The focus is on routes/flights with high proportion of passengers with roots from, or travel history in, SW Asia (Turkey/Middle East) or Africa. Don't expect lots of this on my OSL/ARN to CPH flights.
Coming into CPH from MUC or FRA or ZRH on early morning flights make it very unlikely to be hit by this thing. Also, if coming in on weekends, you can guess what the odds are relative to a slow time during the weekdays.

Coming in from VIE works better when the flight arrives at a time when they are busy focusing on IST-originating flights. Also, coming in on charter tour flights from sun resort areas seems to drop the odds of being hit by this at this time of the year.

The TSA does on-arrival gate checks from time to time, but CBP/ICE (distrinct from TSA) very rarely does searches on-arrival for flights that aren't from a foreign travel zone. In the EU, expect more immigration/customs on arrival even for intra-Schengen flights than the TSA "reverse screening" nonsense.
The days of these searches on intra-Schengen arrival at CPH/ARN/OSL being largely limited to flights from AMS is gone.
