Pilots that did show up were pleasant and made the best of the situation.

No scheduled pilots for this flight. Pilots that did arrive had their schedule rearranged---they showed up to work thinking they were flying to Seattle. They were asked to step in to fly to Denver instead---20 minutes after our scheduled takeoff time; not horribly late, but seemingly disorganized, which leads to all kinds of thoughts about AA overall competence.

The corner cutting is starting to cross a line. I had so little room that my knees touched the seat in front of me and I couldn't grab my bag below the next seat without disturbing the people next to me. 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. Obviously they now make you pay a about 20% of your ticket cost to bring a rollaway now.

Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines.

I had to re-purchase the same ticket I already bought because I missed another flight on the same itinerary, they cancelled this leg of the trip for me. Spirit will rush the planes out so they have a better on time percentage and regularly leave many passengers behind. Then you have to buy tickets again because it’s in their terms (and I believe other airlines terms too) that they cancel remaining legs if one is missed, and there’s nothing you can do about it

There's no padding and baggage is expensive. Thankfully my stay isn't longer so the baggage thing is doable.

The flight staff was efficient boarding people and were pleasant despite the close quarters, full plane and bumpy turbulence.

The boarding crew woman was completely and unnecessarily rude. I have a small purse I had gotten out of my backpack to get my boarding pass that she insisted I put back in my backpack before loading. I understand the concept and reason for the request but the manner in which she did it was so uncalled for. I don't recal a time in which I've been spoken to in that manner in a very long time. While I was doing it (it took literally 5 seconds), she was screaming at me to walk over to the side and lose my place in line. After I quickly put it in she screams it must go in all the way, which it was. There wasn't even a bulge from it and it closed with ease. I'd be happy to provide a picture of my small backpack/purse.

Watched a very weird interaction between Muslim (with a hajib) women with a kiddo and desk crew. She wanted to sit next to her child on the flight and needed to switch seats to be able to. Woman was very gracious and understanding that she was asking for an accommodation. Ends up her flight to Philly had been moved to a different gate after they had found a volunteer to switch seats. Volunteer was totally unfazed but Desk crew made it seem as tho the Muslim mom was at fault for the time and trouble they had had to go through to accommodate her. She apologized profusely and was very appreciative for the trouble evernote had gone to for her. . As she walked away the crew looked at each other and shook their heads. Pretty crummy way to treat customers!

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.

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.
