I punch air all the time. Because it travels really well. It's with me, right there, all the time. Bags aren’t, or partners with mitts, shields, whatever. And sometimes, there's just nobody around to train with.
Keep in mind - when you punch air, you are punching at the exact distance and height that is one hundred percent comfortable to you, the exact height, distance and power that makes your punches feel the best through their ideal level of distance, height and technique. It is the natural place your punches come from.
Which is why you have to always change their level. You don't throw punches at a 6 ft 5 guy the way you would at a 5 ft 6 guy. When you air punch, you should mix it up, constantly.
