Service was awful. Delayed for more than 8hrs without an explanation of what type of maintenance issues were happening. Never given a straight answer as to what was happening. Food vouchers were only offered after the airport restaurants had closed. Once the plane was finished the crew had timed out and we could not leave till the following afternoon. Ended up being put up in a hotel for the night and lost an entire day of our weekend get away. Poor contingency planning on frontiers part. There was no reason

The crew was very friendly.

The seats were close together and not very comfortable. No entertainment, for example a movie for a 4 hour flight. You have to pay for everything. Only thing complimentary is water.

Nice flight. No issues. Flight staff was great.

Front desk check in guy in Orlando was a bit shady. Asked that we pay for our check-in bags with cash and wanted 10$ cash to put our seats together. I did not give him cash and had to ask for a reciept for the checked bags. We were 4 hours early for check in.

Customs officials are incredibly un-helpful and slow. I almost missed the next flight because of how slow was that part. I hope Delta can speak up for the passengers, because we cannot express that to these rude people.

My flight was canceled but Delta rebooked me on a flight leaving at about the same time as my original flight, which arrived just a little later than originally anticipated

Flight was fine. They were especially generous with the snacks.

My one complaint is the bathroom layout of the A320. Two tiny closet bathrooms in the back for all of coach and a much larger one much larger one first class (which is like 5 rows with a mesh curtain for separation). The coach bathrooms are so small a normal person can barely get in and turn around to close the door. I question whether a larger person would be able to actually use them. I also saw the flight attendant actively turn away coach passengers trying to use the first class bathroom when it was open (not standing in the aisle or anything annoying like that). That's ridiculous to have 2 tiny bathrooms for all of coach and also to make people walk all the way to the back of the plane when you are seated much closer to the first class bathroom.

if you have a hard engagement that you have to make, i hate to say it, but use a bigger airline. These guys are not dependable nyc -> miami. Have had 2 flights cancelled and delayed over 6 hours in the last 6 months. Only one scheduled flight everyday. If you can risk it, fine, but otherwise not worth it.

The comfort is horrible. Airline companies keep shrinking the seats and charging more. Also they keep serving less food. And flight changes.

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.
