There's another promo on upgrades in the latest edition of the Blue Wings magazine under the heading 'Best from partners'
(page 83):
Northern Europe upgrades 5000 points
Europe upgrades 7000 points.
Sales period runs from 3-23 Jan.
Lucky loser me. I have LHR, DXB, AGP widebodies upgraded coming but I cannot go cancel and reupgrade those to save points since the tool says no upgrade space available.
