Spain’s ATC strike warning
Spain’s air‑traffic controllers at SAERCO‑managed towers are planning an indefinite strike starting April 17 at 12:01 a.m., a move officials say could disrupt flights at about 14 airports. (express.co.uk) The duration is currently unknown, so travel managers warn this could be more than a one‑day headache and may affect routes to the Canary Islands and other holiday destinations. ( )
A strike by the people who clear planes to take off and land is set to begin across 14 Spanish airport towers at 12:00 a.m. on April 17, and the notice filed by the unions says it has no end date. The action targets towers run by the private provider SAERCO, not every airport in Spain, which is why some routes could be hit while others keep moving. (usca.es) The two unions behind it are the Union of Air Traffic Controllers and Workers’ Commissions, known in Spain as USCA and CCOO. They say the dispute is about staff cuts, heavier workloads, worsening schedules, and knock-on risks to operational safety. (usca.es) The airports named so far include Lanzarote, Fuerteventura, La Palma, El Hierro, La Gomera, Seville, Jerez, Vigo, A Coruña, Castellón, Burgos, Huesca, Ciudad Real, and Madrid-Cuatro Vientos. That list matters because it mixes Canary Islands holiday airports with mainland regional airports and a general aviation field near Madrid. (ftnnews.com) SAERCO is not Spain’s main national airport operator. Spain’s state-backed airport group Aena says it runs 46 airports and 2 heliports in the country, while SAERCO provides air navigation and airport management services at a smaller set of towers. (aena.es) (saerco.com) That is why the disruption risk looks uneven instead of nationwide. If your flight uses one of those SAERCO-managed towers, the tower staff are the bottleneck in the same way a single closed bridge can jam one side of a city while traffic on the other side keeps flowing. (saerco.com) (ftnnews.com) The Canary Islands stand out because four of the affected airports are there: Lanzarote, Fuerteventura, La Palma, and El Hierro, with La Gomera also on the list. Those islands depend heavily on air links for tourism and for domestic connections to the Spanish mainland. (ftnnews.com) This did not come out of nowhere. USCA said in December 2025 that it had already warned about staffing problems at SAERCO-run towers in the Canary Islands during the Christmas travel period, naming Lanzarote, Fuerteventura, La Palma, and El Hierro among the sites under strain. (usca.es) One report on the new strike notice says the staffing gap is close to 30 percent. If that figure is accurate, it helps explain why the unions are describing this as a structural problem rather than a short pay dispute. (tercerainformacion.es) An indefinite strike does not always mean every flight stops. Spain’s Transport Ministry regularly sets minimum-service rules for transport strikes, which can force part of the operation to keep running even while delays and cancellations pile up. (transportes.gob.es) For travelers, the practical problem is timing. A one-day strike can be dodged with a rebooking, but an open-ended walkout starting on April 17 can keep spilling into Easter and late-April travel plans if the two sides do not settle fast.
