why would it not be leagal? its just easier for the flight attendants for passengers to use credit cards. alot of times there is no change for the flight attendants to give back to you right away (buying a $2 can of pop with a $10 bill). its just easier this way to eliminate the cash on board and paperwork to turn in when they get back into the base. thats all it is. if you dont like it, use your cash and by a bottle of water or pop in the airport.
