KLM's New Flying Fries Defy Altitude Odds in Business Class

KLM Royal Dutch Airlines has launched a notable addition to its business-class catering that addresses a persistent challenge in airline food service — achieving crispy French fries at cruise altitude. The carrier is now serving what it calls "Flying Fries" as part of its Sky Break mid-flight snack service on long-haul routes.

The fries arrive in a specially designed blue KLM-branded box that doubles as the cooking vessel in the aircraft's convection ovens. This packaging approach reportedly produces results that maintain the desired crispy texture, a feat that has eluded many carriers. The product is manufactured in the Netherlands and features what travelers have described as a straightforward ingredient list, containing 247 calories per 100-gram serving.

The snack is accompanied by traditional Dutch Zaanse mayonnaise and tomato ketchup, reflecting the airline's national culinary identity. KLM serves the fries as part of a structured mid-flight service rather than on an à la carte basis, with cabin crew distributing the Sky Break menu items in coordinated aisle service.

French fries have proven difficult to execute successfully in the airline industry. Major U.S. carriers including American Airlines and United Airlines have struggled with the offering, while Delta Air Lines opted to serve potato chips alongside its Shake Shack burger partnership rather than attempt fries. Some Asian and regional carriers have achieved varying degrees of success, though texture consistency remains an industry-wide challenge due to the low-humidity cabin environment and reheating limitations.

The Sky Break menu also includes other Dutch-themed items such as stroopwafel ice cream. The fries offering notably does not accompany KLM's previously established burger service, which runs as a separate menu item on the carrier's long-haul flights.
