Unless the a/c was at a remote stand with stairs no one would probably see you as I am assuming they would just drop you off at the steps on the metal air bridges and escort you up the metal stairs at the side.

The CC wouldn't be any the wiser as they wouldn't be able to see you until you are at the door of the a/c or am I missing something!?

I like your enthusiasm though and life is for living so why not?
