The bags are still screened to the same level regardless of what tag is on the handle though, so the risk is minimal, surely?
I went through AMS last week EDI-AMS-KBP. On the way out I had no extra screening between getting off the EDI flight and boarding my KBP flight. On the way back I was screened between the KBP and EDI flights, presumably because KBP is non EU, even though they adhere to the same standards as the EU.
