Tenerife Norte-Ciudad de La Laguna Airport — Tenerife, Spain

Tenerife Norte Airport, coded TFN, sits close to San Cristobal de La Laguna on the northern side of Tenerife in Spain's Canary Islands, at an elevation that leaves it more exposed to cloud cover and fog than its southern counterpart. Under its earlier name, Los Rodeos, the airport became the site of the deadliest accident in aviation history on March 27, 1977, when two Boeing 747 aircraft collided on the runway in dense fog, a tragedy that reshaped international standards for airport communication and runway procedures. Today TFN handles predominantly domestic and inter-island traffic, connecting Tenerife to Madrid, Barcelona, and the other Canary Islands, while Tenerife Sur to the south absorbs most of the archipelago's international tourist charters. The airport sits nearer the island's historic university town of La Laguna than to the southern resort areas.
