wow thank you for your insight : ) thats great!!! i might rent one or i'll buy a 2x extender...and you are right it's not a big airport. but still like what you said it's like 1000 feet away. thanks flyingphotog.
I've rented the Canon 2x and I own the Canon 1.4x. I've used the 1.4x on a 70-200 f/4, 400 f/5.6 and 300 f/4 and it is superb. You'll hardly know it's there if at all.
I don't recommend the 2x extender, at least on the lenses I mentioned. It is best, as I've read on the Canon L prime telephotos, not on lesser lenses as it degrades quality too much for many peoples taste; YMMV.
I'd look into renting a 100-400 or 400 f/5.6 like someone mentioned as those will give you better pics than the 70-200 with 2x. The 10-400 will give you more versatility especially if there are static displays you want to shoot.
