National air carrier Finnair said on Sunday that it will not board passengers with symptoms that suggest they have Covid-19, the disease caused by novel coronavirus.
It said that passengers boarding flights to return to Finland will also be checked to ensure that they can withstand the physical stress of air travel.
Passengers who begin to display symptoms during the flight will be isolated and the flight crew will alert local authorities, the carrier said.
At the same time, Finnair called on returning passengers to retreat to conditions similar to self-quarantine for two weeks once they arrive in Finland.
The announcement came as the airline revealed plans to lay on extra flights to bring Finnish citizens and residents home from holiday locations in Spain and Turkey.
"It is very important that people understand their own responsibilities and do not board flights while they are sick," Finnair communications director Päivyt Tallqvist.
