Spain air traffic strikes disrupt 20,000 flights through May 31

What’s happening at Spain’s airports

An indefinite strike by air traffic controllers at Saerco-managed towers has been in effect since April 17 and is still disrupting operations at Seville and eight other Spanish airports. The Ministry of Transport’s minimum-services order runs through May 31, so service is continuing, but not normally.

The dispute centers on understaffing, safety concerns, rest violations and working conditions, according to the unions USCA and CCOO. Affected airports include Seville, Jerez, Madrid-Cuatro Vientos, Vigo, A Coruña, Lanzarote, Fuerteventura, La Palma and El Hierro.

Who feels the disruption most

Tourists, expats and digital nomads are seeing the biggest impact at regional and island airports, where there are fewer rerouting options. The Canary Islands are especially exposed because alternatives are limited and Seville can be hit hard during major events like Feria de Abril.

Airlines are dealing with delays, cancellations and knock-on crew issues. Strike trackers estimate the first month could affect 2.6 million to 2.95 million passengers and about 20,000 flights.

What travelers should do now

Check your airline and airport before heading out, then keep an eye on rebooking options if your flight is delayed or canceled. Under EU 261, airlines must offer refunds, rerouting, meals and hotels when needed, though compensation isn't normally due because an air traffic strike counts as an extraordinary circumstance.

If you’re traveling between mainland cities, rail or road may still be a workable backup. For island trips, though, flexibility is much thinner, so plan extra time and watch for daily service updates through May 31. Read our full Spain guide for the complete picture.
