2nd that Sandro, 300mm on a FF camera will have you miss quite a bit of stuff. For smaller acft (320s, 737s, 757s) you'd need about 500mm on a FF, 400 will do fine if you can use a 1.3 or 1.6 crop cam.
Drop Jorge Chavez & Paul Paulsen a line if you're going, brilliant guys and take one or two OKish photos too
