As a safety measure, certain items are allowed in checked baggage, while they are banned from cabin luggage. These items include snow globes, box cutters, swords, baseball bats, saws, martial arts weapons, ammunition and firearms. Other items are prohibited from being transported on a commercial airplane at all, including gun powder, gasoline, lighter fluid, spray paint, flares, fireworks, fire extinguishers and replicas of explosives of any kind.
Airlines--such as Air Canada, British Airways and Delta--generally restrict passengers to one piece of cabin luggage and one personal item. Small suitcases, laptops and diaper bags are examples of cabin luggage. A personal item is considered a small purse, a small camera bag, a coat or an umbrella. Delta Airlines restricts cabin luggage to no more than 45 inches total when the length, width and height is added up. Air Canada limits cabin luggage to no larger than 9 inches by 16 inches by 22 inches.
Airlines like Air Canada, British Airways, Delta and Qantas restrict the number of pieces of luggage and the weight of the luggage according to the class of the airline ticket purchased and the travel destination. For example, most economy tickets on British Airways entitle the customer to one free baggage allowance up to 23 kg., while most first-class tickets on the same airline entitle the customer to three free baggage allowances up to 32 kg.
