Hurts that the Axis start with 12 fighters, 2 bombers between two nations, don’t it? (I’d count the allied ones, but most of those are destroyed on Round 1. :P)
I believe the trick is to force the Axis to break up their fighter formations over multiple territories, OR, attack territories with AA Guns. Though, I am always happy when I can take ou German Panzers even if I cannot get their Stutkas.
