Well, you cant stay in the air all the time when your airfield is not in shape. We dont talk about hours, we rather talk about days or even weeks.
Its more likeley that your airplanes are at the ground and cant start when the weather conditions are bad. So maybe your airplane units should be grounded during bad weather, so that the enemy can attack them with ground units. Like in early barbarossa, when most of the russian planes are ground units.
If your airport is gone, you have to conquer it back to be able to use your planes again.
But dont get me wrong, that is not a feature that needs to be changed. Just some thoughts...
