Just my 2 cents: I left a regional after many years to go to World. Can't speak for any of the other ACMI's but I am very happy I did it. Don't know what the future holds but who does. Personally I'm not worried about it, World has been around for 60 years but I just hope they are around another 20. The flying is great, the crews are great, and I personally like the schedule. Two weeks off every month is fantastic.
