Poor 0.0

Cons: The airline lied to the passengers. My flight started from Guayaquil with a delay. Once we arrived to FLL they made us believe that the ground personnel will help us. Nothing more far than the truth. I lost my connection and the best solution was to leave me almost 36 hours until the next fligjt the airline wanted to rebook me. I ended up paying another ticket in another airline. Spirit will not recognize me anything, even if the delay was 100% their fault.

Pros: We were at the frontier check in desk at 5.40 pm to discuss options. There was nobody at the desk so we waited for 10 minutes.....nobody showed up. So we decided to call frontier airlines which. Took about more that 20 minutes and leaving leaving us no time to catch the flight. We told them that we've been waiting here andretimg to get a hold of a live person to talk to and now we cannot catch our flight since only 10 minutes are left now for flight to depart. They said that now I have to buy another ticket and all the flights are booked until Tuesday......I said what???? So....not our fault we could not catch the flight( which bra still have time to catch), but there is no waiting list or anything until 3 days? And that also I have to spend 3 times more to buy that ticket?? All they said is pretty much.....is "fuck yuu" Leaving is no other option but to book a last minute another airline flight costing us $850 extra. We were not considered as humans.....no regard, no help and no respect. WORST AIRLINE!! that is why I am not going to take my today's flight and will never book frontier again and would recommend everyone to never book frontier.....

Pros: The crew was great. The pilot lightened the mood with humor and the announcements were useful ( weather, time zone changes, ETA etc... ). The plane was clean and the price was low.

Cons: You have to pay forty dollars for a carry on and for any beverage or snack on the flight. There was confusion about the seats as we boarded, which we did by zones, but still had aisle traffic which defeated the purpose. My connection was moved to another gate and they failed to announce it ( yes it was on the screen, but I don't travel that often and was lucky to notice it just as we were boarding... luckily just a few minutes walk away ). The plane offers no entertainment at all ( which is fine for me, but worth knowing... bring a dvd player or something for long trips ).

Cons: I am in the military and was traveling with a ceremonial sword for a wedding because I was in the wedding party. The sword was placed in normal checked baggage, but never arrived in my final destination in Seattle. At the airport, there was no one at the front desk. After calling later, I found that the sword had made it, but I had to pick it up myself or be charged for delivery. The hours were awful at only two parts of the day in two hour windows. Preparations for the wedding made it difficult for me to make the times and I was unable to have it for the wedding. When leaving, I was able to get the sword back and I re-checked it to Washington D.C. this time in oversize baggage. Again in Washington my swords was not there and there was no one at the front desk to ask for help. Now I'm back in the same place waiting for frontier to get back to me to locate my sword. Needless to say this will be my last time using frontier airlines.

Mediocre 2.0

Pros: Literally nothing.

Cons: I charged the airfare, thinking that would be all, like other airlines. Then I found out they charge for luggage. THEN I found out they charge me for a seat... on the flight I already paid for. Boarding was disorganized, seats were thin padding on plastic, quite uncomfortable. I also had to clean crumbs and trash off my seat before settling in. They charge you 2.99 each for water and airline peanuts; i didn't partake. they only gave me one boarding pass and when I boarded the plane, they said that is was the flight to Denver and then they were continuing on to Columbus. I assumed this meant I stayed on the plane when we landed in Denver, but no, they informed me the plane was then going to Cedar Rapids. I had no second boarding pass or gate number, so I asked the attendant. She took forever to help me, looking up my info for a minute and then talking to the other attendants and passing out papers to the boarding crew before acknowledging me again. Twenty minutes later, I had my gate, which I barely made to board in time for flight takeoff. Overall, the process was stressful, uncomfortable, and more expensive than if I had purchased a flight from Delta, Southwest, or Alaska. (All airlines I have flown and been happy with. Delta had a missed layover once and completely put me up for the night and was very helpful through the whole affair.) All said and done, I will not be flying Frontier again.

Crew was fine but I won't choose Frontier again because of the additional charges for things that should be included in a competitive ticket price.

Pros: I love the new snack choices! Way to go Delta for offering Kind bars now!! This is awesome.

Cons: Tiny old plane, props blocked my window view, no entertainment system.

Okay 5.5

Cons: I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights.

Mediocre 2.3

Cons: Dirty plane. Tight quarters. Mismanaged time. Unorganized. Not worth the 20 dollar discount in comparison to other airlines that have more comfort and don't charge an outlandish amount for a carry on. It was my first time flying Frontier, and needless to say I was incredibly disappointed. Loaded onto the plane until we were supposed to take off, then deplaned for what they said would be an hour of required maintenance (which I don't know why they didn't take care of ahead of time), turned into 3 plus hours. And they can't even offer a complimentary beverage? Unimpressed, all around.

Mediocre 2.6

Pros: This was not a deal at all! I should have just flown straight into Grand Junction on Alaska. You can't drop off bags until 2 hrs before flight which is no good @ a busier airport like SEA. There were no USB outlets or wifi available. The seats were uncomfortable & the extra space they charged for was bolony. Plus I had to pay $40 to bring a bag or if you needed to store a carry on in the over head you paid. Not one type of drink or snack was offered. Then I also rented a car where I got the insurance & then to find out that it's a third party insurance & doesn't count. Plus I am fighting Hertz on extra time charged even through I told the woman who checked me on that I wouldn't be back until 4. If I knew I had to be back earlier I would have been. The flight & rental car experience was terrible. I don't think your intentions are at all to help save people money.

Cons: Seeing my family.

Excellent 10.0

Pros: Despite all the bashing that Frontier/Spirit airlines take, for reasons I am yet to figure out, my experience with Frontier has been awesome. Considering I fly between Seattle and Denver every week, this flight has always been on-time if not BEFORE-time and has never failed to meet expectations unlike another airline on this route at about the same that messed up THREE times in past 6 months. Interestingly, those were the only THREE times I chose a non-FRONTIER and they were over-booked, delayed and system-down. So, the joke is on them, and Frontier just proved to me that tables have turned in their favor. Kudos Frontier and your awesome staff on the Seattle to Denver flight that takes off at 6.25pm from Seattle every Friday.

Excellent 10.0

Pros: I was made to feel comfortable right from Bangalore by the checkin people, because I indicated to them that I had a fear of missing my connecting flight from Seattle to Denver. My connection to Denver went smoothly,however the flight attendants on Air Alaska need to be more courteous and friendly.

Cons: Did not like the flight attendants but the pilot made up for the humour that was lacking. Never seen a pilot interacting the way this one did.

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.
