@matigo Absolutely. Cabin Crew as a part of their post-landing checks, security check of entire aircraft cabin should’ve been done. Additionally, even ground staff should’ve checked the aircraft before it was being towed for parking in a remote bay. Not sure though whether there are systems at airports to verify whether all arriving passengers passed through the immigration, unless they check & maintain records in comparison to API 1 2
