Linear inch is a phantasy word from the airliners. It means: X linear inches = length + width + depth (measured in inches). Inches are still inches. "Linear" inches are not made up. Inches refers to the measurement along a line as opposed to square inches (for area) and cubic inches (for volume).

Carry-on luggage should fit easily in this "Carry-on Baggage Check frame" which is approximately 22" x 14" x 9" (or 56 x 36 x 23 cm).
