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.

Nice flight attendants, and the flight on the way home was not overbooked, which was lovely!

One flight attendant told me not to pack my bag so much if I wanted to take it on the plane, and I had to check it at the gate. Once on board, there were bigger suitcases than mine on board. I was happy to do what they said, but it would be nice if they were more consistent about the bag sizes. I didn't have this problem on the way back to Seattle though.

I would like to possibly see some better food options maybe for people who can not consume dairy. With the many different cheese platters, I was very uninterested. I had an early flight and thought I'd be able to eat something with a sort of substance. I was quite disappointed, I guess I'll have to be the annoying customer who brings chipotle on the plane next time.

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,
