This situation is probably one of the times that I think it's a legitimate recommendation for you to upgrade your camera body. You don't have to spend a lot, especially if you consider buying a used body from a reliable dealer.
I know a zoom is really handy for subjects that will be at varying distances but holy smokes, that AF Nikkor 300mm f/4 is a stellar performer and it works well with converters, too. I have the old D version and it might be too slow focusing for air show use.
