Tenerife Norte-Ciudad de La Laguna Airport, coded TFN and GCXO, is one of two international airports serving the island of Tenerife in Spain's Canary Islands. It is located near the city of San Cristóbal de La Laguna, in the northern part of the island, and serves primarily domestic and some European routes. The airport gained international notoriety as the site of the 1977 Tenerife airport disaster, when two Boeing 747s collided on the runway at the nearby Los Rodeos Airport — now the same facility — resulting in 583 fatalities, the deadliest accident in aviation history. Following this disaster, significant safety improvements and infrastructure changes were implemented. Today, TFN primarily handles Iberia and Binter Canarias flights, connecting Tenerife to mainland Spain and other Canary Islands. It operates alongside Tenerife Sur Airport (TFS) in the south, which handles the majority of international tourist traffic.
