15/13 could be the best possible schedule ever or it could be the worst possible. It all depends. One aspect is what kind of fleet you're on. I would imagine if you're actually really busy during those 15 days every single time, it would't be that great. I was lucky in that generally it was easy schedules, not flying every day and only the occasional redeye. If you're single, 15/13 is amazing! You're on the road doing your thing and then when you get home you're on a long vacation every single time. You have pretty much 13 uninterrupted off days to travel or do whatever. The main issue obviously is family. You have to have a really understanding spouse with kids. I don't really buy the whole "but I get to be home for 13 days with them". There's a huge difference between being gone for 3 nights on a 4 day trip vs being gone for 2 weeks. The spouse/kids will still remember you after 3 days. If you're gone for 2 weeks then you'll be that stranger that turns up again every 2 weeks, I mean it's definitely not a long term solution. I feel like if you don't have kids it's doable but with kids I say no way. That's just how I feel about it.
