Only got back to sweden on friday (and therefore missed the triple miles op for my return leg by one day!!!!!!!!!!!!!!!!!!!!)
Interesting my return leg has already posted, I tired the online claim with the ticketnumber i got from virtually there, but they system tells me it has a problem with the ticket number (maybe similar to the problem you have where it see miles for that leg are already posted?)
So I will be putting the details i have in the mail with their manual form on monday and see what happens.
I have a vague hope they will process it during december, and the system will screw up and apply the triple miles offer for me
