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.

You literally have to pay for even the basic things, including for seats to recline. Cushion on seats thin and seats don't recline. 5hrs flight and No entertainment, no tv, no radio, no complimentary food...they offered a cup of water.

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.

Why would a jet this size wobble all the way across the Atlantic! The pretzels were even stale, and they served a "pizza" that was a stale mini loaf with sauce and a little mozzarella. People were starving when breakfast was served. The thermostat fluctuated from horribly hot to freeing - for 14 hrs. The crew slammed things down on table trays, grumped, were giving harsh orders to patrons rather than gently directing them. These ladies do not enjoy their job. I am done with Delta. We were also an hour late taking off due to a door on a cargo hold not closing. I was embarrassed that our Aussie friends experienced this as their first American flight.

Food, attitude of flight attendants, comfort of cabin. Pilot took charge of thermostat issue and kept us informed in a friendly manner regarding the status of our take off and flight progress.

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,
