Usually not a problem, the mil training (especially for tactical aircraft) is harder, so if you can get through that you can get through airline training. That's one of the reasons they like military pilots.

You as a fighter guy might be pretty busy compared to a transport type. I think the main cause of failure at majors is fighter guys who just don't get CRM...or refuse to get CRM.

Make sure you study up on basic 91 and 121 regs...airlines don't teach 91 regs or basic instrument flying, they expect you to know that when you arrive.
