On several long hauls airlines make a stop, mostly to refuel, sometimes for commercial reasons. Mostly these stops don't take more then 1hr 40mins.
I wonder whether ongoing pax are always allowed to deboard the plane? Is there a given time interval when, once exceeded, the airline is to leave the pax of the plane??
examples : SIN-ZRH-BRU, JFK-ANC-TPE, BKK-NRT-LAX
Tnx for helping me out.
