You thought Orbitz was a step up from Travelocity? (Priceline is too ghetto to be in the running.) Let Mobissimo blow you away. It is the best travel search site yet. Simple and clean, it serves up results fast.
Good timing since I am trying to buy a ticket to India my longest-yet flight on my own dime. My search did yield some good prices and lots of choices quickly with a minimum of clutter.
