Mediocre 3.0

Pros: Nothing

Cons: We were delayed and received no update prior to arriving at the airport. Our gate was changed suddenly just before boarding time and then waited an additional 30 minutes to board with no information. We then sat on the plane for about 30 minutes, doors locked not moving, again no information. I did finally receive an email update that our flight was delayed after we'd boarded the plane. We are now landed in Denver and just sitting on the plane not moving pushing 40 minutes, what a suprise-with no information.

Pros: Fast boarding and that's the only good quality. No refreshments or snacks offered without a price tag included. Seats don't recline. Uncomfortable hard seats without any head rests for Support. Small tray tables that won't hold a laptop or drink.

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. Seems like there's no communication or organization from Frontier at all!!'

Pros: Boarding process was efficient and crew was nice. Flight was slightly delayed, but the pilot made the attempt to make up time in the air. I don't tend to recline my seat, as I don't like to cram other's space more than it already it. It was nice that no one could recline.

Cons: Can they cram these seats any closer? Wow, I am certainly not tall, and trying to get my bag from under the seat was almost impossible. Super pricey bag fair for less weight when compared to other carriers. Be aware when flying this airline. They seem to be fair weather fliers. Any sort of weather condition, like snow, may cancel the flight.

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. By far the worst experience I've had at the airport please don't be cheap and think you are saving with spirit, they are a headache and worst service ever!!

Pros: The crew was amazing - agreeing to work extra because it was Christmas eve and they wanted us all to get to our destinations for Christmas. They were very gracious and helpful.

Cons: We were over an hour late to leave. I understand the reason for the delay because of weather. What I was disappointed in is that the delay was not announced until our actual scheduled time to leave. It meant people coming to pick me up didn't get the change information in a timely manner.

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.

A 5 hour delay out and an overnight delay in the way home. We slept on the floor in the airport- one thing for us but disgusting to see United allowed this for elderly and families with toddlers and babies. The third mechanical delay occurred after we were finally bored and on the runway and they wouldn't let us deplane. Never have I been so terrified to fly.

Good 7.0

Pros: Boarding was fairly quick and on time. Transfer in Phoenix was no problem. Luggage arrived OK.

Cons: Seating is too small and too close to next rows. Unhappy with having to pay for seat assignments and checked bag while watching gate agents refuse to enforce overhead bag size limits.

Mediocre 3.6

Cons: Not much. Brand new 737-800 that was the most cramped uncomfortable cabin/seats I've ever been in next to a commuter flight. Middle seat in the last row no recline didn't help. And my knees were up against the seat in front of me all the way. Was battling back cramps and spasms. Felt like a sardine. And we got no beverage service

Mediocre 3.0

Cons: This flight was canceled because my initial flight was canceled by united and then I could not take the rebooked flight so I could not keep the seats together with the travellers I was with and then was placed in the back of the plane. When my flight was canceled initially no one informed me that my return ticket would be canceled which I specifically asked about. I hope never to fly united again. The day to day staff at ohare and on flight were good and courteous.

Mediocre 2.0

Pros: Delayed. Bagage mis-rerouted.

Cons: Be honest when bags are not routed correctly after assuring passenger twice that bags will be at the same airport they were re-routed too. Do not ask passengers for a bag delivery fee when the mistake was United's. Keep passengers informed of delayed flight and keep inconvenience to a minimum.

Cons: I want to clarify that I boough tiquests with Lufthansa not with United... and I had to travel United most of the time to Africa and Bach to the USA... united socks terrible ... bad food and old plain to cross the Atlantic... besides the service and the bad actitude of the employees... when I travel international I want only Lufthansa. So, kayak you tricked me ....horribly!

Okay 5.6

Pros: Flights were smooth and crew was great.

Cons: Maybe it was listed in the booking details but everything has been stripped down and everything has an outrageous fee. $45 at check in to check a bag OR carry on a bag , $3 for a soda in the plane, no free snack, stripped tray table, seats don’t recline, poor armrests. I won’t fly Frontier again if given the choice.

Okay 4.0

Pros: The price of the flight

Mediocre 2.6

Pros: What I liked? That the flight ended and I could get off the plane.

Cons: They charged to pick seats. They charged to carry on a bag. They charged for any drinks. The seats had NO padding. The seats didn't recline. The gate at O'Hare was dark and dirty. The travelers in my flight would have scared the residents of Mos Eisley.

Excellent 8.0

Okay 5.0

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

Cons: Delayed flight, which was fine but didn't update passengers as to why until we boarded plane. I didn't appreciate that as a customer. Questionable if I'll be a return customer in the future.

Mediocre 2.0

Cons: Nothing about this flight was relaxing or welcoming! The staff was extremely rude. To check a bag in its way over priced. I asked for a cup of water in which I was told it would be three dollars for a bottle of water . WATER! The seats on the plane were extrmemly uncomfortable. Overall I would never recommend nor fly spirit again.

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.
