Massive Disruptions Await Travelers in Lisbon and Beyond as Portugal’s Nationwide Strike Hits December 11—Expect Cancellations Across TAP and Azores Airlines

Published on November 25, 2025

Travelers heading to or from Portugal on December 11, 2025, face serious disruptions due to an ongoing general strike that will impact flights, public transport, and essential services throughout the country. This warning comes from the SNPVAC, the Portuguese National Union of Civil Aviation Flight Personnel, representing thousands of aviation workers. The strike, which is expected to affect major airports across Portugal, will lead to widespread flight cancellations and long delays. The Portuguese aviation industry is bracing for significant disturbances, and travelers should be prepared for a day of extensive disruptions.

With a large number of flights grounded and only minimum services in operation, this strike is set to impact thousands of people, particularly those traveling during the busy holiday season. Major airlines like TAP Air Portugal and Azores Airlines are advising passengers to double-check their flight status and prepare for longer wait times. The general strike will also disrupt public transport, schools, and other services, making it a tough day for residents and visitors alike.

What Does the Strike Mean for Travelers in Portugal?

The general strike on December 11 will be a challenging day for anyone planning to travel in or out of Portugal. With thousands of workers expected to participate, major flight cancellations are anticipated across the country’s airports. Only essential operations will be maintained, which means that many scheduled flights may be either delayed or canceled outright.

Both TAP Air Portugal and Azores Airlines, the largest carriers in the country, have already started notifying their passengers about potential delays and cancellations. Affected travelers are urged to check flight statuses in advance and consider rebooking their travel plans. Given the magnitude of the strike, travelers should plan for extra time to navigate through the disruptions.

What Should Travelers Do to Minimize Disruptions?

For those with plans to travel on December 11, here are several tips to navigate the expected disruptions:

1. Check Flight Status Early: Airlines are offering flexibility for affected passengers, so it’s crucial to stay updated on flight statuses via airline apps or websites.
2. Consider Rebooking Options: If your flight is canceled, airlines like TAP Air Portugal may offer rebooking or refund options. Don’t wait until the day of travel to make changes.
3. Prepare for Long Delays: Even if your flight is not canceled, the general strike may cause delays, so pack snacks and entertainment for a longer wait at the airport.
4. Monitor Public Transport Status: The general strike will not only impact flights but also public transport networks. If you’re relying on buses, metros, or trains to get to the airport, check their status to avoid further delays.
5. Consider Adjusting Travel Plans: If possible, change your travel dates to avoid the strike and the holiday rush. This is especially important for those visiting family and friends in Portugal.

Portugal’s Essential Services Affected by the General Strike

While aviation will be the most visible impact of the general strike, it will also affect public services across the country. Residents and tourists in Portugal should be prepared for major disruptions in sectors like public administration, schools, and transportation networks. Buses, trains, and metro services may run on reduced schedules, and some routes might be canceled altogether. The port systems may also experience delays, which could affect travel to and from the Azores and Madeira.

Given the scope of the strike, the Portuguese government is working to implement contingency measures to ensure the continued operation of essential services, but it will be a challenging day for everyone involved.

How Will the Strike Affect the Portuguese Diaspora?

The timing of the general strike coincides with the busy holiday season, making it especially problematic for the Portuguese diaspora. Thousands of people from around the world, particularly from North America, are expected to travel to Portugal to visit family and friends. The general strike will undoubtedly cause massive inconvenience for these travelers, many of whom may have already planned their trips well in advance. Those with flights scheduled for December 11 should review their itineraries and make adjustments if possible to avoid the worst of the disruptions.

How Are Airlines and Airports Responding to the Crisis?

Airlines like TAP Air Portugal and Azores Airlines have already begun notifying passengers of the general strike and are working to accommodate affected travelers. TAP Air Portugal has indicated that it will issue waivers for passengers scheduled to fly on December 11, allowing them to rebook their flights or receive refunds. The airline is urging passengers to check flight statuses in advance to avoid long wait times at airports.

Similarly, Azores Airlines has advised passengers to remain flexible with their travel plans and to expect longer than usual delays. As the strike is expected to be widespread, it’s best to plan for alternatives if your flight is canceled.

What Are the Contingency Plans for Travelers?

The Portuguese government has acknowledged the severity of the situation and is expected to implement contingency plans to ensure the continued operation of critical services, including airports and transportation networks. However, with thousands of workers set to take part in the general strike, it will likely be a day of significant disruptions. Travelers are encouraged to stay updated on any government advisories and airline alerts.

While some essential services may be maintained, the general strike will still severely impact regular activities. It’s crucial to plan ahead and expect the unexpected if you’re traveling to or from Portugal on December 11.

How to Cope with Travel Disruptions in Portugal

For anyone planning to travel through Portugal during the general strike, it’s essential to remain calm and flexible. The situation is expected to cause significant delays, but by staying informed and preparing for the worst, you can minimize the impact on your travel plans.

Whether you’re flying internationally or using public transport, the disruptions are expected to affect all major hubs. If you’re affected, rebooking your flight or adjusting travel dates may be the most practical solution. Portugal’s Ministry of Infrastructure is working to provide assistance and flexible solutions for travelers, but the key is to stay updated and plan for additional travel time.
