AD PLACEMENT — CONTEXTUAL
Never book a connection that requires switching between the Domestic and International terminals unless you have at least two hours, since there is no airside link.
If arriving internationally, budget significant time for Vietnamese immigration and baggage claim before you can even head toward the domestic side.
Check whether you need a Vietnam visa or e-visa in advance, as processing delays at immigration can eat into any connection buffer.
Use the free inter-terminal shuttle bus rather than walking with luggage in Ho Chi Minh City's heat and humidity.
Domestic-to-domestic connections on Vietnam Airlines or VietJet within Terminal 1 are the smoothest option if your itinerary allows routing that way.

Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
There is no airside walkway linking Terminal 1 and Terminal 2; passengers exit one terminal building, cross a short roadway or take a free shuttle bus, and enter the other terminal from landside. Full re-screening through security is required for every terminal change, and international arrivals must also clear Vietnamese immigration before doing anything else. During peak periods the shuttle and curb can add real delay on top of the walk itself.
