Pros: Although the plane was delayed, the staff did want they could to get us to our destination as quick as they could.

Excellent 8.0

Pros: Fine for a domestic flight. Normally, American Airlines offer a small snack to go with the drinks. But on this particular flight, they went the United way and offered nothing but drinks. Crew was pleasant enough during the flight, although they didn't greet half of the passengers entering or exiting the plane.

Cons: Flight was a little late taking off and therefore getting to Denver. But there was no announcement about it. There was one announcement from the captain, but it was so soft that I couldn't hear anything. Upon landing and arriving at the gate, we stood there for a while with no lights on and seatbelt sign on, but no explanation of what was going on. There was no welcome to Denver message either. Maybe their announcement system was down.

Cons: It's been 45+ minutes after landing that we have been stuck on the runway unable to dock the plane due to some delays. How Terrible is it that the pilot gets on the radio to say he has no updates or much information to give! People are antsy, children crying and this delays all passengers with other accommodations.

The manager who came to save us was rude and did absolutely nothing about it. I had to find another flight on my own and pay extra and reschedule my car rental and hotel reservations.

Mediocre 2.0

Pros: Nothing was positive while using Frontier Airlines

Cons: Everything was pretty unpleasant: 1.) hidden baggage fees ($45 round trip would be one thing for a CHECKED BAG, but $90 collectively for the round trip is FRAUDULENT) Especially when most airlines don't charge for carry on bags or it's at least calculated in the final cost. At first when I booked this trip with FRONTIER $180 for my tickets looked like a decent deal, UNTIL I WAS TOLD AT THE COUNTER THAT I HAVE TO PAY $45 each way for a FRIGGIN CARRY ON BAG!! turning my reasonable and anticipated $180 trip turned into almost a $300 (NEARLY doubled my cost!) had I known I could have at least packed more into a checked bag for that price. 2.) my flight was delayed 4 hours on my outgoing flight, cutting into my personal time off and no compensation or even a kind gesture like a free McDonald's sandwich when you land...you guys really have poor quality and seem like you don't really care about the paying customer 3.) staff seemed clueless and didn't know how to answer customers questions as to why our flight was delayed!! 4.) mechanical issues with plane were the cause, or at least that's what the copilot or captain Just HAD TO MENTION TO US RIGHT BEFORE TAKEOFF, causing everyone to stir and raise eyebrows. 5.) to top off him mentioning the mechanical issues they were having with the plane the flight was rough..I've never been more tense or anxious on any of the other 30+ flights I've taken in my life. Pilot didn't seem to know how to handle turbulence.

Pros: Not much.

Cons: Frontier Airlines Lost My snowboard bag. No electronic system to track bags means you must rely on their human communication, and this is terrible. I can't believe they haven't invested in this type of tracking system....its 2017!!! Very bad customer service. No communication or mis communication on status of lost bag. Really they have no idea where it is. Promises to deliver lost bag at certain times and never do. Took time out of my day to stay home and wait for bag between 12pm - 6pm as they asked. Never showed up. Never called to say they wouldn't be showing up. They did this to me 3 times! It's 1 week later and I still don't have my bag. My ski trip was completely ruined. I've flown domestically, internationally, and I have never felt so uncared for as a customer. Tales of this terrible airline were told to me before I chose it. I can't stress this to any future potential customer. Choose another airline. Not worth it no matter how low the price is. Hidden baggage fees and terrible customer service will get you in the end!

Mediocre 2.0

Pros: O'hare airport.

Cons: I was unable to print a boarding pass at one of the many kiosks - it informed me I needed to speak with a Frontier agent. The line for the agents was about 2 hours long, too long to wait to make the flight. After being told by a frontier employee that I'd just want to get in to the line to rebook on a later flight (9 hours later) I proceeded to speak with a momentarily vacant agent who, helpfully, printed and handed me my boarding pass. I arrived at the gate to a closed door and ended up needing to rebook anyway. I decided to just not go on the trip.... wasn't worth having to deal with Frontier 2 times in one day.

Mediocre 2.0

Pros: We arrived

Cons: Two hour delay with no reason why which is a really big deal when you arrive at your destination at 1 in the morning and you need to be up to baptize a child at 8 the next morning.

Mediocre 3.3

Pros: We didn't die. Plane was early, which was nice.

Cons: Plane was horrible uncomfortable. Boarding area was crowded to the point of insanity. Seats are so thin I can feel every adjustment of the children behind me. Not even water offered. Spirit upcharges for everything, so it ends up being MORE expensive than competitors. My absolute last time flying this airline.

Good 7.0

Pros: Staff were nice enough.

Cons: Plane was over an hour late. Seats are too small and cramped and the man next to me had body odor. I know this is to be expected of a budget airline but it seems that airlines are going to crazy extremes with the size of seating.

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.
