My flight was 2.5 hours late due to gate availability. Does Frontier have access to only one gate at SFO? Once I got to the airport, I learned of a 1.75 hr delay due to fog in SFO earlier in the day effecting gate availability. So instead of landing at 11:30 pm, we landed at 1:10. A plane was still occupying our gate so we had to wait until 2 am before we could get off the plane. I will only fly Frontier in the future when the cost is much less than other options.

Easy boarding and exiting. Plenty of overhead space. Traveled with one personal bag to eliminate baggage fees. Online booking clearly stated cheaper to pay for carry on bag during booking. Cost higher at boarding. I appreciated the lowest ticket I could find. Seats firm but new and comfortable.

All around a pretty good flight. I did not miss the bag of nuts

The crew was great and made the smart and thoughtful decision to allow us to unboard and reboard the plane after it was announced that the wheels would need changing and would take 1.5 hours

Major delays meant we were 2 hours behind schedule. These things happen.

The airplane was clean.

The seats were not reclinable and for a 3.5 hour flight in which I wanted to get in some sleep I was unable to sleep. Also the seats were very narrow and with almost no padding. I could feel the padding had wore off and my back was touching with the metal of the seat. Add all that up together and instead of a regular airplane seat it was like seating on a rigid chair for 3.5 hours. Moreover, since I couldn't sleep I decided to at least get in some work, but then I realized that the tray was so tiny that it can't even fit the smallest of laptops... I know it is a low cost airline, but paying for carry ons, checked bags, selecting seats and on flight beverages is plenty for a low cost airline. Frontier doesn't need to top it off with the most new uncomfortable seats possible. At least with Ryanair the seats are more comfortable, you can bring a carry on at no cost and the flight ticket is cheaper.

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,
