all the vegetarian meals were taken! I do eat dairy, so it was no problem. But, it would not be fair if they ran out of that too for customers who have specified vegetarian online ahead of time.

I was on a business trip and needed internet during this 10 hr flight from London to San Fran. Paid 40 bucks for internet and got abt 15 minutes of it. Extremely frustrating. Flight attendants bewildered about what to do about it.

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,
