In my experience, if you ask nicely and with a smile (which I know you would!), CMs do everything they can to make you happy. I don't see why you wouldn't be seated in the front seat, especially at such an early lunch time. (Just be careful. Last time we got to sit up front, the CM jokingly volunteered us to pay the check for the folks sitting behind us!) Have a chocolate shake and an onion ring for me, eh?!
