I know quite a number of airport codes, and kayak continues to disappoint on this end. For example, I type in CAN (Guangzhou Baiyun), expecting it to search that airport, yet instead it follows the beat of its own drum, searching Cancun (CUN) or even Akron/Canton (CAK). Same instance with wanting to search Guatemala City (GUA)-it brings up Guadalajara (GDL). In other words, that flight from CAN to Bangkok just got much more expensive.

Similarly, the atavists over at expedia decided to employ this method. As late as last year, I could type in an airport code and it wouldn't immediately show up as I am typing it-now, I have to confirm it first. That's inconvenient. Also, at least on Travelocity you can scroll down and very easily change dates and airport codes/point A& point B. Expedia, you have to go back to the home page. It still ceases to get my vote. Orbitz, that's a sleeper hit.
