Just to set the record straight.
The Swedish pilot association, SPF (founded 1946), is party to the collective agreement with SAS. SPF is open to all swedish pilots, and is a signee of a number of agreements with most airline companies in the Swedish workplace. Every pilot in Sweden is therefore able to be a full IFALPA member.
Most ex-Linjeflyg pilots are members of SPF and have been represented on the board of SPF since the integration.
Pilotforbundet is a new organisation founded by pilots working for SAS after the integration of Linjeflyg in 1993. They have succeeded in getting collective agreements with a few startup airlines, primarily by agreeing to a lower standard of agreements.
SPF has had contacts with Pilotforbundet off and on during the years in the hope of reaching a merger of the organisations. The percieved injustices of the Linjeflyg integration have stopped any serious interest from Pilotforbundet.
The SAS pilot collective agreement is signed by three associations, one in Denmark (DPF), one in Norway (NSF) and SPF in Sweden. That agreement is valid for all pilots working in SAS regardless of affiliation.
