Mediocre 2.6

Pros: Started with the nickel and diming during check in. The app wouldn't take my card so I had get on the website. Apparently buying the ticket doesn't give you a seat, you have to pay extra for that. Taking more than a laptop bag or purse, that's extra. Right there, your low fare is shot to h#ll. Definitely check the hidden costs before booking. Then came a 5 hour delay of the flight, apparently the plane had mechanical issues at it's previous stop. Frontier provided $10 meal vouchers, which doesn't go far in an airport. Seats don't recline at all and you feel like you're in a cattle car. The seat back tray is about 6" and doesn't hold much. The combination of turbulence and a pilot yanking the plane around during landing brought out the air sick bags by several passengers around me. Then on the ground, he was racing around and taking turns like an Indy500 race car. I seriously thought he was going to do a handbrake turn into the parking spot. Frontier provided vouchers worth $100 per ticket for the flight, but only good for another Frontier flight. I don't think so...

Cons: Several hidden costs. Uncomfortable seats Rough landing

Mediocre 2.0

Pros: Getting off the plane.

Cons: Missed my flight because lack of people to check people in. So slow. Waited 25 minutes. Figured I missed my flight since the board said on time. It was 2:25. Asked if I could get on 7:30 flight. Took computer 10 minutes for her to see and book. As I left, she said the 2:30 was still boarding. I said, oh, do you think I could still make it? She said the plane was still loading and running a bit late, but impossible to get on because I was booked on the 7:30 flight. I will probably not fly Frontier again. 4 hours later and $50 dollars in the hole for food and drink sitting here dreading my middle seat and no room to move for 2 hours. Then, have to pay for a Lyft to get to my car because my cousin was my ride back to her house. I sure do miss the old Frontier.

Pros: new jet. enough leg room (i'm male, 5-10). Overhead bins are normal size (can hold typical carry on), not the microscopic ones. Everything was on time.

Cons: STL ticket counter was only staffed 2 hours before the flight -- which makes sense if they didn't have more flights, but the signs weren't big and complete enough for passengers to realize what was going on and how we would check our luggage. So we were standing around a bit confused. Once Frontier people showed up, it was fine. Also, coming back to STL, I had a 2 hr shuttle bus ride that was leaving 30 minutes after arrival, and although the plane arrived on time, the luggage didn't reach me until 37 minutes after, so I had to get a hotel room for the night. I don't know how luggage handling works, so maybe not Frontier's fault at all. 30 minutes isn't much time, but it was a direct flight, so I thought it would work.

Pros: Made up time lost to bad weather. Several announcements from pilot-I always like that. Makes me feel more personally cared for. "My friend the pilot is taking me there". That might explain how it makes me feel. Wish they did it more. Don't usually complain but below you will see I did.

Cons: Your headrest are especially cheap, plastic like, with little padding. Being in back row(no recline) would have been manageable if I could have leaned head to side to rest on something that extended out. Left too much light on (all down center) for an overnight flight. Served heavy dinner at 2am. Woke everyone up. Later light breakfast would have been more appropriate. Bathrooms reeked and waste bin overflow. Stewardess in back chatting. Don't they ever check?.

Good 6.0

Pros: This added almost $100 to the face. I'll try to avoid Frontier in the future. Gotcha capitalism!

Cons: Cheap fare until it changed with the bag fee

DEN
Mediocre 3.6

Cons: How is it acceptable to place someone who is highly allergic to dogs right next to a lady with a service dog on the flight? I spent 25 bucks to upgrade my seat to avoid the nuisances of an everyday flight. I didn't think I'd be stuck next to an animal. How is it acceptable to not disclose that I'd be stuck next to a service dog? I was miserable the entire 2.5 hour flight back to denverz I am extremely irritated.

Good 6.0

Cons: The price of drinks and food. They should be comparable to a grocery store if you're going to charge for every little convenience.

DEN
Okay 4.0

Okay 5.0

Pros: Unlike some airline pilots(Spirit) these guys actually communicate with the passengers.

Cons: Have working charging ports, improve space for comfort.

PDX
SFO
Good 7.2

Pros: Exceptional price on a direct PDX-SFO flight at $66 roundtrip. USB outlets at all seats I could see. Looked to have a good selection of in-flight entertainment available to stream to personal devices (phones, tablets, etc) Staff were low-key.

Cons: Basic fare: no reserved seats, only personal item. Like United (but not Alaska/Delta) require desk check-in at airport!! No online check-in/mobile boarding pass, and *limited agent hours* Lame. Buy-up reserved seat (fee) Stupid policy for passengers, extra work for staff.

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.
