MIA 737I. 28 reserve lines. 21 have 4 sets of time off, 7 have 3 breaks.

If you have 3 breaks they'll be 2-6 days off each.
If you have 4 breaks they'll be 2-4 days off.

No trading of days off. What you see is what you get.

'G' - Golden days can't be touched ( ie you drop dead at midnight the night before).

M - moveable at the company's choice and not yours.

Non- golden day they can fly you until noon. So the first day off isn't guaranteed off unless it's a G (golden) day.
