On the first leg of my trip, the time shown on the boarding pass was the time I needed to be at the gate. For this leg of the trip, the time on the boarding pass was the time the plane left. I arrived at the gate at the time the boarding pass said and the plane had already left. I am traveling to my father's funeral and the only option I had was to rebook for an additional cost of $600. Extremely upset.

Plane staff was friendly, onboard entertainment options were good and the fare was reasonable.

Plane noise was very loud and cabin temperature was so warm I was sweating and my wife ended up feeling naseaus towards the end of a 5.5 hour flight. Also, not a big fan of advertising being played over the TV and cabin speaker system.

Super nice flight attendant. Really made all of us (business travelers, retired military folks, family with little kids heading to a wedding) feel welcomed and happy. Great experience.

I began asking for my wheelchair escort the minute I got off the plane. I was assured in Houston they would be there when I got to Detroit. They were not. The request was clearly spelled out on my boarding pass along with my personal oxygen equipment information. I kept asking different staff and they would call for me then say somebody would be there. I waited for an entire hour and only when I started to cry did somebody do something. It was terribly stressful.

Everything is good except our lunch as described below.

They ran out of chicken breast in our lunch packages, so the stewardess went back to get it. After 10 minutes she still did not show up, we turned on the help light, and still no one came. Finally she passed by and we reminded her the 2 chicken breast lunch packs, she said : "Sorry, I've forgotten about them" and ran back to get them for us.

The snacks were decent on the flight. Everything else was a disappointment.

Unexpected delay for take off after being told the flight was going to be on time. They couldn’t give us a reason or an eta on take off while waiting at the gate which affected my ride situation once I landed in Seattle.

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,
