According to preliminary data from the National Institute of Statistics (INE), this performance reinforces the structural robustness of the national tourism and services sectors. In December alone, Portuguese airports recorded 4.9 million passengers, an increase of 4.6% compared to the same period in the previous year, underscoring the country's attractiveness even during the so-called low season.

The daily average of passengers disembarking in December was 82,100, a value significantly higher than the 78,000 recorded in the previous year. This continued growth — following a 4.3% increase in 2024 — is seen by experts and policymakers as a sign of economic stability and a fundamental pillar of tourism revenue, foreign direct investment, and international trade.

The aviation sector thus remains a critical driver in positioning Portugal as a competitive hub for global business and technological services.

Regarding the main markets, the ranking of the five largest countries of origin and destination remained unchanged in 2025. The United Kingdom retained its leadership as Portugal's main aviation partner, with growth exceeding 2% in both arrivals and departures, reflecting deep ties in tourism and real estate. France maintained second place, despite slight declines, followed by Spain, Germany, and Italy.

This diversified demand base is considered essential for the sector's resilience, reducing dependence on a single market and ensuring positive prospects for 2026, as airport infrastructure expansion and modernisation projects progress.
