@Friendly Dispatcher: Seconded!
@AirResearcher: That is the plan always, tell the pax, wait until your row is called. Some do it by colour of the boarding cards, some by rows, some by classes. The problem as always: the pax
We used to do it even when boarding with busses: Passengers from row 15 (or else) please use rear airstairs.
Usually passengers leave their brains at home.
Ever been at a gate where you do several calls: ONLY rows 30 to 35 and watch how many passengers with seats in other rows want to pass the gate.
