Mediocre 2.0

Pros: I didn't get a chance to book

Cons: So I checked my suitcase and the terminal employee who checked me in tells me I have to hurry to flight (30 mins to board). I get there before boarding and the counter kid says he sold seat to someone else. Why didn't baggage taking employee alert me to this before? That my seat was sold? Really?

Mediocre 2.0

Cons: Flight was cancelled with no reason given, it took almost an hour to call and get my return trip cancelled because the website would not allow me to change my flight. Representative tried to reschedule me for a 12 hour trip when the original flight was 2.5 hours before finally cancelling my trip all together. Spirit ended up costing me $150 more than had I booked with another airline at the beginning because I was left having to purchase a ticket day of on a competitor.

DEN

Mediocre 3.0

Pros: Fast boarding, but then we sat with the door open for 20 minutes. Flight was fine. I would only ever consider flying again if there was a phenomenal price break from the next cheapest airline.

Cons: Gate change with no announcement or change on departures board. Late takeoff. Tiny cramped seats, and miniature tray tables. Trash in front of my seat at boarding. The majority of passengers seemed to be inexperienced flyers, maybe gravitating towards the cheap fare? VERY annoying, needy, chatty, panickey at take off and landing. Not a pleasant environment.

DEN
IAH
Mediocre 2.0

Cons: Extra hidden charges. The kiosk wasn't finding my ticket from the flight number given so I went to the counter and spirit wanted to charge me to find the ticket I'd already bought from them! I was shocked. Also on line I was led to believe a carry on was included, but again I was charged. Seating was terribly cramped. I will do my best to never fly Spirit in the future.

Pros: Flight attendants were awesome. Especially the elder Caucasian lady. She seemed genuinely happy and was the highlight of the trip. On time. No delays. Fast boarding process. Seats didn't recline but we're fine for a short trip.

Cons: The landing was unsettling. Maybe the wind was strong but I genuinely was concerned. I'm not normally a nervous flier but this landing did worry me. But we did land safely. Also annoyed at fee structure. This is my first and last time to fly frontier simply because of the fee structure, even if it means paying more elsewhere.

Pros: Stewardesses were very nice and pleasant. We left timely and arrived on time.

Cons: My seat got randomly assigned and I was put on the back row window seat with no window. I wish I could have selected my seat from a list of free spots (w/o extra charge). I don’t like that you are charged for everything: seat change, water, and any snack. I would expect at least water as passengers get dehydrated from flying. Seats are uncomfortable, not much space from seat in front, and there is no recline. Feels crammed. Lacks hospitality majorly as I am charged for every little thing. I hope they don’t start charging for oxygen intake. I was not informed of entertainment options, but I’m sure they were not inexpensive. I will not be flying with Spirit Airlines again. There are other airline options that are less expensive (after you add all the additional fees up) and much more comfortable and hospitable.

Cons: The staff at the Frontier check in desk was extremely rude. (Which I can imagine is because they spend their day getting fussed at because of how awful Frontier is). I was charged over $100 per way for my family to bring very small carry on items onto the plane. I have NEVER heard of being charged for very small backpack sized carry ons. When I questioned the staff member, she looked at me and literally did not respond. She stared at me like I was speaking another language. I waited over an hour and a half for our checked bags to come to the baggage claim area. Everyone was looking for Frontier staff to help us as our bags didn't seem to be coming. The two staff members we found were HORRIBLE and extremely rude. They stood there leaning against the wall staring at us and telling us they couldn't help us - It isn't their department? The seats are uncomfortable- they do not recline at all. They charge for EVERYTHING on the plane- including drinks (non-alcoholic). Overall, the staff was rude, the charges were outrageous, and the flight was uncomfortable. I have never had such a horrible experience and will NEVER fly Frontier again. .

Pros: The flight was uneventful.

Cons: 2 hour and 45 minute delay. Nothing offered in compensation, paying for every bag, and the seats are uncomfortable.

Okay 5.6

Cons: It may be customary now, but we arrived with all our luggage as carry-on bags. We learned that they now charge more for carry on luggage than they do for checked bags. So we ended up checking two carry-on bags that we could have easily consolidated into one larger bag if we had known ahead of time. 2nd and worst of all - when we were checking in they told us our seats were not yet assigned (even though I picked seats out when I purchased the tickets). They showed a seating chart, but the only seats together required a premium payment of an extra $30 per seat! We complained and they told us to let the computer assign seats for us. That worked and the computer ended up assigning us two premium seats together. By the way - I did see what was "premium" about these seats. They reminded me of spirit airlines. Overall it seems like frontier is now trying to find ways to charge customers for things that were previously included and it is somewhat intentionally deceptive. I appreciated the low cost of the ticket, but I was left with a bad feeling overall. Spirit airlines is an inexpensive no frills airline as well but at least they are upfront and direct. I will fly with them next time if I have to, or go back to United.

Pros: Entertainment was offered on the flight

Cons: Flight was 90 minutes late Crew took an additional 40 minutes to get passengers with disabilities off the plane. There's no reason it should have taken that long. After I paid for entertainment, the crew announced it would be free for everyone since we were so late. Crew member was super-grouchy. Seats couldn't be smaller if they tried to sit you on a postage stamp. I'm a tiny person, but this is ridiculous!

Good 7.3

Pros: Staff was all friendly and exhibited positive and helpful attitudes. I also think the price and route was an excellent deal for this flight. It was actually such a good deal, it’s the main reason I even went.

Cons: I think the baggage restrictions thing is really slimey and a shameful scam. I actually wouldn’t have minded paying around $50 more for my ticket and hand the bag included than be misled into thinking I could take luggage and finding out after it’s too late that I have to pay for my luggage. I think it’s a really sleazy business tactic (akin to resort fees). Fortunately for me however, I don’t travel with luggage so it doesn’t directly affect me. Still think it’s. Shitty way to do business though.

Pros: Flight crew was great, seats were great.

Cons: Checking in was a nightmare with rude and nonchalant United agents who seemed oblivious to the late/canceled flights pandemonium with passengers scrambling to get questions answered about the rebooking possibilities being offered. I got a text message at 4:30AM about delay and rebooking opp.

Cons: So I checked my suitcase and the terminal employee who checked me in tells me I have to hurry to flight (30 mins to board). I get there before boarding and the counter kid says he sold seat to someone else. Why didn't baggage taking employee alert me to this before? That my seat was sold? Really?

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.
