62 linear inches explained
"62 linear inches" means the length + width + height of your checked bag, measured with wheels and handles, must add up to 62 inches (158 cm) or less. A 27 × 21 × 14 in suitcase is exactly 62. It is the standard checked bag size at 20 of the 25 airlines we track.

Suitcases sold as "large" or "29-inch" usually break 62 linear inches and pay an oversize fee on most airlines, typically between 63 and 80 inches. Allegiant is the exception, allowing 80 linear inches as standard. See checked bag limits by airline.
