I also don't see any way to search for non-economy-class flights...

as usual

First iteration.

I have never even heard of a flight search not supporting international flights.

Release early. Release often. Minimum viable product. Any of these ring a bell?

Come on, that would be like releasing an MP3 player in 2001 that had no wireless and less space than a Nomad.

Bad memories are now flooding through my head of silly complaints to various products over the years (a few of which I'm quite guilty of making).

Well, now you have! It's a much simpler problem to solve first.

And now you've actually used one.

For some values of "used." I used it to search for "toronto" then Ctrl-W'd.

You should have tried ITA Software's Matrix site in 2000. It was already awesome, but it was US only.

It's an obvious next step then. Their hotel search tool is US only as well: http://www.google.com/hotelfinder

I guess when they are combined into /travel they will be internationalized.
