Hoover offered free transatlantic flights with any £100 vacuum — Britain did the math

In late 1992, Hoover's British division needed to clear warehouses in a recession, so it extended a modest promotion — free European flights with £100 of purchases — to include two round-trip tickets to New York or Orlando, worth around £600. The scheme's designers assumed the usual promotional physics: most people wouldn't buy, most buyers wouldn't apply, most applicants would be filtered out by a deliberately tedious redemption gauntlet of deadlines and unpopular travel choices.

Britain instead recognized free money. An estimated 300,000 people bought the cheapest qualifying vacuum — many never unboxed it — and pushed through every filter. Hoover's traps became the scandal: the company layered on restrictive travel offers hoping applicants would give up, a strategy the courts and press read as simply refusing to pay. Roughly 220,000 people ultimately flew, at a cost of about £48 million, while unsold vacuums piled up in a secondhand market that had collapsed under the promotion's own volume.

The fallout ran for six years: consumer groups, a Holiday Pressure Group, court losses, three senior executives dismissed, and the century-old US parent selling its European division to an Italian rival in 1995. British business schools still teach it as the promotion where nobody priced the scenario 'what if customers behave rationally?'
