Domestic ~60–90 minutes when quiet; international ~2.5–3.5 hours in peak banks; landside walk for every passport change.

Cabin-bag domestic guests who already know the Grab kerb can often work with about 60–90 minutes curb-to-gate when T1 is calm. International needs about 2.5–3.5 hours for check-in, aviation security, and passport control — longer on Korean / Taiwanese / Chinese bank evenings and Vietnamese holiday peaks when T2 is running ~70% over its 4M design envelope. Same-day domestic↔international always re-clears landside via the ~5-minute covered walk. Central Vietnam typhoon and flood weeks (late summer–autumn) are the reliability story more than runway length.

Two terminals, covered landside walk ~5 minutes, no sterile domestic↔intl link.

Trust FIDS and your airline: T1 is domestic; T2 is international. The official transfer page says the sheltered walk between terminals takes about five minutes — there is no sterile domestic↔international corridor. International→international connectors use the T2 transfer counter (airline-specific VIAGS / SAGS / Pacific Airlines contacts). Wrong-terminal Grab drop-offs are common with beach hotels; confirm T1 vs T2 before you leave.

City food wins on value; T2 lounges/cafés for longer airside waits.

Mỹ Khê / Han River restaurants beat most airport meals on value. If you are already through international security, T2 duty-free and dining are denser than T1. Without lounge entitlement, plan a café stop rather than a long destination dinner. Orchid / Vanda (PP) or Lotus (VNA) are the sensible longer-wait food plays.

Complete PAI + visa before landing; evening PP rooms and immigration can stack hard.

Foreign arrivals need a visa exemption, e-visa (evisa.gov.vn), or other valid entry authority — and a free Pre-Arrival Information QR from prearrival.immigration.gov.vn within three days of arrival (U.S. Embassy Vietnam notice 17 Jun 2026; DAD is in the covered airport set). Orchid Lounge 2’s temporary closure crowds the remaining Orchid room in the 21:00–22:30 peak — have a Vanda or gate-seat backup. T2 expansion and T1 renovation works mean temporary wayfinding changes; follow live terminal signs.
