Thank you everyone for replying! I appreciate your help.
I work for a NWA regional carrier. I know that i can jumpseat with US 121 carrier or buy a ZED fare for anybody else we have agreements with.
I don't really want to take any US carrier though...as their service is pretty horrible...i've heard of great things about Lufthansa, Air France and KLM...so that's why i posed the question...looks i'll be ZED fare'ing it with one of these airlines.
Thanks again to all!
