Searching for flights on the internet has always been kind of easy. But the various interfaces, data entry fields, and numerous sites you have to go to (unless you use Kayak) to find them have never made it a joyful experience, exactly. Google wants to change that. Now, you may already know Google publishes a flight search app called OnTheFly by ITA. It's pretty good on a phone. I've used it to help friends book flights before, and I really like it.
But on a tablet, the app has tons of wasted space, and just doesn't feel like it's optimized for the big screen.
