Cool, but you could improve the user workflow. I have 2 airports tops I could leave out of here in San Diego. It doesn't help me at all that there are fares from Seattle to xxxxxxx. I recommend you ask me to enter my location and show me only relevant results.

Good idea. One issue I have is that I'm limited on the number of queries I can make to ITA for free. Google keeps jacking up the rates.
