OK. So, I'm not a huge FF... I have some miles in all different places and am wondering what the best way of utilizing them to get from LAX to Germany (preferably in biz class) this summer (World Cup - yay!) would be.

I have 45K or so on UAL and NWA each, ~20K on AA, ~55K Amex, and 30K Diners. Maybe a few more here and there... Tickets right now look to be ~$1500 for coach. Any suggestions for putting these to use?

TIA
