The country's airport operations company Finavia said the first day of the security personnel strike has not so far caused significant delays at Helsinki Airport.
Finavia's operations manager Jani Ceder said there was no significant congestion at Helsinki Airport Wednesday morning, the first of a three-day strike by security staff members.
Thousands of unionised security workers across the country began a three-day strike after compensation and benefits negotiations between employer and employee unions broke down last week.
The industrial action is affecting security operations not only at Finland's airports but also some railway stations, hospitals and shopping centres and stores across the country.
The strike will most affect security operations at the airport's Terminal 1.
Ceder said delays at security check queues at Terminal 2 could occur later in the afternoon on Wednesday, adding that there may significant queues at Helsinki Airport particularly between the hours of 2:00-5:00 pm.
Advisory: Arrive at least two hours in advance
In an announcement about the strike that the agency said it would continue to update , Finavia requested that departing passengers arrive to the airport in good time and that they double-check their airline for possible changes in schedules.
"Normally we ask that passengers arrive to the airport one-and-a-half to two hours [before their flight departures], but people could come a little earlier than that to ensure they get through smoothly," Ceder said.
The airport's priority security control in Terminal 1 will not be in use for the duration of the strike, but passengers are still able to use Terminal 2's priority security queue, according to Finavia.
”We will make every effort possible to minimise the impact of the strike. For example, we are working in close cooperation with authorities to ensure a high level of security at airports,” Finavia's security manager Ari Kumara said.
Finavia is not a participant of the strike, the company said in the release.
