I visit the nordics regularly and have noticed the number of question I’m asked at the immigration desk has gone up from a maximum of one to half a dozen or so recently.

I did an ex-EU from ARN (SAS Gold trip!) in February and don’t recall the specific questions I was asked, but also don’t recall being worried about not getting into the country! Perhaps the way a question was answered, or the way the answer was perceived, triggered the immigration officer. I tend to just say I’m there as a tourist rather than saying I’m there for a tier point run or just for the sake of flying.
