Ministério das Infraestruturas Opens Technical Validation of ANA's €233 Million Humberto Delgado Expansion Plan — South Pier, 10 New Boarding Bridges and 45 Movements-per-Hour Target Head to APA

The Ministério das Infraestruturas opened on 10 June the technical-validation phase on ANA Aeroportos de Portugal's €233 million expansion plan for the Aeroporto Humberto Delgado (Humberto Delgado Airport, Lisbon), the document the Vinci Airports-controlled concessionaire filed in August 2025 to lift the airport's declared capacity to 45 movements per hour. The review involves Anac (the civil-aviation regulator), NAV Portugal (air-traffic control), Aeronautical authorities, the Agência Portuguesa do Ambiente (APA — Portuguese Environment Agency) and the Direção-Geral do Território, with the explicit objective of producing a binding technical opinion on the plan by end-September 2026 so that ANA can move to the Environmental Impact Study (EIA) phase before the end of the calendar year.

The plan's physical centrepiece is a new South Pier extension to Terminal 1, adding 33,000 square metres of pier space designed to a higher environmental-performance standard than the existing 1990s-vintage terminal, ten new boarding bridges, an extended aircraft parking apron, a reformulated connection between the Central Pier and the new South Pier, and a complete reformulation of the current South Busgate. ANA's submission frames the package as the minimum capacity unlock needed to bridge the gap between today's 38 movements-per-hour declared capacity and the 45-movements-per-hour target that the Lisbon airport-system planning bands have agreed sits at the operational ceiling of the existing runway geometry, pending the eventual handover of the long-haul and overflow demand to the new Aeroporto Luís de Camões in Alcochete.

The €233 million headline figure breaks down across phased works that ANA proposes to execute on a 36-month construction calendar. Roughly €120 million covers the South Pier civil works themselves; €45 million the apron extension and the boarding-bridge package; €28 million the Central Pier reformulation and the connection works; €22 million the South Busgate rebuild; and €18 million the auxiliary systems — baggage handling, hold-baggage screening, IT and electrical-distribution upgrades. The financing structure relies on ANA's own balance sheet inside the Vinci Airports group and the regulatory tariff-pass-through mechanism that the Anac operates under the airport-concession regulatory framework. The Ministério das Infraestruturas, in line with the 2023 strategic-orientation document, will not commit direct State funding to the works.

The capacity-unlock target — 45 movements per hour, compared with the current 38 — is the binding metric for the airline community and the wider tourism sector. At 38 movements per hour the Lisbon airport tops out at roughly 33-34 million passengers a year, and the 2025 traffic tape hit 35.6 million passengers; the system is already operating at and occasionally above its declared operational capacity, with the AirHelp 2026 ranking we covered earlier this week sitting at 274th of 279 audited airports globally on delay, cancellation and passenger-experience metrics. A 45-movements-per-hour ceiling would lift the throughput envelope to roughly 41-42 million passengers annualised, which the Vinci Airports planning team argues bridges the operational gap until the Luís de Camões new airport reaches its declared operational date around 2034-2035.

The environmental-review track is the longest pole in the calendar. ANA's submission will need to clear an APA-led Estudo de Impacte Ambiental that covers noise contours over the Loures, Odivelas and Olivais residential perimeters, air-quality modelling, the surface-water and ground-water effects of the apron extension, and the cumulative-impact assessment with the broader airport-system planning. The APA review window is statutorily 90 days but historically runs 6-9 months on projects of this scale; the Government's stated objective is to have a Declaração de Impacte Ambiental (DIA — Environmental Impact Declaration) in hand by Q2 2027, which would allow ANA to start the South Pier works in the second half of 2027 and target the 45-movements-per-hour operational date around late 2030.

The political surround of the expansion plan is unusually balanced. PSD, CDS and Iniciativa Liberal back the expansion as the necessary near-term bridge to the new airport; PS and Livre support it conditionally on the noise-mitigation measures matching the residents' associations' demands; Bloco de Esquerda and PAN oppose it on environmental grounds, arguing that the capacity unlock will lock Portuguese aviation into a higher-emissions trajectory through the late 2030s. The Câmara Municipal de Lisboa under Carlos Moedas has signalled support for the expansion subject to the night-flight curfew agreed in the 2023 concession-renewal framework being preserved — the curfew runs from 00:00 to 06:00 and the residents' associations want it extended to 23:00-07:00. The 17 June Conselho Estratégico do Aeroporto meeting will set the framework for the formal Anac and APA review windows.

What This Means for Travellers, Airlines and Greater Lisbon Residents

• Operational capacity stays at 38 movements per hour through at least 2030. The expansion plan, even on the optimistic 2030 operational target, leaves the next four-plus summer cycles running at the current capacity. Expect continued peak-hour delay-cancellation pressure of the kind the AirHelp ranking flagged, with peak-season volatility concentrated on the early-morning and late-evening windows.
• Airline route planning will be conservative through the expansion window. TAP, Ryanair, EasyJet, Lufthansa and Air France all flagged in their 2026 capacity-planning rounds that Lisbon slot allocation is the binding constraint on Iberia growth. Slot trading inside the IATA system will continue to dominate, and new-entrant routes face a multi-year wait list.
• Loures, Odivelas and Olivais residents will see noise contours expand modestly even at the current capacity. The 45-movements-per-hour target adds incremental noise at peak hours; the APA noise-mitigation envelope inside the EIA will be the operational lever residents' associations push hardest on. The night-flight curfew is the single biggest issue at the 17 June Conselho Estratégico meeting.
• The Luís de Camões new airport remains the structural answer. The Humberto Delgado expansion is a bridging plan, not a replacement plan. The Luís de Camões operational date — currently pencilled at late 2034 to early 2035 — is the single most important piece of Lisbon aviation policy and remains the bottleneck whose schedule will determine whether the city's air-transport system catches up with demand before the late 2030s.

ANA's expansion plan documentation is available through the Ministério das Infraestruturas portal at portugal.gov.pt; Anac's regulatory updates are at anac.pt; and APA's EIA pipeline is at apambiente.pt. We will return to the framework when the technical-validation opinion is published in late September.
