Travelzoo bought and has now relaunched Fly.com - looks familiar

Email/Deals marketing firm Travelzoo (TZOO) bought the domain name Fly.com for US$1.76mm a week or so ago (more over at Travolution). Today I saw a story announcing that Fly.com has been relaunched as a meta-search beta. New model for them. I wonder where they got their inspiration. Here is a screenshot of the new Fly.com website. Free 1 year subscription to the BOOT for anyone who can tell me which site the Fly.com website looks the most like. Any guesses? There is a hint below.

Update - just saw a post from Tom Botts of Hudson Crossing where he reviews some features from Fly.com
