Eyes to the skies, You have also encountered such pax? You know if I start searching for their bags and they show up before they are found in the belly afterall, I still refuse to take them with me, since they caused the delay in the first place. It helps offcourse if the groundstaff removes the ''jet-way'' first, something the groundstaff are willing to do always!
I had pretty good results with above treatment. In fact it is also company policy not to wait.
