There seems to have been some H&S tightening on the ramp which means inbound pax are not deplaned with a departure manoeuvring on the gate to the left. Fair enough, but now it seems as soon as that aircraft alongside has doors closed, nobody can move from a recent arrival until it's gone. Last time through it was getting on for 10 minutes after shutdown before pax were allowed out, the beacons never started on the adjacent aircraft for quite some time during all this (with pax of course all standing in the aisle). As LCY has always had a hissy fit with any operators taking more than 30 minutes on stand at peak times, the ground arrangements can hopefully be reviewed. Again.
