Once we hit the coast we skirted down the coas of Florida which provided a spectacular view. The approach and landing at Key West airport was thrilling and absolutely perfect. We’ve flown Delta many times but this was our first but not last time to Key West.

Mediocre 3.3

The flight staff of my flight to Amsterdam were horrendous. I was in an aisle seat and was woken up by the drink cart hitting my leg and a hot coffee being poured a good 7 inches from my face. This was not acknowledged or apologetic. They also took drink orders by shouting. They were easily the loudest people on the plane and made the flight way less comfortable than it could have been.

Flight attendant from IND to Minneapolis must have had a rough evening or bad morning. Service in airplane is usually poor but this one was worse. Bumping most of the passenger when passing, handing drinks behind his back, not smiling.

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.
