Pros: I never made it on the flight. It was delayed serval hours and eventually cancelled. I few American to Chicago.

Cons: This was one of the worst travel experience I have ever had. My flight to Denver was delayed over an hour causing me to miss my connection and I had a 3.5 hour layover. My flight leaving San Diego was delayed serval hours. Eventually was cancelled. I should have been home by 6pm didn't get home till 11pm. Both flights delayed due to issues with the planes.

Okay 5.5

Pros: The flight was on time and all employees I spoke to were kind.

Cons: Buying the cheapest flight only to find I can't check in online, can't carry on a bag and cannot select or change my seat is hugely disappointing. I know this is largely standard across airlines now, but it is despicable how uncomfortable and painful the process of flying has become when one isn't able to shell out a billion dollars for first class. You all need to get your priorities straight and think about your customers again.

Cons: No one at counter for checking, had to wait 45 minutes for a representative to check in. Seats are the most uncomfortable of any airline i have ever used. Will charge you $3 for a cup of soda on a 4 hour flight. No entertainment, no wifi. They charge you if you want to pick a seat next to your spouse. $40 for a carry-on Red eye flight, no pillows, no blankets, airpline was freezing cold. .

Pros: This was our first time using Frontier and we were skeptical because of the low fares. At each step along the way we were glancing at each other and waiting for the other shoe to drop, but were very pleasantly surprised by the end of the trip to have found nothing wrong or hidden. As a person who has flown regularly for over 40 years on both budget and full service carriers, and had always enjoyed it up until the late 90’s, at which time I really began to dread going through the entire process; this was a really pleasant surprise. On our way home in the car after our return, both my wife and I agreed that this was the first time in years that we didn’t have any complains about the experience and that we actually had mildly enjoyed it. Maybe that was just a lack of pain. At least on this first time using Frontier we got more than we expected. I think if you take the time to understand the business model the first time you book and you follow the booking process; the seat and baggage selection choices and the check-in procedures, you will get a good bang for your buck. We did upgrade some selections but even with that, we were still way under the next carriers fare price point. Maybe if we had not taken the opportunity to upgrade during the online booking process it might have been a different experience. This flight was two round trip tickets from Cincinnati to San Diego. The first part was a non-stop and the return was a one-stop in Denver. All three legs were on an Airbus 320’s. On all three legs we had isle seats in the first 6 rows (2C/ 2D, 3C/ 3D and 6C/ 6D). We don’t care about, nor expect frills; we only want to get there and back comfortably with good value fares; and that’s what we got.

Pros: Gate check of carry-on luggage was nice. The connecting flight from DFW to FLL was on time and the boarding process was very smoothly executed by the gate agent. Well done!!

Cons: The flight out of RNO early in the morning was chaotic. One of the kiosks was down and the line to self-check was long and moved very slowly because there was only one agent behind the self-check baggage drop. She did well keeping up but there was a long line of unhappy customers due to the long wait. No snack was offered but I did get a glass of water. Not enough overhead storage for the carry-on bags because passengers get the luggage check tag but brought the carry-on onboard anyway.

Cons: Flight was cancelled due to mechanical issues at 1030pm after waiting for 4 hrs. We were all sent to the front desk, got there, and no one came to help us for 30 min. The guy from the gate actually had to come up, I felt so bad for him. He gave - few people at the front of the line cards to call to rebook, but the phone number didn't work so I just called the help line. But most people didn't know and weren't told they could do that. Instead the guy helping us had us form two lines, one for rebooking and one for refund that didn't move for the next half hr. They didn't tell anyone in the line they could call someone so they just waited. The worst is that they told everyone Spirit would not be offering accommodations. It really seemed like a "we aren't going to deliver the product we promised and good luck figuring out what you'll do now." By the end of it, I was just happy to get a flight for the next night. I'm not sure what happened with everyone else once that flight was filled because there were no others. Between the astronomical bag prices and the worst customer service I've ever seen, I won't be flying with Spirit ever again.

Excellent 10.0

Pros: This was our first time using Frontier and we were skeptical because of the low fares. At each step along the way we were glancing at each other and waiting for the other shoe to drop, but were very pleasantly surprised by the end of the trip to have found nothing wrong or hidden. As a person who has flown regularly for over 40 years on both budget and full service carriers, and had always enjoyed it up until the late 90’s, at which time I really began to dread going through the entire process; this was a really pleasant surprise. On our way home in the car after our return, both my wife and I agreed that this was the first time in years that we didn’t have any complains about the experience and that we actually had mildly enjoyed it. Maybe that was just a lack of pain. At least on this first time using Frontier we got more than we expected. I think if you take the time to understand the business model the first time you book and you follow the booking process; the seat and baggage selection choices and the check-in procedures, you will get a good bang for your buck. We did upgrade some selections but even with that, we were still way under the next carriers fare price point. Maybe if we had not taken the opportunity to upgrade during the online booking process it might have been a different experience. This flight was two round trip tickets from Cincinnati to San Diego. The first part was a non-stop and the return was a one-stop in Denver. All three legs were on an Airbus 320’s. On all three legs we had isle seats in the first 6 rows (2C/ 2D, 3C/ 3D and 6C/ 6D). We don’t care about, nor expect frills; we only want to get there and back comfortably with good value fares; and that’s what we got.

Cons: Nothing

Cons: The flight was delayed for over an hour and then cancelled. We had to wait AN ADDITIONAL three hours to get on another flight. My wife was able to make the flight change on her cell phone because of the slow response of the agents. Out of five flights on our trip, three were delayed or cancelled for a total of nine plus hours!

Mediocre 3.0

Pros: I liked the leg room

Cons: Horrible customer service.... maybe spirit should raise everyone salary because the entire crew looked out of it .... absent minded. That's not the spirit. No pun intended! Flight cancelled. Because a flight attendant didn't feel well. Replacement flight both delay by more than an hour each. I was treated like a thug until I showed my military ID ...that's sad

Pros: Both flights, Denver - San Diego and San Diego - Denver left and arrived ON TIME! Very happy

Cons: For a 98$ flight including insurance I guess the only thing I can complain about is the 50$ checked bag fee. But still was a decent deal.

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,
