The Biscoff cookie, known as the plane cookie among generations of Americans, has become a cherished part of air travel culture. Fun fact: 'Biscoff' is a portmanteau of the words 'biscuit' and 'coffee. ' They're only branded as Biscoff in North America and are known as Speculoos Cookies everywhere else.

The most famous airline cookie is the Lotus Biscoff, a crunchy, caramelized shortcrust biscuit (speculoos) that has become synonymous with air travel. Originally from Belgium, the cookie was introduced to the skies in 1985 through a partnership with Delta Air Lines. Its popularity is rooted in its unique flavor profile—a blend of cinnamon, brown sugar, and ginger—that remains distinct even at high altitudes where the human sense of taste is naturally dulled by cabin pressure and dry air. The name "Biscoff" itself is a portmanteau of "Biscuit" and "Coffee," reflecting its intended pairing. In 2026, Biscoff remains a staple on Delta, United, and American Airlines, with over 6 billion biscuits produced annually. Its status is so iconic that it has inspired "cookie butter" spreads and even airline-specific merch. For many travelers in 2026, the sight of the red-and-white individual wrapper is a nostalgic symbol of being "en route" to a new destination.
