“…The passengers and crews transfers to their next flight leg and again, all the planes take off and leave the hub as simultaneously as possible. This sort of operation makes the best use of equipment, gates and crews so long as everything is working well (Rome et al, 1999). However, in case of disruptions, connections will be missed and passenger misconnection costs.…”
