Adding a perk for these guys isnt going to help. Most of the guys flying them have thousands upon thousands of perks. Resetting the perks each month/quarter/semi annually those combined might help.
5 guys in uber planes gang a lone guy because kills are hard to come by. 5-10 kills a sortie wasnt tough to do in the old days as we had good numbers. Today your lucky if you spot 5 guys a sortie and 3 of them will run away unless they are at 20k+
Most of these guys who fly the temps/yaks/190s are not all that good. Their egos couldnt handle flying a mid-war plane and dying or not getting half a dozen kills per sortie. Personally Im not very weary of high fighters, but a low mid-war plane scares the heck out of me.
For a lot of these guys they either want a good score, or want to land big numbers. In it for the challenge? Nope, not a chance.
As for flight time, In most planes it takes less than 5 minutes to get to 10k, less than that to cover a sector. That is barely enough time to get a drink or snack let alone go pee! Of course if you feel the need to climb to 20K+ I can see why you might complain.
