Flight wasn’t full

I had to re-purchase the same ticket I already bought because I missed another flight on the same itinerary, they cancelled this leg of the trip for me. Spirit will rush the planes out so they have a better on time percentage and regularly leave many passengers behind. Then you have to buy tickets again because it’s in their terms (and I believe other airlines terms too) that they cancel remaining legs if one is missed, and there’s nothing you can do about it

It got me where I needed to go, albeit with a little effort and stress. Crew was pleasant. Thank you.

6 people overbooked, who might not have gotten seats. I was one of them. I recognize there was nothing I could have done either way but it was unpleasant to hear I might not get a seat on a flight I bought a ticket to a month ago, regardless of the price. And the return flight was dismal. Had to wait an extra 3 hours for maintanence on the plane (fine, would rather it get fixed than have an issue in the air) but we were told there would be vouchers worth some amount sent to our email after we landed back in cincinnati. It's been 3 days and I have received no such vouchers. It also turns out I payed $45 for a personal bag that was I guess covered under a personal bag? I recognize this as being partly my fault, but when I went to get my ticket "personal bag" wasn't an option, so I didn't think I had one, or my single backpack actually was $45 to take with me. Was not a terrible experience. Just not a good one.

The flight was cheap

They don't even give you water. Frontier airlines is comparable to Spirit. You have to pay for everything. They don't even give you water or nuts or anything. The seats are harder than the average plane, and they do not recline. Leg room is also horrible. I have flown with them a few times and have overall had a decent experience in comparison to the low price for the flight. It gets you where you need to go with no extras.

Well the flight itself was good overall. Seats were tight but i imagine all flights like that.

Wellbi hated all the fees. For a checked bag, 35 dollars, to select your own seat 11-25 dollars, carry on 40 dollars, and nothing really special about the flight. Thought i was flying sheaper but i spent as much in bag fees as i did with the actual ticket price.

We were supposed to depart in the early morning. One and one-half hours before departure (so at the time one should already be at the airport), we received a text and an email indicating the flight was delayed. The delay was 12 hours. The flight was delayed one more time, and we finally departed 14 hours later. I asked the customer service rep about the reason for the delay, and he replied "that's a funny story." The reason was because the airline was understaffed and the crew needed to rest for 10 hours. That is not a funny story. We lost an entire day of vacation. Frontier sent by email a voucher for a small amount to be applied towards a future flight. After this terrible experience, I am very very hesitant to fly this airline again. The crew on the plane was nice. There was no flight to Denver, by the time we finally departed, we were put on a direct flight to our destination. The direct flight was nice, but we still lost an entire day of vacation. We had to rearrange all reservations and add an extra night in a hotel. The voucher in no way makes up for the loss of vacation and the extra expense in changing reservations.

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.
