While TransportGroup, the umbrella association representing those companies, claims that the strike will not affect flights considerably -- at least at the outset, the union says it will have a big impact on passengers.
Elisabeth Manzi, public relations officer for SAS, told TT that passengers with travel tickets should show up to the airport as planned.
"In concrete terms, this means that we won't be able to carry out maintenance work on our planes. But come tomorrow, our ambition is to fly as much as we can," she said.
TT reports that another strike may follow next week, also from Thursday until Saturday.
