My flight was delayed. I felt lucky when they gave me a place in a plane leaving 1 hour earlier. But that flight was delayed twice because of mechanical problems: the first time we had to go back to the gate and the second time we stayed on the runway just before take off Not enough room in overhead bins. They asked people to check small suitcase or bag.

Everything, hadn't flown since the twin towers fell, had no "real" problems in going through security and the Frontier people and equipment performed as expected.

Not a thing, I realize this is probably not normal, but it was as perfect a trip as we could've asked for.

Okay 4.3

Our San Francisco to Chicago flight only took 3 hour and 20 minutes in the air, which was nice, and the crew was perfectly fine.

Someone at Frontier is real proud of themselves for squeezing a few extra bucks out of every square foot of plane space, but after paying extra for bags (checked or carry-on), paying extra for seats, paying extra for snacks/drinks, and ending up on a plane with non-existent leg room and non-reclining, board-hard seats, we'll probably never fly Frontier again.

The original flight was scheduled for 1:25am at SFO - They then delayed it to 2:30am - Then at 2am they said they don't have a crew member available to fly the plane...so the plane sat on the tarmac and our flight got rescheduled to 9:45am and for that 8 hour flight delay, they gave us a crappy $200 flight voucher that has to be used within the next 90 days. I think public transport is better than this airline.

The “entertainment” system was more like a “frustration” system. The wi-fi was painfully slow. I had to use a different browser. Then download software. Then close a separate browser. Then download more software. At each step, I would scroll through an entire list of movies (painstakingly slowly) to get to the one I wanted, only to find that I needed to do yet another slow process before I could proceed. Finally, after 30 minutes of effort, I was watching my movie! And then 10 minutes into it, it cut off and I could not re-open it. Thanks for wasting my time and killing my soul with this “entertainment.”

Not only were my fiancé and I hit with $130 in fees for baggage, the night prior we decided to upgrade our seats to row 1 for extra leg room for an additional $90. Little did we know for that price we'd be jeopardizing the ability to reclining our seats...on a red eye flight. I'm incredibly disappointed in frontier. I use to fly them frequently to/from SFO to the Midwest and the quality of service has decreased tremendously! These additional fees you tack on are taking advantage of customers and unethical.

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.
