Pierre Elliott Trudeau International Airport (PET), also known as Montréal Trudeau Airport, is about 21km (13mi) west of downtown and is the centre of domestic, US and overseas flights. PET Airport (coded as YUL) has good connections to the city by either car, bus or metro (subway). The Québécois Bus Company runs Aérobus shuttles from PET Airport to downtown. At Station Aérobus, a smaller shuttle will pick you up and drop you anywhere in central downtown, free of charge. Driving to downtown Montreal from PET Airport will take roughly 20 or 30 minutes, although rush hour can extend your travelling time.
Montreal has a very extensive and extremely practical subway-bus network. The western sectors of the city are reachable by suburban trains from the Bonaventure and Vendéme stations. Although quite heavy, automobile traffic flows reasonably well. Try not to drive in Old Montreal, where the streets are narrow and often congested. Tourist offices and bicycle-rental facilities can provide excellent maps of cycle paths and routes. If you are tempted to try an organised bus tour, various options are available, one of which allows you to visit the city and to get on and off where you like.
