Fast-tracking saves time and hassle and makes the passage through an otherwise busy or difficult airport both fast and easy. A successful Fast-tracked airport service is one where you did not have to queue in line, and/or the time it took to pass through the airport was reduced. Fast-tracking is achieved differently in each airport. In Hong Kong the agents will request use of special fast track lines at Immigration and Border Control, but this cannot be guaranteed. In fact the special lines may take longer than the regular channels as they have to support immigration for elderly assengers, for disabled passengers and for unaccompanies minors or families with children. Having this in mind the agent will choose the best option for you on the day.
