I want to go jfk-dbv in late june on either a reward or $+miles ticket (biz, j?) but i dont even know where to start. My head is spinning on where i should fly into and how i should get there. Is it best to fly to lhr and then onto dbv, best to fly into VIE? What airlines are my best bet for using miles ? Any help would be great. Please tell me where to start.

PS-I have SPG points so im looking to xfer from there.
