I am currently working for a charter with a 20/10 sched. The 10 days are consecutive and the eight in the middle of the 10 are hard days off. So, we get a vacation every month. We fly on average 13-15 of the 20 days on. If something pops on the eight hard days off, then we have the OPTION to fly it if they need us and we get bonus $$$ to do it. If we turn it down, they have no issues getting a contract for the trip. We also had the option for a 14/7 schedule, but we wanted to leave it like it is. 20 days on is a long tour, but I really like being able to plan on having a 10-day monthly vacation. I think the mentality of management is key. Ours is great.
