I didn't go on my trip. My course in SF was cancelled and United would n't refund my money or change the dates for my trips because of there basic economy package. They have 3 different economy packages and the economy basic doesn't get refunds and you can't change the flights if needed. It feels like they are banking on increasing there ROI with this basic economy ticket which is 40 -60 dollars cheaper than the next economy package. Intuitively they know people will pick that, but if something comes up the customer is screwed.

Everything ran smoothly on this flight. No delays before, pleasant staff, great entertainment selection, okay food options, working equipment (e.g., tv in the headrest worked, seatbelts worked, lavatories were operational, etc.). This flight met all my expectations

The only hiccup was the wait time on the runway before take off. Not sure if that was the airport’s fault or the airline’s fault. We must have waited 45 minutes.

Nice flight with competent crew.

Kiosks did not work for check-in so I had to queue up and wait for help. Then I got charged $45 for a carry-on. Not a great start to the day.

I didn’t like anything about it.

I almost missed my flight because you oversold . Your agent at the gate wasn’t friendly at all. I had to call the customer service so I get my seat.

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.

Fairly inexpensiveI

I did not like the fact that I was charged $45 for a carry on piece of luggage both ways. It added $90 to the cost of my trip.

Website would not let me check in the day before or the morning or my flight. There was an error every time and I almost got to the end once. I could not change the time of my transportation and arrived 10 minutes past the check in deadline (an hour prior to the flight taking off). I was refused access to the flight and offered a flight 5 hours later. The staff was rude and not helpful. I had heard negative things about Frontier and now I know why.

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.
