Three hours delay. I paid for a upgrade to first class. But because of the flight change i didn't get to keep my upgrade and I had to beg for a refund. I have had two trips in the past 5 days and all flights have been anywhere from 1 to 3 hours late. Worst experience with AA I have had in a long time.

The crew was rude to the passengers. They charge form 9$ to 40$ for seat selection. Charge for a Carry on bag (anything that doesn't fit under your seat). The flights had maintenance issue, hence delayed. I will absolutely avoid traveling with frontier in the future.

The flight was ok

First of all the check in lady was rude and unprofessional. The company lost y luggage resulting in extra charges When I was looking for assistance mr Prince was extremely rude, rolling the eyes and not providing support, I was lost and seeking for guidance and I had to figure it out by myself

Great flight from Islip to MIA. Looked at another review about water on flights and I was told by the crew that water is FREE!

Seats are small but newly redesigned.

Mediocre 3.6

The crew was helpful and apologetic.

They purposefully understaffed the check in counter, which you have to use. They charge for every little thing, even carry on bags and snacks. The seats might as well be lawn chairs. They are so close together everyone onboard will die from head injuries if there's an accident. I'll fly Southwest from now on.

The crew was friendly and informative. They were very helpful. The

The seats were uncomfortable. They were hard and so narrow I had to sit crooked in the seat to keep from getting banged into by the service carts and every person going by to the bathrooms. I'm not tiny, but I'm not huge either, it was just overcrowded. It was also very hot in the airplane the entire way from Phoenix to Spokane. My husband, who is always cold, was even hot.

The free in-flight entertainment was great. I appreciate it being free as it makes up for some of the other issues of not being able to sit next to fellow travelers on the low-fare

Did not like that on the low-fare I could not choose a seat next to my traveler. This made me ask the person next to my wife if they would like to switch, which they nicely did. But I imagine this asking of switching seats will probably create tension for your customers in the future. You might consider going back to the original model of sitting next to your fellow travelers.

Direct flight from desired origin to destination Boarding by zones

Uncomfortable, small, seat space with inadequate legroom. Lack of personal entertainment options. Paid extra for earlier boarding group which only benefited me by about 5 people. (NOT WORTH IT!) Lack of complimentary food options. (Pay for everything)

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,
