Montréal is served primarily by Montréal–Trudeau International (YUL), the region’s main international hub handling long-haul and transborder flights and home to full-service carriers alongside several international and low-cost airlines. It sits about 20–25 minutes (20 km) west of downtown by car; express buses, commuter trains, taxis and ride‑shares typically take 25–40 minutes depending on traffic, with fares ranging from economy transit prices to moderate taxi/ride-share rates. For budget travelers, Montréal–Mirabel (YMX) now functions largely for cargo and some charter operations rather than regular passenger service, so most leisure and business travelers use Trudeau. Pros: wide route network and modern passenger facilities; cons: peak-hour road congestion and variable parking/transfer costs.
