I've was a new hire straight into the 756 fleet. Pretty much everything people have said is accurate. 1 1/2 years on reserve, although I'm lax based now. If I was in Sfo I would maybe hold a line. One thing I will add though is if you get the 737 and really don't like it and decide you would rather for some reason sit reserve on the 756, then you can bid up to it. You CANNOT bid down to the 737 if your on the 756 for 2 years though. Big advantage to go 737 or airbus.
