Some comments here are interesting, as it’s in the interest of safety.
It seems to be a big anti UK and USA sentiment here on the security issues. In some cases I can understand the frustration of this.
However we have the Russian kid in the cockpit crash and we have the missing MH370.
It’s important here not mixing up airline crew and ordinary passengers.
SOPs from ALL companies I have knowledge of would not allow any passengers without prior approval of management in the cockpit.
I was just curious in this, apparently it’s. It just UK and USA where accidents happen.
Btw I managed to bring several youghurts with me trough UK security without an issue. I also agree that some of the rules can seem draconian, however I am not convinced letting a passenger into the flight deck is one of them, as history has shown us.
