What is the check-in/carry-on baggage allowance for domestic flights from New York to Los Angeles
Most if not all of the airlines in America have the same baggage allowance policies for both domestic and international travels. For Northwest Airlines check-in baggage allowance, traveling within United States or to/from Canada, Puerto Rico or the US Virgin Islands, with Coach Class Travel ticket, you are allowed up to 2 bags with size and weight limits of 62 linear inches and 23 kilograms, whereas for customers with First Class Travel ticket, 3 bags are allowed and the limits are 62 linear inches and 32 kilograms.
And carry-on baggage should not exceed 45 linear inches. Additional charges are applied for baggage weighing more than 23 kilograms or with a total linear dimension of more than 62 inches.
