Pros: Boarded quickly and got in early

Mediocre 2.0

Cons: Flight was delayed by almost two hours so I missed the flight from Denver to Charlotte. Because of the way this flight was sold to us and booked through Kiwi.com, there was nothing that could be done to get me on another flight. The only option was to wait for a Frontier flight which wasn't available until Monday morning. I had to book another flight on a different airline at a cost of $600.

Good 6.3

Pros: We were able to fly standby on our original 2:30p flight but had to return to DCA for checked baggages later that day

Cons: Connecting flight from JFK to DCA was moved from approx 2:30p to nearly 8p, making our layover 7+ hours, as opposed to 1-2 hours. No reason for this change was provided. Delta crew member in JFK was rude and unhelpful. The second agent (who ultimately booked our standby tickets for our original connecting flight) was more pleasant.

Pros: Our flights arrived just in time, and everything was set up for us to be on time in our destination.

Cons: There was just ONE lady trying to check all the passengers in. Obviously, it was complicated for her since no other people tried to help her registrate lots of passengers. We could have lost our connection flight, if she hadn’t made it on time. This happened in Panama.

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.
