The high levels of ethanol in spirits slow the oxidation down tremendously. Unless you're taking over a year to go through a bottle I wouldn't sweat it. If you're worried about it, you could always transfer the spirits to smaller bottles after opening to minimize the air space.

I would say taking over a year to go through an expensive scotch isn't unreasonable if you have multiple bottles open.
