An add on to the 'board early' mantra: once you have status and are getting bumped to first class, always be the last person to board. The flight attendants don't let the steerage folks poach your overhead bag space and there's still no reason to board early and sit in the sky bus for any longer than you have to.
The drinks you're drinking in the lounge or bar on the expense account are just as free as the tiny cocktails on the plane.
