I'm a dispatcher in search of a flying job. I'd definately recommend it. I've got some valuable experience which would take anyone several years on line to pick up. My position is not what I want, but I'm very lucky compared to most other flying job seekers out there.
Anybody in my situation, I'd definately go for it. It will stand to you and its great for keeping your knowledge of met, planning performance, ops etc up to speed. Meanwhile I just grab a rented cessna to keep current. Still my fave.
