The carrier already gives you 1 extra move since don’t have to take off from land. Really, 2 moves, since you also don’t have to transition back to land…in some situations.
Planes already move pretty dang far, 5, 6 moves gives them a lot of freedom.
Don’t some rules already exist regarding bombing, ie, interception, and that an AB can support a scramble against an adjoining amphib invasion territory.
