The only bright spot was your great crew. First, Frontier doesn't even staff its ticket counter at MCI, so, heaven forbid there's an accident on the highway and we're a couple of minutes late, we can't even get through security. That's beyond annoying. Frontier charges for everything. For seats. For bags. For drinks. For food. So, after a haphazard boarding process and ending up in a middle seat, I flew on a lawn chair. Thankfully, it was a short flight. I enjoyed a tiny cup of water and opted not to spend $2.99 on another beverage. All of that, I knew about in advance and expected. I was thinking "at least my flight was cheap..." At the end, Southwest would have even been cheaper. I also didn't realize Frontier couldn't even be bothered by the basics. For example, opening the door when we arrived in Denver. We were on time. We waited on a gate, which is annoying, but not unusual, but then, after we pulled up to the gate, we waited ANOTHER 15-20 minutes in a roasting hot plane. JUST for someone to open the door to permit us to deplane. One of my fellow passengers quipped: "Are they going to make us pay to get off the plane?" Funny, sarcastic, but a sentiment many of your passengers shared. We finally exited the plane, and I waited on my bags--the ones I'd spent $75 to check. There was no information. No announcement. No update. The supervisor truly didn't even know what was going on. An HOUR AND A HALF later, the supervisor said, "I think your bags are still on the plane. We're short staffed, so another supervisor and I will go help unload them" Seriously? At what point did unloading bags become optional? We finally got our bags, and I'm the one who finally told the supervisor that bags from Kansas City were beginning to arrive. She announced it to the rest of the grumpy crowd. It was much worse with the cranky kids waiting on their strollers and carseats. I fly this route often. I arrived home AFTER I usually do on the much later Southwest and United flights. My fiance and I are traveling back and forth DEN-MCI/MCI-Denver often. We no longer even look at Frontier as an option when booking our tickets

The check-in process didn't work and was confusing. Every time I tried to check a bag and pay the reduced fee, the website returned me to the window asking for username and password again. I could not check-in on line and had to pay full fee for checking my bag. I was frustrated and at the airport there was no consideration for giving me the reduced fee in light of the website malfunctions by the agent checking me in. Also, the steps during the check-in was confusing - trying to sell upgrades etc, instead of just taking you thru the check-in steps.

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,
