What size luggage is 80 linear inches?

A piece of luggage measuring 80 linear inches typically refers to the total dimensions (length + width + height) of the bag. For example, a suitcase that is 30 inches long, 20 inches wide, and 30 inches high would total 80 linear inches. This size is commonly used for checked baggage on airlines, often falling into the "large" category. Always check specific airline guidelines, as size restrictions can vary.
