It really depends on the market you want to be in. If you want to fly 737 at a lowco that could be an issue as there is a surplus of type rated no hours guys around, but if you don't mind flying frieght in Nigeria or working out of Europe it may be a different story. We have just arranged a type rating for a 47 yr old nil commercial hrs guy on the 747 classic and he has a job on freighters secured after base training.. why maybe because he doesn't mind where he works, isn't worried about command and probably is good company on the long freight legs! Horses for courses.
