Saying that Boeing execs all travel by private jet is bollocks! Maybe Condit on a 'state visit', he'll turn up on a 737NG-BBJ but believe me everyone else flies commercial. For god's sake, why wouldn't they? It's hardly necessary for salesmen, auditors, safety specialists, consultants etc to fly in a private jet when their equivalent numbers at, say, Starbucks fly AA, UA, NW etc.
It never occurred to me but I bet it is a pain in the arse for Boeing people (and expensive too) to have to fly to Seattle, adding a couple of hours extra to their journey time every time they hit the road. Moving the corporate HQ out of WA makes loads of sense to me, for many reasons stated by other contributors but primarily the cost of travel. The electricity question is an interesting one as well.
fly Saha Air 707s daily from Tehran's downtown Mehrabad to Mashhad, Kish Island and Ahwaz
