I would say 6.5 weeks from indoc to IOE. On reserve you will get 76 or 72 hours of block depending if you are long or short call reserve. On the 73 in EWR, the average line value for FEB. was 89 hours. I'll be a lineholder for March. I was on reserve only for one month. If you are awarded the 756, you have to wait 2 years to bid back down to a 737.
Good luck!
