Spain's state airport operator, AENA, plans to limit passenger numbers at Madrid Barajas and Barcelona El Prat airports beginning in the summer 2027 season [1, 2].
The move comes as Spain faces record tourism levels and evolving border regulations that strain existing infrastructure. By capping the number of travelers, the operator aims to prevent overcrowding and maintain operational efficiency at the country's two busiest aviation hubs [1].
AENA will manage passenger capacity on a per-terminal basis [3]. This strategy is designed to maximize the use of available terminal space as air traffic continues to rise [2]. The constraints focus specifically on peak-hour demand to ensure that infrastructure can keep pace with the volume of arrivals and departures [2].
Airline operations will be affected by these new restrictions, though existing rights remain protected. "Airlines will retain their historical slot rights in Spain, but any new requests during peak hours will be redirected to off-peak time slots," Aviacionline said [3].
The decision follows a period of sustained growth in international and domestic travel. AENA intends to use these limits to ensure long-term capacity, and address the specific demands of modern infrastructure [1]. The focus on the summer 2027 season [1] allows airlines and airport staff to adjust schedules and staffing levels before the limits take effect.
Officials said the measures are necessary to balance the economic benefits of tourism with the physical limitations of the airport terminals [1]. The transition to per-terminal capacity management represents a shift in how Spain handles its primary gateways to the world [3].

The implementation of capacity limits suggests that Spain's primary aviation hubs have reached a saturation point where physical infrastructure can no longer support unrestricted growth. By shifting new flight requests to off-peak hours, AENA is prioritizing operational stability over maximum volume, which may lead to higher ticket prices or reduced flight frequency during peak travel windows starting in 2027.
