Sometimes you get noticed more than others.
I think I have only ever flown without my Kilt once. (And I have flown A LOT!)
Usually the guys letting me into the country are polite and interested and there is always one woman who just has to do a kilt check while my arms are full of luggage.
The only bad experience I have had was when they asked me to remove my Kilt (Not in a private room) so they could put it through the x-ray machine. I did it because I was more interested in getting into the country to see my wife than causing a fuss.

Glad you enjoyed your trip!
