Finnair pilots’ strike forces cancellation of 300 flights and rerouting of 33,000 passengers

Finnair pilots’ strike forces cancellation of 300 flights and rerouting of 33,000 passengers
Finnair confirmed in a press release overnight that it will be unable to operate some 300 flights on 9 and 13 December as members of the Finnish Air Line Pilots’ Association (SLL) stage a two-day strike over stalled collective-bargaining talks. The announcement was posted just after midnight on 11 December, giving business travellers only four days to rearrange itineraries.

According to the carrier, about 33,000 customers will be affected. Finnair says it has already begun automatically rebooking passengers onto alternative flights, prioritising long-haul routes and Christmas-season traffic, but warns that “hundreds” of travellers may still face significant delays or route changes. Corporate travel managers have been urged to ensure employee mobile numbers and emails are up to date in Finnair’s booking profiles so that automated re-routing messages are received.

The strike is part of a broader dispute that began when the pilots’ collective agreement expired on 30 September. Negotiations have dragged on for ten rounds without a breakthrough on pay progression, roster stability and stand-by rules. Finnair management argues that wage increases above the national labour-market framework would jeopardise the airline’s fragile post-pandemic finances, while pilots counter that current fatigue-mitigation measures are inadequate for the carrier’s ultra-long-haul schedules.

From a global-mobility perspective, the walk-out underscores the importance of contingency planning for travellers transiting through Helsinki, a popular hub for Asia-Europe connections. Companies with posted workers en route to Finland—or using Finnair as an onward connector—should review duty-of-care obligations, explore alternative routings via SAS, Lufthansa or Middle-East carriers, and verify Schengen visa validity if re-routed through a different EU entry point.

For travellers who suddenly need to reroute through other Schengen hubs, VisaHQ’s Finland desk can expedite visa procurement and provide real-time guidance on entry requirements across the region. Its digital application tracker and dedicated support team (https://www.visahq.com/finland/) help corporate and leisure passengers navigate last-minute changes when industrial action disrupts planned itineraries.

If no settlement is reached, the pilots’ union has signalled it could announce further industrial action during the peak New-Year travel window. Employers should therefore monitor updates closely and build extra flexibility into January assignment start dates. The Ministry of Transport has already convened a mediation task-force, but both sides acknowledge time is running short.
