✈️ Flight Guide: Montreal (YUL) → Ho Chi Minh City (SGN)

Major events and festivals drive demand and often raise economy fares from Tan Son Nhat International Airport (SGN). Tet (Vietnamese Lunar New Year) typically causes high domestic and regional demand—book at least 8–12 weeks ahead; similarly, international events such as Singapore National Day or large conferences in Bangkok increase prices to hubs like SIN and BKK. If you must travel during festivals, search for flights early, consider flying on the fringe dates, and explore secondary airports for potential savings.

The cheapest months to fly from Tan Son Nhat International Airport (SGN) are typically the shoulder seasons—March and September—when demand is lower and airlines run promotional sales. Mid-week departures (Tuesday to Thursday) often yield lower economy fares than weekend travel; early-morning and late-night flights can also be less expensive. Avoid peak local holiday periods like Tet (Vietnamese Lunar New Year) and major international holidays when prices spike; if you must travel then, book 8–12 weeks in advance to secure the best economy rates.

Direct flights from Tan Son Nhat International Airport (SGN) generally save time and reduce connection risk but can cost more in economy class compared to multi-leg itineraries using budget carriers via hubs like Kuala Lumpur or Singapore. Connecting flights can be significantly cheaper if you are flexible and allow sufficient layover time, but watch for separate-ticket risks—book protected connections when possible or use itinerary combinations supported by the same alliance to ensure baggage through-check. For cheapest economy travel, compare total trip cost (including baggage and transfer fees) rather than just base fare, and consider overnight layovers in major hubs if it leads to strong savings.

Major carriers serving Tan Son Nhat International Airport (SGN) include Vietnam Airlines (full-service), VietJet Air (low-cost), Bamboo Airways (hybrid), AirAsia (regional low-cost), and international full-service carriers on select routes. Vietnam Airlines offers greater baggage allowances and connectivity but at a higher base fare; VietJet and AirAsia provide very low base fares for economy travelers willing to pay for add-ons like checked luggage and seat selection. For the cheapest economy fares, monitor low-cost carrier flash sales and compare total cost after adding essential extras.

In the dry season (December–April) demand to beach and city destinations often rises; book early to secure cheap economy seats. During the wet season (May–November) you may find lower fares but allow flexibility for weather disruptions. For seasonal savings, travel in shoulder months (March, September) and avoid local holiday peaks; pack smart for weather differences (light rain gear in wet season) and pre-purchase baggage online to avoid higher airport fees.
