Mediocre 2.0

Pros: Nothing. I was treated so poorly I walked away from their customer service and bought a ticket on another airline.

Cons: I was 5 minutes late over their 45 minute required check in window. So they cancelled my ticket. For $100 they offered to reschedule me. And for another $50 they would check my bag. On a different airline I paid another $100 and got a complete round trip ticket, about 10 minutes later.

Pros: The option to have the first row with more comfort. The crew was nice.

Cons: I'm upset that my bag came back broken. I've checked my bag several times with American and this never happened. Needless to say; this is my first and last time. It only takes one bad experience to lose a customer.

One poor soul is running around frantically trying to address all the check-in issues Pre-TSA doesn't start before our 5:15AM flight so after walking all the way down to the Pre-TSA checkpoint, we encountered a sign redirecting us back the normal tsa checkpoint which was overflowing with late check-in customers upset with the long kiosk check in delays

Cons: How they canceled one of my flights just as I landed at my layover for that flight when I look back at Boston they had a direct flight ready for my destination. Very poor management I was stuck in Chicago with no money or food for hours then after they start boarding for my new flight they tell me that I may not be able to get on even with ticket in hand. It was a joke and very stressful

Mediocre 2.0

Cons: United is a horrible excuse for a company. 3 mechanical delays ultmately causing us to miss a wedding which was the reason for our trip. 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.

Not only dod we loose our tickets but also the money for the fees we had already payed for. I had an uderstandong that the gates closed 10 min prior not 45. We had to fly becuase we had an emergency and this inconvinience just made our experince horrible. Defenetly dissapointed.

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!!

Okay 5.0

Pros: Well I liked that I got there and that the price for the flights in total was $190 (kayak SLAYED at getting me the right price). But I was expecting a continuation of excellent service that I got in white planes New York to continue, and be elevated, because they didn't have the same troubles that my previous airport did.

Cons: There were just too many failed opportunities. The biggest was the gate agent who was "just filling in for another guy who's suppose to be here." I'm like well if someone is in line, even if they hop in line, you need to give them the best service because you're the face of the company.

I didn't pay to request a certain seat, so I was in the middle seat of the last isle for each flight. The "free" entertainment was ads to purchase entertainment.

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.

I can't believe they haven't invested in this type of tracking system....its 2017!!! Very bad customer service. No communication or mis communication on status of lost bag. Really they have no idea where it is. Promises to deliver lost bag at certain times and never do. Took time out of my day to stay home and wait for bag between 12pm - 6pm as they asked. Never showed up. Never called to say they wouldn't be showing up. They did this to me 3 times! It's 1 week later and I still don't have my bag. My ski trip was completely ruined. I've flown domestically, internationally, and I have never felt so uncared for as a customer. Tales of this terrible airline were told to me before I chose it. I can't stress this to any future potential customer. Choose another airline. Not worth it no matter how low the price is. Hidden baggage fees and terrible customer service will get you in the end!

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 4.5

Cons: My flight was delayed by two hours due to weather, which is not under Spirit's control, but there was little to no communication regarding the delay. The online flight status wasn't updated either throughout the duration of the trip and so my sister, who came to pick me up, was stuck wondering what was going on at the airport for two hours.

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.

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.
