I think the important number is how many days we are home or away, does it make that much of a difference if you're gone half a month and block 10 or 50 hrs in a month? This is why schedule flexibility is so important, I can work as much or little as I want. If I want to take 2 weeks off, i can drop the trip and take a hit in pay. I was able to drop 100% trips and pick up at 200% trips over the summer, which means i can maintain the same days off or more with more pay. We have CA who live on a boat and do just a 4 day trip a month, or a pilot who commutes from Alaska and leaves for 9 days and take the rest of month off. We have CA who credited over 280 hrs in 1 month, or those who live in base and does mostly day trips and only gone 2-3 nights out of the month. Our numbers will be all over the place.

Come on now, how many time zones do you cross and how long does it take to get back to normal once you are home? I would think that's worse than my 1.5 hrs commute where I can barely finish a movie, plus the 117 rules makes a big difference.
