Brits warned of 'significant disruption' to holiday hotspot as airport staff strike

has grounded 110 flights, impacting 8,000 customers, on a single day of a three-day .

Brits flying to Finland are facing travel chaos yet again, as the Finnish Aviation Union (IAU) has announced three fresh strikes on May 30, June 2, and June 4 at Helsinki Airport. This is Finland’s seventh aviation strike in under a month.

The industrial action is predicted to impact just shy of 30 UK flights across the three days. As the summer getaway kicks off, this latest wave of strikes will have ripple effects across Europe. The IAU, representing ground handling, baggage, catering, maintenance, and customer service staff, will strike over wage disputes with PALTA in 4-hour staggered shifts, leading to full-day disruptions.

to the IAU, the average earnings of Finnair Group employees rose by 6.4 percent between 2020 and 2023. During that same period the national average increase across all sectors was 10.4 percent.

The strikes are designed to maximise disruption, with union officials organising the walkouts at strategic times across a six-day window. The result is a wave of residual disruption: cancelled flights one day, incomplete baggage delivery the next, and last-minute rerouting throughout.

Palta, which represents employers, has argued that most employee groups were ready to accept the mediator's proposed increases, . It has said that the IAU is demanding adjustments beyond what others have asked for.

The cancelled direct flights from the UK will see nearly 5,400 passengers affected. Since Helsinki is a direct transit hub for Brits flying to Asia, the Baltics and Northern Finland. According to Air Advisor, 11,400 UK passengers will be affected.

Key UK routes likely to be impacted include London Heathrow to Helsinki, Manchester to Helsinki, and Edinburgh to Helsinki.

The IAU strikes are not the only ones impacting European aviation customers this week. The May 30 to June 4 strikes align with Italy’s May 28 aircrew/taxi strikes, creating a rare “Nordic-Mediterranean Disruption Corridor”, disrupting Helsinki, Milan, and Rome hubs. This will strain Frankfurt and Amsterdam connections, adding excessive pressure on these hubs.

Anton Radchenko, aviation expert and founder of , said: This is no longer a strike story, it’s a system failure story. Helsinki has now had more strikes in 30 days than most countries have in a year. This represents something far more serious than a few cancelled flights: they signal a system on the brink. Helsinki Airport, once considered one of the smoothest hubs in Europe, is now suffering from chronic unpredictability. For UK passengers, this isn’t just about Finland, it’s about how a local dispute can derail an entire travel experience across Europe.

"The most worrying aspect is the deliberate spread of these strikes. By placing them days apart, IAU is stretching airline operations beyond recovery: think of aircraft out of position, bags not making it to destinations, and crew timing out. It matters because this kind of disruption doesn’t stay in Finland; it ripples across hubs like London Heathrow, Frankfurt, and Amsterdam, making it even more chaotic."

Affected passengers should check the airline’s website and mobile app for alternative flight options and manage their bookings accordingly. Finnair has told impacted customers that they will be supported with rebooking options to minimize inconvenience.

Finnair has been contacted for comment.
