Airport operator AENA confirmed on Monday that it will publish capacity limits by terminal and traffic type—rather than only by runway—starting in the 2027 summer season at Spain’s two busiest gateways. The move is designed to ease terminal congestion during morning and evening peaks without curbing overall traffic growth. Under the new system, airlines wishing to add flights at saturated hours will be encouraged to shift operations to off-peak windows or to less-busy terminals.

Whether your team is rerouting trips to shoulder hours or simply keeping tabs on biometric rollouts, VisaHQ can streamline the paperwork behind each journey. Its Spain-dedicated portal consolidates visa, passport and EES-readiness requirements in real time, providing alerts and concierge support so travelers clear the formalities as smoothly as the new slot rules intend.
Historical slot rights will remain intact, avoiding the politically sensitive reallocation battles seen at other congested European hubs. AENA stressed that the plan is a stop-gap until its €10 billion DORA 3 investment package— which includes major terminal expansions in Madrid and Barcelona—comes online between 2027 and 2031. For corporate mobility managers, the announcement is both a warning and an opportunity. Carriers may re-time departures, forcing itinerary adjustments and tighter connection buffers, but the redistribution could also unlock shoulder-hour capacity that is cheaper and less delay-prone. Travel-management companies recommend mapping critical routes now and negotiating flexibility clauses with airlines ahead of the slot-allocation cycle that opens this autumn. The decision comes against a backdrop of robust demand: Madrid handled six million passengers in May (+4.8 % year-on-year) while Barcelona processed 5.5 million (+6.4 %). Seat-capacity analytics show summer 2026 departures up 7 % and 5.5 % respectively, underscoring the urgency of demand-management tools. In parallel, business lobby groups are pressing AENA to clarify how the terminal quotas will interact with the EU’s new biometric Entry/Exit System (EES), due to be fully operational next year, lest passport-control bottlenecks offset any gains from slot smoothing.
