Pros: The plane was nice and the entertainment on the flight was great! Flight crew very friendly.

Cons: Our plane was delayed multiple times and we were not provided an explanation as to why. For as expensive as this fare was the fact that Delta was at fault for the delay and did not offer any compensation for that delay is frustrating. A few extra free snacks doesn’t cut it.

Okay 4.3

Pros: Despite boarding late, and sitting on the tarmac for half an hour since we missed our take off time, and having to move passengers around to balance the weight on the plane, we made it home alive.

Cons: We landed over half an hour late. Flight attendants needed to move passengers to balance the weight on the small plane, and asked for "volunteers." When there were none, the FA stood in the aisle and said we just weren't going to take off if nobody volunteered. They should have just MOVED people.

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,
