Just saw this thread, so sorry if it's a bit late. I would run, not walk away.
I was a captain/instructor/babysitter on one of their Challengers. There isn't really anything good to say about it, except the expat pilots and FA's are a good group, but nobody stays more than a couple of months.
They've been using ACASS Canada for recruiting for some time, and in an effort to save some money, have tried to hire directly and use other recruiters. I was a direct hire. I thought I was pretty slick to avoid ACASS, but at least the ACASS guys got paid on time.
The Libyan pilots will try to kill you on every flight. They will conspire with the Libyan FA's to steal tip money. There are all the usual frustrations with working in a third world socialist dictatorship, along with ****ty maintenance, no schedule, no duty rules, and actually no AOC. The Libyans are always running afoul of customs outside of Africa because they never have the required visas or a valid crew ID.
