Okay 5.3

Pros: Excellent crew, very friendly. Timely boarding and takeoff, early landing. The price was great, although if you expect any basics, like picking your seat, or a carry on, or a drink, that price becomes far less competitive.

Cons: Frontier is the most uncomfortable plane you will fly. They are glorified lawn chairs. Zero leg room, chairs don’t recline. Unforgivingly hard plastic and non-ergonomic seats will hurt your back and butt after 15 minutes.

Pros: Boarding the plane, getting off the plane, and the actual flight were all pleasant.

Cons: Frontier’s automated system message regarding the cost of checking in bags/paying for a carry-on bag counterdicted what the actual cost was. I’m just glad we looked into it before getting to the airport, otherwise we would’ve been stuck with their high fees to have a carry-on. We spoke to their main office, but the price quoted on their automated system was never honored. This is my first experience with Frontier, and my last. I’ve never been on a plane and been charged almost $3 for a very small cup of soda and a snack—for other airlines, this has been complimentary, regardless of the distance traveled. Their low fares aren’t worth the extra cost of carry-on luggage and a small sip of something to quench my thirst for a couple of hours.

Excellent 10.0

Pros: My daughter forgot to mention I have a disability when booking flight. I went to boarding desk and they got me on flight right away!! I will fly frontier as much as possible in the future.

Cons: Space a little tight but my flight was only 2 hours so I could live with that. Would love option of an entrainment unit on seat backs but I understand that with cheap flights it wouldn’t be cost effective for frontier. Flight delayed but that happens a lot with other airlines. Gave regular updates at desk and reason for the delay. Staff wonderful. Plane spotless

Pros: It was a light flight, so I could have my carry-on with me even though I was in group 5. The breakfast -- berry pecan French toast -- was surprisingly tasty and satisfying (if not very attractively presented).

Cons: Too bad I had to pay so much for the exit row seat. I'm tall and it's needed for standard comfort (as opposed to extra comfort). Oh well. Gotta squeeze those dollars out of the passengers every way they can.

Pros: The flight crew were absolutely marvelous and were wonderful on board.

Cons: British Airways had too tight of connections on flights that we purchased and then they ran late. Because of this, we had to rebook both going to Europe and coming back. Our friends were then charged extra luggage fees when being put on a domestic flight back home after going through customs. It will be difficult for me to want to use British Airways again because of all the flight change notifications we got before traveling and then once we did actual travel.

Pros: The films available were okay, but we had to watch them on our phones.

Cons: Moved our gate twice, both times the AA boarding crew laughed at the anger they’d caused among the upset passengers. They were also not vocal about the gate changes until pressed. We were asked to sit by the emergency gate as able and willing humans unaware it was placed beside the center bathroom.. so unpleasant.

If you know a large number of your passengers are coming in on a flight from the east coast that was delayed for de-icing...wouldn't it be easier to just hold the flight, since it is the last flight of the night.

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.
