I should have asked. I was just there last week.
My attention was always caught by the number of small
planes flying around - it surprised me, actually.
I was on the west coast, as well as Copenhagen, and
I'll bet I saw 2-4 a day during the 4 total days I spent there.

One was right over downtown Copenhagen at about - maybe 2500 - 3000 feet.

I wish I would have had the chance to take a flight.
Maybe next time.

I'd be interested in the info, too.
