The fact the flight was only a bearable 2 hours

The ticket was $30, but then taxes and fees were $43. That's just the start of the money trap...to have a carry on- $60 To check your bag- $45 Then to "reserve your seat" it's any where from $14- $30. The seats didn't even recline. Then during the flight everything costs money, even WATER! I will never fly Frontier again unless I'm desperate...I mean, REALLY DESPERATE!

Premium economy is a must for me from now on. I am 6'4" and the extra leg room makes all the difference in the world. My flight was at night so I had little interaction with the crew. Overall I had a very pleasant experience on united and would definitely fly with them again.

Food options were limited to snack boxes. I had a layover in Denver. At the time of my arrival all of the food options in the Denver airport were closed. I would have appreciated some more substantial food offerings on the plane, as I had to go without dinner thatnight.

I enjoyed the in-flight staff's quips and banter, the easy access to power outlets, the possibility of free access to movies and tv (I found it too late in the flight to finish a whole program before landing).

The Games section of the screen entertainment is a bit lacking. Pre-flight, I would be interested in a reminder email about empty seats that are 1) in a window seat (or whatever other seat you desire but may not already have), and 2) not seated next to any other passengers-it'd be nice to be able to sit alone, when possible.

There was one flight attendant who was very nice.

Upon arrival we discovered that our seats were separated. This includes my husband, two year old on her first flight--and myself. The attendants acted as if there was nothing they could do. We were one of the last passengers to board the plane and everyone was settled in. We blocked the isle for the last several people trying to get to their seats which was very embarassing and uncomfortable when they had to squeeze around. It was up to us to ask fellow passengers if they'd mind swapping seats with us. We knew putting our two year old between two strangers would have made for a miserable flight for everyone. Finally a couple passengers agreed. Thank goodness for their kindness.

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.
