I have heard about some Schengen pax - entires flights being redirected to immigrations booth at LYS., NTE and even ORY...
The flights were all originated from PRG.
For CDG it seems to be a 2F2 issue, if you take an OK/QS flight arriving in 2D, space is so limited in this terminal that checks are not even carried out. So 2D is the loophole to France.

If it is only about showing to le bon peuple that borders are « properly secured » I really think than Central / Eastern Europeans nations I live in are definetly doing more for immigration than France is really trying to show, without these ID check for arriving Schengen flights. Wondering why they are controlling pax coming from places where EU immigration policies are more strictly enforced compared to F, useless, especially if it takes place only during regular civils servants working times, so at 5PM it is time to go home.
So are we in Schengen or half-Schengen at the end?

As there is no SP lane, did someone try a DYKWIA to the airport agents managing this ID checks lane to make a way to the front?
