I recalled that I saw this issue somewhere that airplanes in the reserved hangar is still used for alliance mission allocation. If this bug still exists, does it mean that I can almost never get alliance missions for middle tier airplanes? My current configuration is 4 turbo, 4 jets, 1 delta and 1 powerful detla. I am going to buy higher airplanes. But if this bug holds, it means I can almost never get alliance missions for delta because it is natural to have less high level planes. Middle tier planes cannot be assigned for neither mission 1 nor mission 2. But you have to buy planes to make it for mission 2.
