If you look every day many months ahead you can find good biz fares.
I often get biz to europe for 2,200- 3,000.
The best I ever got was 1800 DFW>DUS via ATLANTA on their new lie flat.

If all else fails read up on ASAP tickets in the forums. Some people like them, others don't. I have always been able to match or beat their price with daily searching and patience.
