Something for all you wondering about the reason for SAS to
re-registrant all new aircrafts all the time.
I picked up this from www.sasflightops.com
"The most frequently asked question we get from you visitors is:
Q:Why do SAS re-register the fleet?
We have now got the correct answer from our information department.
A: The Swedish law do not allow ???Sale lease-back??? Of an aircraft if not the aircraft physically change operator as well. Because of that SAS has been forced to re-register the major part of the fleet from Swedish(SE-) registration to Norwegian(LN-) or Danish(OY-).
Finally an answer to all these questions."
