I read someone say on another thread that the cabin must be checked for security reasons if a passenger leaves the aircraft following a diversion before you can depart again for your original destination. Makes perfect sense. But I wanted to ask:
When you divert and park up at the stand, do you have to disembark all the passengers, carry out the security search, then re-embark them? Or can you do it with them on the plane to minimise disruption / the delay?
