Key points

Strike window October 17-20 across major Portuguese airports
Minimum services require island links and some international flights
Expect slower check-in, baggage delays, and day-of schedule changes
Arrive earlier, go carry-on, and document service failures
Escalate through airline, then ANAC, for EU261 remedies

Impact

Airports: Lisbon, Porto, Faro, Madeira, and Azores stations face slower handling and potential day-of delays.
Flights: All mainland-island and inter-island links must run, with a slice of international flights protected.
Travelers: Arrive early, use carry-on only if possible, and monitor your flight's gate and belt changes.
Outlook: Additional October weekend actions are noticed; disruption risk persists beyond the formal windows.

Ground-handling staff represented by SIMA are striking again, placing pressure on airport operations in Lisbon Humberto Delgado Airport (LIS), Porto Francisco Sá Carneiro Airport (OPO), Faro Airport (FAO), Madeira's Cristiano Ronaldo International Airport (FNC), and the Azores, from Friday, October 17, through Monday, October 20. Portugal's arbitration tribunal has imposed minimum-service rules for the October weekends, which guarantee lifeline domestic links and a portion of international services. Travelers should plan for slower check-in and baggage delivery, plus day-of schedule changes, even where flights still operate. The practical move is to arrive earlier than usual, travel with carry-on only if possible, and know how to escalate when promised minimum services are not delivered.

Portugal airport strikes, minimum services, and who is affected

Portugal's arbitration tribunal set specific minimum services for SIMA's October actions affecting Menzies, the handling company that serves many airlines nationwide. For the October weekends, authorities require 100 percent of flights between the mainland and the islands, all inter-island services, protection for certain TAP aircraft positioning into Lisbon, and at least a portion of international flights, set at 20 percent for this month's notices. That framework explains why schedules may exist on paper while passenger handling still moves slowly on strike days, especially at peak times.

Latest developments

For October, the tribunal confirmed minimum services covering three strike windows, including October 17-19. U.S. traveler guidance has highlighted the surrounding Friday to Monday periods because disruption often spills into the first morning after a declared stoppage as airlines reposition crews, aircraft, and bags. Expect the greatest friction at check-in, baggage drop, and baggage reclaim.

Analysis

What to do now. Arrive at least three hours before an intra-Europe departure and four hours for long-haul during October strike weekends. Use carry-on only if you can, since baggage systems rely on the very workers striking, and mishandled luggage claims can take days to clear after a wave of disruptions. If you must check a bag, put your name and contact details inside and outside, photograph your bag and claim tag, and keep medication and valuables with you.

Know your rights. Under EU Regulation 261, if your flight is canceled or significantly delayed, the operating carrier owes care and rerouting, and in some cases compensation, although compensation often does not apply when disruption stems from third-party strikes. Care and rerouting still apply, so insist on meals, hotels when necessary, and the earliest reasonable rebooking.

How to escalate if minimum services are missed. If a guaranteed category is not served, ask gate staff to document the reason in writing, request rerouting on the earliest available flight on any carrier, and keep receipts for out-of-pocket costs. If the airline refuses required care or rerouting, file a complaint with Portugal's civil aviation regulator, ANAC, and attach proof of denial and expenses. Airports in Portugal also publish passenger-rights summaries that mirror EU rules, which you can cite when negotiating at the desk.

Final thoughts

The Portugal airport strikes are designed to pressure ground operations without stopping all flying, which is why minimum services matter. For October 17-20, plan extra time, travel light, and be prepared to assert your EU rights if your flight is canceled or significantly delayed. The primary keyword, Portugal airport strikes, will remain relevant through the remaining October weekends.
