This comes from Second Front/War in Russia. Bombing airfields was the best way to win the air war, and other than the first turn it's much more effective than history would seem to indicate. Now there were particular planes that were great at strafing airfields and causing buckets of damage, the US P-47 comes to mind, but for the most case flying level bombers over airfields is a very hit and miss affair, mostly miss.
Even then, in most of the well documented effective P-47 raids, there was a lot of airfield damage and not a lot of plane damage. The real destruction of the Luftwaffe occurred when the disabled airfields were overrun by advancing allied armour, and the planes on the ground couldn't get away due to the airfield damage and lack of fuel (fuel depots having exploded in the prior attack). The real telling blow was allied bombing of the production facilities though, the ball bearing factory at Regensburg being the most well documented case although not the single most effective one. Once the Germans couldn't produce the planes to replace their air to air losses the war was over for the Luftwaffe.
Hmmm, the fuel thing yes, but the Luftwaffe had more planes than they could use in late war. The really scarce items were trained pilots and fuel.
