Finnair will cancel all flights to mainland China until April 30 in response to the coronavirus outbreak.
The flag carrier flies to Guangzhou, Nanjing, Beijing Capital, Beijing Daxing, Shanghai and Xi’an.
It has also announced numerous reductions to other services.
Daily flights to Seoul will be suspended from March 9 to April 16.
Throughout April it will fly to Hong Kong once daily rather than twice daily.
It will also reduce its Osaka route from 12 to 10 weekly frequencies from March 29 to October 24.
The launch of a new route to Busan will be postponed from March 31, 2020 to July 1, 2020.
Meanwhile, flights between Helsinki and Milan will be suspended between March 9 and April 7, following an updated travel advisory from the Finnish Foreign Ministry on travel to the city.
The airline said further scheduling changes may follow.
It said it would communicate with customers on affected flights, who will be able to claim a full refund or postpone travel.
Customers with Finnair flights booked in March will be able to change their travel date to the same destination until the end of June 2020.
The airline also said it would begin negotiations on temporary layoffs affecting its entire Finland-based staff, as well as those outside the country.
This may see staff made to take unpaid leave for 14 to 30 days.
Finnair has long focused on connectivity to Asia. The airline’s new CEO, Topi Manner, recently told Business Traveller its strategy this year would centre on increasing frequencies to Asian megacities.
The airline has now withdrawn its capacity guidance of approximately 4 per cent growth for 2020 and has issued a profit warning.
