FWIW, everyone I talk to is planning on bolting, even the senior guys. Just no where really to go yet. Given what's coming with duty rules most of the outstation bases are going to have be severely downsized or closed. Most of the super senior folks are in those places based at home. I expect the attrition will pick up from those high end guys once they are forced to commute. Upgrade is attrition and growth based anywhere you go. Airlines can barely see 6 months into the future, so what looks good today might be crap in 14 months and vice versa. 2012 will tell some of the story regarding upgrade.
