STOCKHOLM, Sweden (AP) _ Scandinavian Airlines System canceled 70 flights Tuesday, stranding about 5,200 passengers, because of a wildcat strike by SAS flight attendants and ground staff.

SAS spokeswoman Pamela Collin, said plans were being made to book international passengers on other airlines and move Scandinavian travelers by train or bus.

The airline, owned by governments and private investors in Denmark, Norway and Sweden, canceled 45 foreign and 25 domestic flights. Collin said the airline lost at least $2 million for the day.

The strike was expected to continue Wednesday.

Strikers were angered by plans by SAS to cut its staff by 1,500 to make room for employees of Linjeflyg, a domestic Swedish carrier bought by SAS. About 600 positions are to be cut from SAS and 900 from Linjeflyg, but striking employees say they want almost all of the cuts to come from Linjeflyg.

Union leaders arrived at Stockholm's Arlanda International Airport to ask the employees to end the strike, which violates an agreement with the airline, but were booed.

Collin said the wildcatters, who sat in the sun, in uniform, outside the airport terminal, lost pay for the day and had their passes for free travel canceled. She said the company would have to go to court to take further action if the strike did not end soon.

Danish flight attendants held a wildcat strike lass Thursday and Friday. On Tuesday, Danish SAS employees stopped work for one hour in sympathy with the Swedish strikers, causing four canceled flights from Copenhagen.

SAS has said some of the extra employees would be offered other jobs, some would be given incentives to leave, and firing would be a last resort.
