It now says the 13th according to the Wallenius website. :-( That really sucks. Strong head wind or something?
How I got this information:
From the main page, go to "Cargo Tracking", then click on "Auto Cargo". Enter the vin number of your car. On the resulting page, there will be a "Voyage" field that says "EA543-MIG". That is a link to the actual voyage tracking. Click on it. The estimated arrival dates (and departures) are all listed.
