The point of my post was to help others avoid a problem.
Let's keep it simple.
ALL passengers entering Oslo with a non-EU passport, are potentially going to face a 2 to 3 hour long line, standing with no place to sit, and no where else to go except through the passport control.
For those that the details are so important, here are a few.
I experimented with an airline I didn't know. I purchased a premium large seat on Norse Air to go to Copenhagen, including lots of baggage allowance, lots of food, movies, etc. I was to arrive 2 days before the cruise departure from Copenhagen. I had spent a lot of time in Copenhagen in the past, so I was arriving early to revist a few of my favorite places. In the past I had had no problems on short flights with Norwegian Air, so I was comfortable with the connection.
It does not matter how much you paid for your ticket. - You will still wait!
It does not matter which airport outside the EU you came from.
It does not matter which airport you are connecting to.
I rarely post comments like this. The purpose of this is to make people aware of a potential problem if they transit via Oslo.
When I realized the length of the line I thought that a serious problem might have occured as the line snaked back and forth through different corridors, and curiosity led me to inquire of the personnel. It seemed that there might have been something going on, like a strike, power failure etc. More planes landed after mine and many of the people seemed bewildered by the line they were told to get in. But the casual replies that "No, this is the busy time of day, it's like this most days" really upset me, and I can assure you most of the people in that line were equally surprised. I felt compassion for many of the elderly as they moved a few feet at a time for hours.
HOWEVER, none of this has anything to do with the preposterous laid back attitude of everyone at the airport that such a wait is just a normal occurance. If you can't fix the wait, at least provide benches and chairs along the way. This whole situation is far removed from the usual competence and ingenuity of the scandinavians.
