But there's only so many flights we do, so to put another leg on you, is to take it away from another pilot. Its the same flights. There might be some minor changes, which to be honest, I'd rather do 18 hour 3 days, 4 of those and call it a month. What we don't want is less efficiency. Doing 10 hour 3 days will ensure we work right down to 13 days off trying to get the minimum window.
