Northwest Airlines suing gonorthwest.com.
http://blog.seattlepi.com/aerospace/archives/175612.asp
"...Northwest Airlines, the major airline that has been acquired by Delta, charges that it has exclusive ownership of the term "northwest." The Minnesota-based airline is going after the operator of the Web site gonorthwest.com, which provides tourist information for visitors to the Pacific Northwest.
Although Delta Airlines has purchased Northwest and is slowly eliminating the NWA branding, the issue has only escalated. High's attorney speculated that the Northwest Airlines attorneys have gone "
rogue" in look for work in the down economy."
