Lens for Air Show shots?

[cfusionpm]

I'm attending an air show in a bit and was curious if my lenses will be up to par to get some good shots. Is it worth renting something like a 400mm L series or something? If so, where could I do that, and about how much would it be? Would my 70-300 IS be adequate? I've not shot planes/jets in action before and I want to be able to get some killer shots. Thanks in advance!
