Iberia strike over holidays to cancel 444 flights across 29 Spanish airports

Four days of strikes beginning Friday will ripple through Spanish aviation during one of the year's busiest travel windows. Three unions—UGT, CC OO, and USO—have called ground workers at Iberia Airport Services to walk out January 5 through 8, and the airline has already announced 444 flight cancellations across 29 airports. The dispute centers on a contract decision made last September that will reshape how baggage gets loaded, passengers board, and aircraft are serviced at Spain's major hubs.

The conflict traces back to Aena's decision to reassign ground handling services—known in the industry as handling—to competing companies at all but one of its airports. Iberia Airport Services, the airline's ground operations subsidiary, lost the contracts for major airports including Barcelona, Palma de Mallorca, Málaga, and Alicante. Only Madrid-Barajas remains in Iberia's hands. The new contracts will go to Groundforce, Aviapartner, Menzies, and Swissport, companies that will take over the work beginning in 2024. With that transition comes a legal requirement: roughly 3,000 Iberia ground workers will be transferred to the payrolls of these new contractors through a process called subrogation. The unions fear this shift will erode wages and labor protections, and they've demanded that Iberia keep these workers on its own books, even if only for self-handling operations—servicing Iberia's own aircraft.

The strike's reach extends far beyond Iberia itself. Although the walkout targets Iberia Airport Services, around 90 airlines depend on the company for ground support at those 29 airports. International carriers, regional operators, and budget airlines all stand to lose flights. The major exceptions are carriers that handle their own operations: Ryanair, easyJet, and Air Europa will continue flying normally because they don't rely on Iberia's ground crews. Within the Iberia group, the airline plans to cancel 270 flights, Iberia Express will lose 64, and Air Nostrum will drop 110. Across the group, Iberia expects to operate 836 of its 1,106 scheduled flights—a 76 percent rate—with nearly all long-haul routes preserved. Iberia Express will maintain 88 percent of its schedule; Air Nostrum, 72 percent.

The human toll is immediate and concrete. Forty-five thousand six hundred forty-one passengers have reservations on flights that will be canceled. Thousands more will face delays retrieving luggage, boarding, or deplaning. The timing compounds the disruption: these are the days when families reunite after the holidays, when people return to work, when travel plans made months in advance finally come due. Iberia says it has already found solutions for roughly 91 percent of affected travelers. The airline relocated 36,621 passengers—80 percent of those directly impacted—to other flights. Another 4,900 passengers accepted refunds or date changes rather than endure the chaos. Passengers with unaffected reservations can also request to change dates or receive travel credits. The airline has reinforced its customer service lines, though wait times will likely stretch longer than usual. The phone number from Spain is 900 111 500.

Compensation is available under European Union law. A 2018 ruling by the Court of Justice of the European Union established that airline strikes do not qualify as extraordinary circumstances that exempt carriers from paying damages. Passengers on canceled or significantly delayed flights can claim between 250 and 600 euros depending on distance: 250 euros for flights up to 1,500 kilometers (or 125 euros if an alternative flight departs within two hours); 400 euros for flights between 1,500 and 3,500 kilometers (or 200 euros with a delay under three hours); and 600 euros for flights exceeding 3,500 kilometers departing outside the EU (or 300 euros with a delay under four hours). Beyond compensation, passengers are entitled to a replacement flight, a full refund if they decline it, and reimbursement for any expenses incurred during the disruption—meals, hotels, lost baggage claims.

Iberia's position is complicated. The airline agrees with the unions that Aena's decision was wrong and has appealed the contract award to Spain's National Court, requesting that the new contracts be suspended. Yet the company has rejected the unions' demand for self-handling, arguing it is not economically viable. Iberia maintains that the sector's collective bargaining agreement protects the wages and conditions of workers who transfer to new employers. The company has called the strike "irresponsible," particularly given the timing during a period when families reunite and people exercise their right to vacation.

With the strike set to begin Friday, the chances of a last-minute resolution appear slim. Management and unions have held multiple meetings this week without reaching agreement. Even if the strike were called off partway through, Iberia has warned it will not reschedule the canceled flights. The logistical complexity is too great, and passengers have already been rebooked or refunded. The dispute will likely play out in court and at the negotiating table long after the holiday travel season ends.
