747 type without the turbojet 121 pic is not worth much. Some guys manage to get there without it but I’d say they are the exception. if you had a couple thousand in the left seat of an Rj and still nobody calls maybe a heavy type will help but 121 pic is the gold standard for career progression. Even if you did upgrade at Atlas in 3 years (which you probably won’t)it would take a few years to get a 1000 hours pic. better to have it before you come.
