The Great Western Challenge Regatta, air fares from Europe

I just checked yahoo travel, for what it's worth...

round trip from Frankfurt Germany to Ohare in Chicago, flying a couple days before and after the regatta, ~ $499.usd

4695

European Participants

As things get close I am intersted in a rough head count on sailors traveling from overseas, for both the Western Challenge and the World Championships.
Any help would be greatly appreciated.

the good rev.
