Travel: Something to declare - True or false

True or false: "You can drink as much as you like on a plane"

False: "The aircraft captain has the legal authority to refuse boarding to any passenger that he or she considers unfit to travel, and to anyone whose behaviour or condition, under the influence of alcohol or drugs, may be a threat to the safety of the aircraft, passengers or crew. Airlines may also deny boarding to any passenger whose presentation and dress may cause offence to people of other religions or cultures. If a passenger becomes disorderly during a flight, the captain is entitled to land at the nearest airport and have him or her removed from the aircraft." - Thomson Holiday Guide, Summer '97
