Carry-on baggage must fit under a seat or in an overhead compartment. Briefcases and garment bags are generally considered carry-on pieces, though compact camera bags and purses may be exempted. Additional checked baggage may have lighter and smaller restrictions.
Most airlines allow oversize or overweight baggage or additional baggage for an additional fee.
Although most foreign airlines have stricter baggage restrictions, the piece method applies for most international travel to or from North America. The weight method usually applies for air travel outside North America. A maximum weight limit applies to all checked luggage and carry-on items. The weight limit varies by boarding point and carrier. For example, passengers paying the economy fare on flights from the Philippines are allowed just 20 pounds.
