i've often wondered about this as well. Perhaps a solution is to keep 3 months salary in a savings account to keep you going during a slowdown, maybe I'd need 6 months worth of savings to sleep well. But it does look like more fun than being locked into seniority systems with the benefit of being able to travel the world properly, by working and socialising with the locals.
Anyone have experience of how long the lean periods can last if one has good jet experience? It would be nice to go into it knowing what the worst case scenario may be
Cheers,
