British business travellers flying to Spain this summer face mounting disruption risks, with industry analysts warning that Palma, Alicante and Málaga could emerge as the principal flashpoints for delayed and cancelled departures during the May half-term and early summer peak.
Although the three Mediterranean gateways are not directly affected by industrial action at SAERCO-managed control towers, which began on 17 April and continues to disrupt regional airports including Lanzarote, Fuerteventura, Seville, Jerez, Vigo, A Coruña and La Palma, their position as the highest-volume corridors for UK traffic makes them uniquely vulnerable to knock-on disruption.
The warning comes as corporate travel managers are already grappling with longer queues and missed connections triggered by the European Union’s Entry/Exit System (EES), which moved into full implementation in April 2026. Spain has come under particular criticism for its handling of the new biometric border regime, with several other member states moving to relax checks at peak periods.
Jürgen Himmelmann, co-founder of Global Work & Travel and DealsAway, said travellers should not assume their itinerary was safe simply because their departure airport was not on the strike list.
“The risk for British travellers is not just whether their airport is directly named in the strike action,” he said. “It is whether the wider Spanish network is under pressure at the same time they are travelling.
“Palma, Alicante and Málaga are three of the airports I would be watching closely this summer, not because their towers are necessarily part of the SAERCO strike, but because they are major gateways for UK travellers. When you combine high passenger volumes, tight turnaround times, air traffic control disruption elsewhere and new border checks, these are the kinds of airports where problems can escalate quickly.”
He added: “Spain is still one of the most popular destinations for British travellers, but that also means disruption is felt at scale. A delay that starts at a smaller regional airport can have a knock-on effect on aircraft rotations, crew hours and later departures, especially during peak travel weeks.”
For corporate travel buyers, the implications extend well beyond inconvenience. Rotational delays caused by SAERCO walkouts at smaller stations can cascade into late-running schedules at Palma, Alicante and Málaga, the busiest UK-facing hubs, particularly during weeks when capacity utilisation is at its annual high.
Industry observers describe the combination of strike action, surging seasonal demand and an unfamiliar border control system as a “perfect storm” for travel managers attempting to keep executives moving on schedule.
With the Entry/Exit System replacing manual passport stamping for non-EU nationals, including UK passport holders, business travellers passing through Spanish airports are being advised to allow significantly more time for arrivals and connections, and to build greater flexibility into corporate itineraries until the new regime beds in.
