They changed my flight to a different one departing 2 hours earlier and did not notify me! The original flight was still available & they would not let me take it despite my reservation paper work. CRAZY! I have a two hour drive to the airport this gave me the option to leave home at 2:30am or go the night before and pay for a hotel. Flight was managed by DELTA who also did not care! All involved blamed each other. Beware

The boarding went quickly and was well organized

That the price to take a small carryon was just as expensive as taking a large suitcase, ended up having to pay and extra $80 r/t for a small bag and I just that's standard for them. There were no barf bags in any seats, believe me everyone around us was looking as the person next to me was getting sick on the landing because it was crazy rough. When we finally were able to get an attendant over she was as rude as could be, I'm sure this sick person next to me was sorry she "inconvenienced" the crew member, if they just put bags in the seats pockets like every other airline this wouldn't have been an issue. The seats were very uncomfortable with no padding and not able to tilt. The tray tables were nonfunctional, too small and did not extend to get anywhere close enough to reach you. The plane ride itself felt like we were on a old school bus on a gravel road. I had a round trip ticket with frontier and both trips were equally as bad. I will never travel with them again, Most of us weren't even sure if we were going to survive take off with out the plan breaking or something.

Seats were comfortable, but much too crowded. The seating would have been very good for children but for adults it was much too crowded. My knees were up against the seat in front and my back is sore from having to spend most of the trip twisted to try to fit into the small space. Also, my seat was is row 16 and was called a “premium” seat and I was charged an extra $24 for it. I did not find it any different than all the seats around me. What was the extra charge for?

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.
