Mediocre 2.6

Pros: The crew was friendly.

Cons: Both of our flights were delayed for two hours with no explanation. Other airlines didn't seem to be having the same problems. It is rediculous that they charge for bags and that they are the only airline with a 40 pound weight limit when all of the others are 50 pounds. They charge $10 just to print the boarding passes at the airport. All of this they claim saves you money on the fare, but with all of the nickel and diming that they do to you after you purchase the ticket, it is much more affordable to go with another airline. I will choose some one else to fly with next time.

Cons: Everything..I will not ever fly Frontier again. The cost to pick a seat, baggage, carry on's, snacks on the plane, and shitty customer service from flight attendants. I could have flown Delta non-stop AND have everything included. I will make sure tour spread the word. Awful customer service. Caused many people to miss connecting flights and made them pay for overnight hotel stays, missed work, etc. No sympathy or willingness to do right by the customer.

Mediocre 3.3

Pros: Not trying to be hurtful, but not much. The people sitting next to me were nice. The temperature was fine. Nice takeoff, flight, and landing. The seating in the terminal was comfortable.

Cons: The boarding was completely disorganized. The crew unprofessional. I overheard one crew member say to another "What is it with these Denver weirdos?". Then they complained about work and passengers the rest of the trip. I was in the front row and they must've assumed I couldn't hear them. I could. I know you're trying to reduce fares and making it an more a la cart experience, but $2.99 for a can of soda? Having to avoid the pile of ice that was dumped by the flight crew into the bathroom sink when i washed my hands wasn't very pleasant. The chairs are still incredibly uncomfortable, even in my "stretch" seating assignment ($35 poorly spent on my part). This trip made me rethink the cost benefit of taking Frontier. Flying United or American may be worth the extra money. And that's coming from someone on a tight budget. I used to enjoy flying Frontier and love taking a plane in general. I surely didn't this time.

My friend who we were going to see in Denver had flown spirit a few months before to come see me in Texas. And he had some unnecessary issues also with delays and unprofessional personnel. I won't be using them again. Use a different airline.

Cons: When I arrived two hours early to my flight, it was the first time I heard it had been cancelled. Apparently, due to weather. They said the only time they could get me out would be three days from then or they could refund me. No, they refused to pay for another ticket. So, I had to spend $435 on a ticket for later in the day when I had spent $130. Then, I look to Denver's weather and its perfect for the day. I call my mom, she's outside without a jacket! Where is the weather pray tell Frontier. This is the third and last time I ever use Frontier. Frontier is the worst airline I have ever used.

Cons: I have to say the crews going there and back could use a little more professionalism and customer service training. I don't wan't to blanket criticize all of them because I didn't come into contact with everyone of them as much as others, but I was put off by the flight attendants attitudes. They don't help as much as on other airlines and don't pass out food to everyone like on other airlines, so when I do order and pay for it, I expect a pleasant reaction, not to made feel like a burden.

Pros: I did not know what to expect flying first time on Spirit but was pleasantly surprised at the efficiency and kindness of the employees.

Cons: I was not pleased to find that the weight for a bag was 40 lbs and was charged $25 on top of the $40 bag fee for an overweight bag. This must have been in the fine print for I did not see it and packed my bag to be less than 50 lbs. The seats have no leg room and I found them to be restrictive for my 5'2" frame. They do not recline due to the space "saving" efforts of the airline. If you are looking for "cheap" remember to add on all the fees charged for bags, select seats, beverages before comparing to other airlines.

Flight was originally cheaper but by the time you pay all of there fees to get on the plane you're not saving at all. And once on the plane everything costs a fortune so now you've spent even more. They are never on time in my experiences and don't feel the need to give the paying customers updates. After several hours of delays you get the pleasure of being absolutely crammed in their crappy aircraft. NEVER AGAIN!

Good 6.5

Cons: The flight was delayed twice and ended up arriving hours after schedule. I get sometimes this happens. I was frustrated bc we were boarded and seated, ready to taxi with no pilot! It took another 30 minutes to get one! I realize when flights are late there are ripple effects but this was excessive.

Okay 5.3

Pros: The plane was not cleaned prior to departure so the bathroom was disgusting. One of flight attendants cleaned it , probably not her job but appreciated. The staff was terrific with an exhausted group of passengers.

Cons: This flight was more than two hours late. The updates were not shared at the gate and we were strung along about the departure time. If a person didn't have the app, little to no info was available.

Pros: My flight TO Denver was fine. Nice new plane, crew was pleasant etc.

Cons: My flight FROM Denver TO Houston was a nightmare. The plane was disgusting and smelled like dirty diapers. Everything was sticky and gross. I had to throw out the clothes I was wearing on the plane afterwards. I cannot believe the inconsistency. Never again will I fly Spirit.

Cons: The seats are cramped and on the way back, they canceled all flights back to Houston, causing us to pay an extra $600 in order to get home to work on Monday.

Excellent 8.5

Pros: I did not know what to expect flying first time on Spirit but was pleasantly surprised at the efficiency and kindness of the employees.

Cons: I was not pleased to find that the weight for a bag was 40 lbs and was charged $25 on top of the $40 bag fee for an overweight bag. This must have been in the fine print for I did not see it and packed my bag to be less than 50 lbs. The seats have no leg room and I found them to be restrictive for my 5'2" frame. They do not recline due to the space "saving" efforts of the airline. If you are looking for "cheap" remember to add on all the fees charged for bags, select seats, beverages before comparing to other airlines.

Pros: Nothing

Cons: I wasnt allowed on my plane when it wasnt leaving for 43 minutes after i had arrived there. I would have been there the RECOMMENDED hour and a half early if i hadnt run into heavy traffic. Unfortunately, I only had 43 minutes before the plane left denver and the crew told me that i was late and wouldnt even give me the opportunity to try and get to the aircraft before it left. Then they told me that i could pay almost double what i had origionally spent on the flight to wait 4 hours for the next one with a 6 hour layover for thr connecting flight. I had then asked if it was possible to be reimbursed, the guy at the counter started laughing and said no it was my fault i was late. I have never been treated with such disrespect before in my life. I just dont understand, because no where does it say that if you're not there 50 minutes prior to the flight that you forfeit your flight. 50 minutes, i was there 43 minutes prior. Now i wont be able to visit my family for another year because i used my vacation time for that aweful experience with spirit ovwr 7 minutes. Then when i called kayak to explain to them what happened, they told me there was nothing they could do over and over again. Absolutely no help from either party.

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.
