Who Invented Rolling Luggage? The Story of Robert Plath

You are watching someone glide through the airport with a sleek rolling suitcase and it looks like that design has existed forever. It hasn’t. Rolling luggage was invented in 1987 — and the person who created it was not a luggage designer. He was an airline pilot who was tired of carrying his bags through airports.

The Answer: Robert Plath, 1987

Robert Plath was a Northwest Airlines 747 pilot who spent his career walking through airports with heavy bags. In 1987, he built the first Rollaboard — a suitcase with two wheels on one end and a retractable handle that allowed the bag to roll upright behind the user. He made the first prototype in his garage, tested it himself on trips, and then started selling them to fellow crew members who immediately recognized the solution.

What Existed Before the Rollaboard

Wheels on luggage technically existed before 1987, but the execution was poor. Bernard Sadow patented a rolling suitcase in 1970 — a horizontally-oriented bag on four small caster wheels, pulled by a strap. It wobbled, tipped over constantly, and never gained widespread adoption. The design was awkward because it rolled flat like a cart rather than upright behind the user.

For most of aviation’s commercial history, passengers carried their luggage. Literally carried it — shoulder bags, hand-carried suitcases, sometimes with a porter’s help. Airport terminals were smaller, checked luggage was more common, and passengers brought far less into the cabin. The idea that you would wheel your bag through the terminal yourself was not part of the travel experience.

Why Plath’s Design Won

Plath’s critical insight was the upright orientation. Instead of lying flat and rolling on four caster wheels (Sadow’s approach), the Rollaboard stood on two wheels with a retractable handle. This meant it tracked behind the user in a straight line, fit in overhead bins, and handled airport flooring without wobbling. It solved every practical problem that earlier wheeled luggage created.

Flight crews adopted it first. When passengers started seeing pilots and flight attendants rolling these bags through terminals, they wanted the same thing. Plath founded Travelpro in 1987 and the Rollaboard became the standard carry-on design within a decade. By the mid-1990s, every luggage manufacturer offered a version of the two-wheeled upright rolling bag.

From Rollaboard to Modern Spinner

Plath’s two-wheel design dominated until the early 2000s when four-wheel spinner luggage emerged. Spinners roll in any direction and stand upright without leaning, which is more convenient in tight spaces like airplane aisles and crowded terminals. But the fundamental innovation — a retractable handle with wheels integrated into the bag — is still Plath’s concept, evolved.

The timeline puts it in perspective: humans flew commercially for over 50 years before someone put functional wheels on a suitcase. It took a pilot — someone who walked through airports almost daily — to solve a problem that luggage companies never thought to address. Sometimes the best product ideas come from the people who suffer the problem most.
