No, it depends on what origin is deemed “clean” that day by security. If contact gate then transit pax are let out straight into the departures area rather than going up the escalator with DOH terminating pax. If bus gate then the bus stops first at a bus departure gate and an agent comes on board the bus to announce for transit pax only to get off; DOH terminating pax stay on and are bussed to the usual arrivals bus gate.
