Opportunist
Oh dear, looks like any ticket search site will have to watch out for the same case against them.
If you're searching for air fares or any other ticket price then there's certain information you need. There's only so many sane ways to present requests for that information.
A quick search for fare searching sites will show you a half-dozen who ask for, surprise surprise, the same information. Kayak are just going after MS because they figure they've got money, and might have the courts on their side.
