I'm still looking for the best way to search for fares to Europe. There are lots of possibilities for departure and arrival airports for me, I live near SFO, OAK, and SJC and want to get into Central Europe. My dates are also somewhat flexible (but my wallet is unduly light.)
Anybody know how I could search from multiple departure airports to multiple arrival airports with flexible dates for the best fare? The end destination for me is Cologne, but I'd like to spend some time elsewhere too: perhaps Warsaw, Berlin, Prague, Budapest, somewhere in the Netherlands, or something like that for fun too.
Any thoughts?
