The flight arrives safely into Denver

We had to take a bus to the plane. The buses the shuttled us on, they packed tight and without apology. We then sat in our seats for over an hour on the tarmac without explanation or apologies or any courtesy shown at all to the woman who dared to get up to use the lavatory and was scorned by the crew. When we got to our destination. The crew did not even apologize for the hour delay in landing or even mention it.

Airfare was $28 each way

No plug ins, hard seats, and an odd 20 minute delay to get a off the plane even though we were at the gate. They said it was because of the "balance". Really?

The pilot made up time after taking off late, the coffe and popcorn was good

The cabin crew seemed to do nothing but try and sell you stuff from blankets, credit cards, lunch boxes they spent a lot of the flight just trying to get you to buy stuff. When we landed we landed so fast the pilot had to brake very hard that life jackets came out of the pockets under the seats.

I got more room than most, sitting in the front row.

Skipped for drink service. My eyes were closed, I wasn't sleeping, but by the time I was aware of the steward, he was gone down the aisle and serving the people behind me. Also, even though I am disabled, the steward did not help me to put my bag up in the overhead compartment, even though he insisted, the very moment I sat down that my bag needed to be placed up top. No visible plugs for headsets, or USB to charge phones. This plane looks older than I am and I'm 47 years old!

I was charged to carry on my two bags. With added fees and taxes, it came to $168.20! The seats were very uncomfortable...not enough padding and way too crowded. They even charge for in flight snacks. Not a meal...the peanuts and soda you usually get free elsewhere. The flight attendant was rude to me. No wifi available for purchase that I could tell. Then at the end of the flight they had a big commercial-like announcement to push their credit card. It was very tacky.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
