Ground-handling staff at Josep Tarradellas Barcelona-El Prat Airport represented by Groundforce walked out over unsafe working conditions and staffing shortages, affecting check-in, boarding, baggage, and ramp operations for 20 major international carriers. Spain's Ministry of Transport established mandatory minimum service levels requiring Groundforce to maintain between 35% and 80% of normal operations depending on the route, yet flight delays, cancellations, and baggage disruptions have persisted.
