I read that everything was ala carte on Spirit Airlines, so I knew to pay for my bag online and carry on only the size allowed for free. The boarding and flight was very smooth. There are kiosks at the airport to print your boarding pass which also saves you money.

I didn't understand how to pay for a beverage/snack while on board the plane. Wish that something that inexpensive would be offered without charge!

I tried to find out who checked me into the flight and her supervisor. I was discriminated against for having a service animal. I was told my doctors paperwork was insufficient. I called spirit airlines to see who was working and they could not find out. I will never fly again with spirit.

There was no complimentary drinks or snacks for a 4 hour flight....also a checked bag was 38-45 dollars!! Other airlines were as cheap as 20 dollars. The seats were very close together, no phone chargers, no tvs, no headphones, nothing! Honestly I would not fly with frontier again.

The only thing I didn't care for was that when my flight was delayed by three hours; when I landed the crew in the airport because an attendant refused to take minute to look at my ticket. If she had looked at my ticket she would have seen that I didn't miss my connecting flight because it was also delayed by three hours. I almost missed my connecting flight because this artentand kept refusing to help me and kept sending me to customer service who would have told me to get on my same connecting flight. The attendant was working at the desk near my connecting flight but refused to take a minute to try to help me even though she wasn't busy nor was she helping someone. I had to figure this out on my own while standing in line at customer service, which had about 100 people waiting who also missed their flight so I would have missed my flight if I had done what the frontier attendant from my connecting flight desk had instructed me to do. I had to run back to the gate minutes before boarding ended almost missing my connecting flight because of the attendant. Attendant worked at the denver , co airport. The crew on the plane and everyone else was great. Also didn't care for the charge for a carry on bag.

Frontier changed our flights and didn't notify us and left us high and dry in Philly yesterday!! Thank God for my sister and travel insurance otherwise I would have lost my mind.

They took our money, a lot of money and then stranded us in Philly, then gave us the gift of a 13 hour layover in Denver. Frontier is the WORST AIRLINE on the ENTIRE PLANET!!

This is actually almost a funny question because Frontier is the worst Airlines well actually that's not true spirit is the worst Airlines the seats are uncomfortable it takes about an hour and a half to just put your bags and baggage drop and then when you get on the plane They don't serve you anything they have no entertainment your crowded in can't move people are rude worst hairlines ever

Frontier changed our flights and didn't notify us and left us high and dry in Philly yesterday!! Thank God for my sister and travel insurance otherwise I would have lost my mind.

They took our money, a lot of money and then stranded us in Philly, then gave us the gift of a 13 hour layover in Denver. Frontier is the WORST AIRLINE on the ENTIRE PLANET!!

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.
