Two weeks notice is the norm in this industry; don't burn any bridges unnecessarily. The only exception would be if FEDEX called me tonight for a monday class...I would give my resignation by cell phone on Monday, from Memphis.

If an employer is in the postion of needing someone in less than two weeks, they will tell you that up front, not leave you guessing. If they need you now or never, they will tell you that.

I have been offered ground school dates with less than two weeks notice, but have never accepted. In both cases they just offered me the next date that was 2+ weeks out.
