The one thing I liked was the expedited service I got because my brother needed a wheelchair. The comfort of the plane was really nice as well, one of the best flights I had in a while.

What I didn’t like was how my flight got cancelled and the only flight I was able to get was 4 days later. So I was stuck in the Dominican Republic for a total of two weeks!! I had to miss another weekend at work which made me lose a lot of money since I’m a barber and lost some one my clientele. On top of my flight being cancelled it also got delayed again but only by 30 minutes so I wasn’t so upset. When it came to the boarding, that had to be the slowest boarding I’ve went through. The gate seemed very behind on the technology and that caused the workers to work even slower. At times they had to step away and go on their monitor to fix something out so it took an extra 30 minutes before I even got into my seat, and I was sitting in row 6 of the plane. Then after everyone was seated the flight got held back an extra half hour because a lady wanted to file a complaint saying that she got pushed and ended up being the only person that got kicked off the flight so she did it all for nothing. So with everything happening, our flight got delayed an hour and a half. Very disappointed..

The flight was late due to maintenance and caused us to miss our connecting flight to Chicago. American Airlines customer assistance at the airport was absolutely terrible. They were rude and inconsiderate as they kept suggesting to fly standby. We shouldn't have to fly standby when it wasn't our fault why were late. They told us our bags would be ok going to Chicago and they we would make the flight, but we did not. I do not know why didn't wait for us considering there were 8 others that also missed the connecting flight. We had to fly to Denver and stay overnight with no luggage and catch a 7:00am flight to Chicago. The last surprise I received was my damaged bag when I got back to Chicago. Thank you for making this trip memorable in a terrible way. I will never book or recommend Kayak or use American Airlines again.

Every single employee I interacted with was awesome.

Over 5 hours in delay due to a maintenance issue. Problem wasn't discovered overnight when it was parked. Wasn't discovered until the next day. Had to wait for the delivery of a specific part and install it. I'm all for planes not breaking upon reentry, but the fact that the two flights were both subsequently delayed 4-5 hours each instead of bringing in a sub plane was inconsiderate. Now I've got a long drive home and I'll only get an hour of sleep before a 14-hour work day. So thanks for that, JetBlue

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,
