**A strike at the heart of the summer season** From August 4, 00:00, the 1,179 employees of Groundforce Barcelona will begin an unlimited strike at Barcelona-El Prat airport. The CGT union has called the action over what it describes as an "unsustainable workload," excessive overtime, and insufficient rest for teams. The strike affects check-in, boarding, baggage handling, and flight coordination in terminals T1 and T2. The union warns that fatigue, stress, and the risk of accidents are sharply rising on the Catalan platform. **Which airlines and flights are affected?** Groundforce provides ground services for around twenty airlines, including Air Europa, Lufthansa, Air France, KLM, Qatar Airways, Etihad, Turkish Airlines, and United Airlines. Between early August and late September, about 11,600 flights operated by these carriers are scheduled at Barcelona-El Prat, representing nearly 2.4 million seats. The Spanish Ministry of Transport estimates that around two million passengers could face delays, cancellations, or baggage problems. The most sensitive operations are check-in, boarding, and baggage management, which are at the core of Groundforce's activity. The Spanish authorities have set minimum services: 58% of international flights and routes without quick alternatives, and 35% of domestic flights with ground alternatives under five hours, must be maintained. These thresholds reduce cancellations but do not prevent queues, cascading delays, or baggage bottlenecks. **Impact on flights to France** Direct flights between Barcelona and France, especially to Paris, should be relatively spared. Most Barcelona–Paris flights are operated by Vueling, while Ryanair serves several French cities without relying on Groundforce as its main handler at El Prat. For these two low-cost carriers, no massive flight cancellations are announced at this stage, but ground delays remain possible due to shared services or infrastructure saturation. Flights operated by Air France and Air Europa, which are Groundforce clients, are more exposed to disruptions at check-in, boarding, or baggage delivery. **Practical advice for passengers** Authorities and airlines urge passengers to check their flight status before heading to the airport. It is recommended to arrive earlier than usual at Barcelona-El Prat, especially for flights operated by Groundforce client airlines. Carrying only cabin baggage is advisable when possible, to reduce the risk of delayed or blocked checked luggage.
