The plane took off over an hr late due to lack of heat and the pilot had to reboot the system, once the plane finally took off the flught attendsnts then explained they would start the beverage service but were iut of most options and we could get ready to pay for what was left, maybe if they offered complimentary beverages at that point would've been a nice touch.

They gave me and someone else the same seat luckily it wasn’t a packed flight and was able to move to a row that was empty

Not much.

Where do I start. Ticket counter at check in is an abomination even if you did it online as they suggest. The airline groups together those needing check in and those dropping off bags which makes no sense at all. Results in a long process. Nickel and dime you until the savings from a traditional airline is non-existent. Seats are uncomfortable, crew is unpleasant. No wifi or entertainment. And baggage is always delayed. Pay the money for a regular airline.

There's no "complimentary" snacks on Frontier. Which is fine, their flights are cheap and comfortable and the snacks are affordable. I also don't really appreciate having to pay for a carry on. I knew about this so made sure my bag would be considered a personal item, but I just don't know how I feel about that as a backpack may not even fit under that seat. But again, the flight was cheap. So, I don't know.

I really liked having two kids punching my seat every 5 mins on a 3 hour long flight. Pilots do know how to take off and land so I'm alive and that's the best part I liked about my flight.

Seats are terrible. I know it's not the international flight but please please hire more attractive flight attendants. I don't want to have nightmares.

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.
