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. Special Fast Track handling can be requested where the passengers presence in the normal lines might cause security issues or disruption (e.g. if they are very famous and well known celebrities.) Otherwise the agent will request use of expedited lines at Immigration and Border Control, but this cannot be guaranteed. They will use their local knowledge and contacts to choose the best option for you on the day.
