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.

Friendly staff, quick to get on the plane after a long wait in the security line. TSA is very inefficient in SAN.

The cabin crew didn’t let us know we got free drinks on the premium seating area. Hey should invite us proactively to order our drinks. The menu does not contain info on what is included on the premium seating purchased. The seats are too narrow.

We were separated...we had to try to negotiate with other passengers to trade seats so we could sit as a family. We purchased our tickets 4 months in advance, there’s no reason for us to not be sitting together!!!

Getting to where I needed to go

Stopping the plane to fuel at another airport understandable. But then you ran out of food for purchase on the first flight (I was sitting in the back). Then connecting at LAX was horrible. Everyone had connecting flights. Off the plane onto a bus. then through customs then shuffled outside with no guidance from employees. Finally I found someone to ask bc 15-20 people were around me in the same boat. Where the f do we go we wondered. The employee was insanely rude. I’m attentive and I listen. he was saying pay attention I told you go right blah blah blah. He was literally standing there with his arm out pointing right and never said a word to anyone. So once we figured out to go outside and right we had a stressful ten minute wal hoping we were going the right way. We were! We get to tsa and have to go through screening again. Which is insane bc we just got off a plane. The tsa agent told us this happens everyday with a smerk. On top of her attitude, her and the two other lazy ladies on her line were painfully slow. The other two lines went at least twice as fast(no exaggeration!) made it to gate 66 to find it was changed without notice to 63. Made the flight by two minutes or less sweating from running around!

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).

Good 6.0

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.

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.

Mediocre 3.0

Not to much

Was like riding a city bus. Even in row one didn't have much room to stretch out. Check in took awhile. Only thing they had going for them was good pilots and staff. But the planes are trash no entertainment, little selection of food and drinks. Don't suggest at all.

Mediocre 2.0

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,
