Airlines are interested in pointy nose guys especially now because of the hiring climate and decreased number of qualified candidates. There are a lot less former military pilots available due to smaller military size than in former hiring booms. 5-6 years ago there were a fewer single seat guys as a percentage of new hires at the majors.
Yes if you can learn to fly a tactical jet, you can learn to fly an airliner. But also yes airline training is more challenging for single seat guys. In fact, I’d say that as a group, they have more issues and problems during airline training than other groups except for helo pilots. This is why when hiring times are lean, more multi engine big plane guys get hired at airlines than single seat pointy nose guys. Airlines like guys who fly the same type of planes better.
Airlines also like more hours over fewer hours. They realize single seat guys have less and maybe their hours were more challenging but in event of a tie, more always wins. Big plane military pilots tend to have more hours than single seat military pilots.
I’ve watched and lived airline hiring for 20 years. I’ve seen the cycles. Barring another 9/11 type event, a recession, etc. you are correct - pointy nose single seat guys will get hired at majors. However that can change with another downturn in airline business.
I’d also hazard to bet that after Helo pilots, there are more single seat guys having to spend a year or two at a regional than there are big plane military guys.
Bottom line - today you are right and for the foreseeable future you are right. But down the road who knows what the majors will need for pilot hiring. History tells us the big, multi piloted and multi engine guy has the advantage. It’s not criticizing single pilot guys, it’s just the way it is.
