Cancelled my flight TO Chicago. Next flight they could get me on was four days later! Then, lost my luggage on way from Chicago back to Portland. Agent lied to us that an agent had gone down to baggage desk to help us...we were sitting AT the desk the entire time and no one showed up. Now no one is available to discuss location / status of my suitcase, and the ETA. No one answers the phone at the number given to me. Poor, poor customer service.

The airplanes seemed new, and the flight back was on time.

Primarily the pricing is deceptive because things that included in the ticket price on most major airlines (e.g., 1 carry-on bag, a seat on the plane, soft drinks) must be paid for after buying the ticket. Fees just for a carry-on bag and selecting a seat on the plane added up to nearly $130 over the advertised ticket, and would have been more had I not checked in before leaving for the airport.

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.
