People in my office in SFO have been using RTW to beat the $6500 business class RT fare to most European destinations. On Star Alliance, these fares require 10 day minimum stays, however there are a few oneworld-esqe (BA, AA, CP, and QANTAS) fares that do not have minimum stay requirements.

My latest strategy for quick trips to Europe has been to fly via Toronto in business class. This cut my latest DFW-Europe ticket from $6200 down to $4200. Added several hours of travel, but I got to recharge my laptop.
