FUN FACT: Aviation rules require that any plane carrying a parachute must have at least one for every person on board. Hopefully the reason is obvious.
Now given that, do you really want to pay the extra cost of flying with 300 parachutes just so mr-full-volume-phone can have one?
That is an incredibly fun fact. Does this only apply to commercial or also a little Cessna? Presumably there is no actual enforcement on the private planes.
I made it too fun: what I said was at best an over-genarlization. The actual rules [1] apply to acrobatics and say that parachutes are required for everyone when non-crew passenger is on the plane:
Unless each occupant of the aircraft is wearing an approved parachute, no pilot of a civil aircraft carrying any person (other than a crewmember) may execute any intentional [acrobatic] maneuver...
So without the passenger no one needs a parachute, with them everyone does.
It's perfectly legal for a 787 to carry a few parachutes just for the full-volume passengers.
Nah, with how ticketing is these days they'll bug you a dozen times to choose between the $50 basic economy disaster package that only has the mask and 50% airflow or the full package for $100 that includes another 25% airflow and a flotation device. Business execute gets you the parachute, a private life raft, and a few days of MREs for $250.
