Scandinavian airline SAS is offering travellers concerned about a possible strike by pilots the chance to reschedule flights for the April 26-29 period to another date free of charge. 

The Swedish, Danish and Norwegian pilot unions' joint SAS branch said this month they would go on strike on April 26 if there was no agreement on wages and terms by then, after an earlier round of talks broke down.

The offer concerns flights operated by SAS but not those operated by its partners as they will not be affected by the potential strike.
