Travelers heading to Portugal in early June are being urged to prepare for significant disruption as unions across the country confirm participation in a nationwide general strike on June 3.
The industrial action, organized by Portugal’s largest trade union confederation CGTP, is expected to impact flights, rail services, metro networks and other public transport systems.
The biggest concern for international visitors is likely to be air travel. Members of the National Union of Civil Aviation Flight Personnel (SNPVAC), representing cabin crew, voted overwhelmingly to join the strike, with around 79% supporting participation.
Portugal’s flag carrier TAP Air Portugal could see as many as 300 daily flights affected, while disruption may also extend to carriers including Ryanair, easyJet and local carriers due to crew and airport staffing shortages. Portuguese media reports suggest up to 500 flights in total could face delays or cancellations.
Rail is expected to join the strike
Rail services are also expected to suffer major disruption after unions representing workers at CP – Comboios de Portugal confirmed they would join the walkout. Metro systems in Lisbon and Porto, along with buses and ferries, may operate on heavily reduced schedules.
The strike centers on opposition to the government’s proposed labor reforms. Unions argue the measures would weaken worker protections, make dismissals easier and loosen outsourcing restrictions. SNPVAC described the proposals as an “unprecedented attack on established rights.”
The timing is particularly sensitive for Portugal’s tourism sector, which is already dealing with congestion linked to the gradual rollout of the EU’s Entry/Exit System (EES). Lisbon Airport has recently experienced long queues and intermittent system slowdowns as authorities adapt to the new border procedures.
Passengers are recommended to monitor airline notifications closely, allow extra airport time and consider flexible booking options where possible. While Portuguese law generally requires minimum transport services during strikes, travelers should still expect delays, overcrowding and last-minute schedule changes across the country.
