It's not Canoe
I used to have a major problem -- I couldn't remember the name of this site. I would try canoe.com, and other similar names. But the correct name is http://kayak.com, and it's finally sunk in.

Kayak is an incredibly simple, yet supremely powerful way to search for airline fares. Think Sidestep without the nasty spyware, and also faster and sleeker. Unlike the big boys like Orbitz and Expedia, it includes searches on airlines like JetBlue, Virgin America, and other "newer" airlines. They also have options to search for hotels, cars, "deals" and vacations, but I can't vouch for any of those.
