AD PLACEMENT — CONTEXTUAL
Budget extra time for the inter-terminal bus, as it can be delayed by Hanoi's notoriously congested airport road traffic.
You will go through security screening again at the second terminal, so don't assume airside-to-airside transfer.
International arrivals must clear immigration and collect any checked bags before the domestic connection, adding real time even if your onward flight is soon.
Vietnam Airlines interline and codeshare connections are the smoothest since ground staff can assist across the terminal transfer.
Signage in English is adequate but confirm your terminal at check-in, as domestic and international operations are physically separate buildings.

Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
A free shuttle bus links Terminal 1 and Terminal 2, with the ride itself taking about 10-15 minutes depending on traffic and curb congestion outside. Because the terminals are landside-connected rather than through a sterile corridor, all passengers must clear security screening again upon entering either terminal, and immigration/customs applies when arriving from or departing to international destinations.
