How about a PA whilst taxying in asking that passengers open the air vents when they leave their seats? How bloody simple.
Good idea, but I have a feeling it would have as much effect as the PA which states "Please keep your seatbelt fastened until the aircraft has come to a stop at the gate and the seatbelt sign has been switched off".
As soon as the thing turns into the bay, every man and his dog is out of his seat, opening lockers, getting ready to disembark even though the engines are running, belt sign still on and all the rest.
Why are people so self righteous when it comes to these sorts of things??
