The term hand luggage or cabin baggage (also commonly referred to as carry-on in North America) refers to the type of luggage that passengers are allowed to carry along in the passenger compartment of an aeroplane instead of moving to the cargo compartment or in other words, checking it in.Check-in luggage are larger pieces of luggage which are not permitted to be carried in the cabin of an aeroplane and have to be handed over to the airline for transportation in the hold of an aircraft, which means it is inaccessible to the passenger during the flight or ride. The dimensions and weight specifications for check-in luggage differ from airline to airline.
