A wild idea:

SVG-IAH is moved to CPH-IAH with a wide body (SVG-IAH is clearly not a success - and IAH could serve as access point to the latin american market)

OSL-MIA (it seem like SAS has committed themselves to a IC routes from OSL)

ARN-SFO (CPH-SFO seems to be very successfull - and if I remember the SAS quotes right, they stated their most successfull IC start up in a long time)

The 737 all biz is moved to SK901/902 all year service (believe it is leased on a 3 year contract.

Could also speculate that they have ARN-HKG on the radar screen, to do something, either on timing or routing. Bookings seems not to be as expected (with all the summer and EB deals lately). The last two IC route launches from ARN did not sucdeed (PEK and BKK).

Dont believe in BOS (to few onward connection options from BOS. DEL has been tried a couple of times - miserable failures both times.
