As a guy who works for a regional which recruits pilots who are out of currency.. Aka who've not flown in years.. I can fully understand why they want you to go elsewhere to get current. Years outside the cockpit, plus having never worked in a 121 environment can mean a lengthy training footprint and or washing out. If you can pick anyone you want to hire, you don't pick a guy who's likely going to take more training.

My company has outstanding training, but I can tell you first hand - as a LCA, we spend many hours on folks who haven't flown in years. Most Military guys come here, fly for a year or two then get picked up.

Just remember you have folks with 10,000+ hours and Impressive resumes who are also at these companies and want that job. So I'd keep it to yourself that you think getting current is all you should have to do to get the job, if that's how you feel.
