British tourists visiting a popular city-break hotspot has been issued an urgent travel warning as twin strikes are set to hit the country in next three days. Finnish airport is likely to face more strikes again this week, marking the tenth walkout in just 45 days (most for any country).
Approximately 143 flights will be cancelled on Tuesday, 17 June, due to a four-hour industrial action by the Finnish Aviation Union (IAU) at Helsinki Airport. The strike affects key ground operations throughout the day, impacting around 6,500 passengers. Finnair will rebook affected customers or offer refunds. Customers are advised to check in early, pack essentials in carry-on bags, and expect longer customer service wait times.
A similar strike is planned for June 19, and Finnair will confirm related cancellations on June 17.
According to the experts, the latest wave of strike action will impact 54-64 flights (flights originating from the UK), affecting up to 11,520 UK passengers.
Key routes which will be impacted include London, Manchester, and Edinburgh to Helsinki, which have 14 direct flights.
Other routes (with 1 or 2 stops) include Birmingham, Bristol, Belfast, Nottingham, Southampton, and Leeds to Helsinki via Amsterdam, Stockholm, Copenhagen, and Latvia (40-50 flights), the travel experts have warned.
Anton Radchenko, Aviation expert & Founder of AirAdvisor said: “We have reached a point where UK travellers no longer need to be warned about Finnish aviation strikes, they expect them, which is a serious reputational crisis. For many Brits, Finland is no longer seen as a safe or reliable part of the travel map.
“These aren’t isolated events anymore; they are stacking disruptions. Passengers are missing connections, losing confidence, and taking their business elsewhere. The deeper issue here is one of trust. Travellers don’t just book tickets, they plan around reliability.
“And what we’re seeing is a full-scale erosion of that trust. When people start rebooking through Stockholm or rerouting Asia trips via Frankfurt instead of Helsinki, the damage isn’t temporary; it becomes structural. Airlines eventually follow those behaviours, shifting routes and investing in more stable hubs.”
