Obviously you're going to have to figure out what works for you. We'got 550+ pages saying this is not a 3 on/4 off 4on/3 off airline. I will say about half the lines in the JFK bid packs have been 60 day lines. The 60 day lines have you going to work three times. This month and next I'm only working 15 days. Three off, work 6, 12 days off, work 14, 7 days off, work 10 and 8 days off. I don't know if the other bases have as many 60 day lines.
