Overnight, the city of Longston, Ontario springs up 500 km northwest of Toronto. The city has a population of 1.5 million.
AC schedules almost hourly A319 service between Longston and Toronto and it is anticipated that almost every seat will be filled most of the day. Half of the passengers will be travelling to Toronto, the other half travelling onwards/
