Montréal–Trudeau International (YUL) is the city’s main international gateway and typically handles the majority of long-haul and transborder services, with full-service carriers and many low-cost transatlantic options. It sits about 20–25 minutes west of downtown (roughly 20 km) and can be reached by the 747 bus express (about 40–60 minutes, fares generally low), commuter train plus shuttle (variable time) or taxis/rideshares (25–35 minutes, mid-range fares). The airport usually offers a wide range of shops and lounges and can be more comfortable for international connections, though peak times may mean longer queues. Pros: good international connectivity and amenities; cons: can be farther from some central points and busy at peak hours. Montréal–Mirabel (YMX) historically served international flights but now functions mainly as a cargo, maintenance and occasional charter/dedicated-event airport; passenger options are limited and it is not typically used for regular commercial services. Mirabel is located about 55–70 minutes northwest of downtown (approximately 50 km) and ground access is more limited — taxis or private transfers are usually the practical choice and can be relatively costly and time-consuming compared with Trudeau. Pros: less crowded and useful for specific charters or cargo; cons: minimal passenger services and longer travel times to the city.

Bangkok is served by two main airports with distinct roles. Suvarnabhumi (BKK) is the city’s international hub, handling long-haul and full-service regional carriers such as Thai Airways and many global airlines; fares here can be mid-to-high depending on carrier and season. It sits about 30–40 km east of downtown and is usually reachable by Airport Rail Link (30–40 minutes) plus taxi (40–60 minutes), with rail fares typically low and taxis charging metered rates that can vary with traffic. Pros: modern facilities, many lounges and transfer options; cons: can be busy and transfers may take time. Don Mueang (DMK) functions mainly as a budget and domestic gateway used by low-cost carriers like AirAsia and Nok Air. Located roughly 20–25 km north of the city center, it’s often faster to access by taxi (30–50 minutes) or by bus/shuttle services (45–70 minutes), with generally lower ticket prices on budget airlines. Pros: frequent low-cost connections and simpler layouts; cons: fewer amenities and longer inter-airport transfers when connecting to international flights.
