Pros: Sat by united pilot who was just on flight to go to training and was with my 10 mo old daughter and was absolutley wonderful, so helpful and Im sure it was not an ideal situation for him. On second flight we sat next to flight attendant and a trainee and made our first flight trip... that could have been awful great! Big thanks to all the staff.

Cons: Two rows up from us, I kid threw up all over the center aisle as we were pulling away from the gate. We returned to the gate to allow a cleaning crew to board and clean. However, the cleaning job was rushed and left remnants of the throw up behind which smelled the whole 2.5 hour flight. It really felt unsanitary and unsafe being that it’s unknown what caused the child to get sick. It very well could have been a stomach virus and could have infected the people in rows around the incident due to the mediocre cleaning job. I understand that it’s important to keep flights on-time, especially for connecting flights, but the safety of the passengers and their health should ALWAYS be the #1 priority.

Could not get comfortable so could not sleep. Most of the crew were friendly and courteous, but was the 1 who was less so. Wifi quit

Cons: The airline charges extra for things that most airlines provide as part of the ticket price. The ticket was not cheaper than other airlines to compensate for the additional charges: carry-on fees, choosing a seat, snacks and beverages, etc. We were delayed with no explanation; it's nice to be kept informed when that happens. Crew was fine but I won't choose Frontier again because of the additional charges for things that should be included in a competitive ticket price.

Mediocre 2.0

Pros: Literally nothing.

Cons: I charged the airfare, thinking that would be all, like other airlines. Then I found out they charge for luggage. THEN I found out they charge me for a seat... on the flight I already paid for. Boarding was disorganized, seats were thin padding on plastic, quite uncomfortable. I also had to clean crumbs and trash off my seat before settling in. They charge you 2.99 each for water and airline peanuts; i didn't partake. they only gave me one boarding pass and when I boarded the plane, they said that is was the flight to Denver and then they were continuing on to Columbus. I assumed this meant I stayed on the plane when we landed in Denver, but no, they informed me the plane was then going to Cedar Rapids. I had no second boarding pass or gate number, so I asked the attendant. She took forever to help me, looking up my info for a minute and then talking to the other attendants and passing out papers to the boarding crew before acknowledging me again. Twenty minutes later, I had my gate, which I barely made to board in time for flight takeoff. Overall, the process was stressful, uncomfortable, and more expensive than if I had purchased a flight from Delta, Southwest, or Alaska. (All airlines I have flown and been happy with. Delta had a missed layover once and completely put me up for the night and was very helpful through the whole affair.) All said and done, I will not be flying Frontier again.

I also didn't like the fact that I had to buy Economy Plus because my wife and I were not only not assigned seats together after booking, we were not assigned seats at all. When I booked the flights I was only allowed to choose seats for the first flight - Charlotte to Houston...but not for the other three legs of our Charlotte to Seattle trip. The only two seats together from Houston to Seattle were in the very last row. And, on our return flight we had to purchase Economy Plus in order to sit together.

Mediocre 2.0

Pros: Everything but…

Cons: You lost my backpack with $2000 worth of hiking gear that I will not be able to replace before I am supposed to leave on a trip. How could this happen?! This bag was full of all the material possessions in the world that matter to me.

Excellent 10.0

Cons: i wish Alaska would fly straight to Denver from Montana. I fly from Montana to Denver a lot and it ends up being a whole day of travel instead of a couple hour flight.

Excellent 9.5

Pros: The price of tickets. Plane was on time and crew were excellent. The plane was new and seats were comfy.

Cons: We did not know we needed to ask for our seats at the time of check in. A little confusing when we got to the gate. It turned out fine with our sitting in the seats for emergency. They were very comfortable.

Okay 5.6

Pros: The bus style seats really are more comfortable than other economy seats that can recline an inch or two.

Cons: I understand that the attendants must have been exhausted on the day after Christmas. The fee for bringing luggage seems too high, and not well displayed at the time of ticket purchase. This is misleading when comparing fares. Overall, Frontier offers a commuter experience, efficient and spare.

Mediocre 2.0

Pros: Nothing

Cons: It was a total shit-show. Only one person to check people in the counter. No kiosks were working on my way back. On the way there very few were working, I did it once, paid for my one bag, and it printed blank. There were no available workers to help me, so I switched to another kiosk and had to again, pay for my bag. On the way back we landed and had to wait 30 minutes to get to the gate. It was a horrible experience in all.

DEN
Okay 4.5

Pros: Cheap price.

Cons: Boarding process ineffecient. Pay for carry-on bag. Accept the seat you are assigned or pay to change. Should be renamed Nickel and Dime Airways.

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.
