The International Energy Agency (IEA) warns that Europe has only about six weeks of aviation fuel reserves remaining due to the ongoing blockade of the Strait of Hormuz. Executive Director Fatih Birol described the situation as the largest energy crisis ever faced, noting that flight cancellations may occur soon if supply chains remain disrupted. The European Commission is currently gathering data on refinery capacity to develop an emergency response plan.

The European Commission stated that initial constraints in the new European Entry/Exit System are normal, but emphasized that resolving these issues at airports is the responsibility of individual member states. The system, which came into force last Friday, caused significant delays at Portuguese airports over the weekend.

The Public Security Police (Polícia de Segurança Pública or PSP) suspended biometric data collection at departures in Lisbon, Porto, and Faro airports on Saturday morning to prevent passengers from missing flights due to excessive wait times. The system, part of the new European Entry/Exit System, resumed operations by the early afternoon. Officials confirmed that biometric collection remains active for all arrivals.

Update: Airport biometric data collection resumes after temporary suspension

PSP spokesperson Sérgio Soares confirmed that biometric data collection is now operating at full capacity for both departures and arrivals. The suspension was a contingency measure implemented after the new border control system caused significant queues, leading some passengers to miss their flights.

Snowfall has led to the closure of several road sections in the central massif of the Serra da Estrela mountain range. The National Civil Protection Authority (Autoridade Nacional de Emergência e Proteção Civil) confirmed that segments of the National Road (Estrada Nacional or EN) 339, including the route to the Torre summit, were closed to traffic late Tuesday.

The government will extend the current ground handling licenses held by Menzies at Lisbon, Porto, and Faro airports. This decision follows an injunction filed by a competing company, with officials aiming to prevent potential operational issues during the busy summer season.

Infrastructure limitations at Lisbon airport (Aeroporto de Lisboa) have resulted in 12% of requested flight slots for the summer season going unfulfilled. The National Air Navigation (Navegação Aérea de Portugal or NAV) warned that these capacity constraints are penalizing the tourism sector. Travelers should note that the lack of slots may limit flight options and keep ticket prices high during the peak season.

Operations at Madeira International Airport were reported as returning to normal after two days of disruptions that cancelled more than 70 flights. ANA - Aeroportos de Portugal reported that all scheduled arrivals between 08:00 and 10:00 landed and only one departure was cancelled, though it kept alerts for weather forecasts. Travellers should still check their airline status and expect last‑minute schedule changes while conditions stabilise. Those flying to or from Madeira should reconfirm flights with carriers and monitor ANA notices.

Traffic remains restricted or suspended on several railway lines after recent bad weather, with CP reporting problems on the Northern, Beira Baixa, Beira Alta, Douro, Oeste and Coimbra Urban lines. Some sections are operating with reduced frequency or replacement buses while inspections and repairs continue. Expect delays and altered timetables on affected routes; check Comboios de Portugal's live updates before travelling and allow extra time for connections. Those travelling by train in the coming days should confirm services and ticket-change options.

Update: Correio da Manhã confirms continued constraints

Correio da Manhã reports the same lines remain affected and that inspections and repair work are ongoing; the outlet warns of continued delays and recommends checking operator updates for the named routes.
