The crew is really nice, attentive, and it's not hard to get their attention. They also don't bother you when you sleep and are overall quiet and courteous.

Not knowing how long until we land. A quick "1 hour till arrival . . . 30min..." would have been appreciated.

The price of the flight was great, but even with an upgraded seat I will not be flying Frontier again.

I upgraded my girlfriend and I to stretch seating for our 5 hour flights roundtrip from ATL to SFO. I did not realize by upgrading and selecting my seat in row 4 that my seats do not recline. This caused several issues with my bad back and with the fold down tray on the seat in front of me. I had my laptop on the tray, and when the person in front of me leaned his seat back all the way suddenly, it pinched the top of the screen between the tray and the back of his seat and cracked my laptop exterior. The main issue was not being able to "stretch" by not having a reclining seat and experienced major discomfort and back pain both flights.

The plane was clean and we left on time with no delays or issues. The flight crew were very nice and there was also enough overhead space for everyone’s bags.

The lines are excessively long to check a bag, there was only 1 of 4 check in kiosks working, which created it’s own line. Also the carry on bag fee at the airport was incredibly steep.

I flew economy. We left the gate on time, the seat was comfortable, entertainment was varied, flight attendants that I came in contact with were professional and pleasant, food was hot and very good, pilots got me where I wanted to go, and that little container of ice cream - oh I love it! The plane was not completely full, which made the seating more comfortable than it would have been if the plane was full.

I was ushered into what became a very slow line to board. The employee at the end of my line had to deal with a few problems so I ended up boarding close to the end, behind those with higher group boarding numbers than I. Having a single line up to the two boarding employees, would avoid that, albeit make a longer line to begin with.

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.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
