Great tips. Except, when flying in the US you have to leave your toiletries out because they are inspected separately when you go through TSA security. (I always try to include something terribly embarrassing for them to find at as I figure it's probably a pretty boring job)
I always bring a backpack on the plane with the toiletries and a change of clothes in case my baggage ends up somewhere else, as it has on several occasions.
Have a nice trip, Indian Summer. The days are getting long in Norway about now, I imagine.
