This is my 3rd delta flight in a row that has been delayed. I understand these things happen, just extremely frustrating.

The Delta flight was such a pleasant contrast to the funky Interjet flight that I took from L.A. to Mexico that my Economy Class felt like First Class.

Was unable to board an earlier flight without paying $75. If there are seats it shouldn't be so difficult to be moved.

This plane was awful. I don't know how anyone who is not miniature sized could be comfortable on this plane. I am 6' 1" and ~ 200 lbs, not huge by any means, but not tiny. I legitimately could not stand up (so I had to sort of slouch walk down the aisle to find my seat at the back of the plane), then the seats themselves were so narrow that I ached terribly when seated in any position for more than acouple of minutes.

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,
