Match gateway to region
- Hanoi / Noi Bai (HAN): Hanoi, Ha Long, Ninh Binh and wider northern routes.
- Da Nang (DAD): Da Nang, Hoi An and much of the central coast.
- Ho Chi Minh City / Tan Son Nhat (SGN): Ho Chi Minh City, Cu Chi and southern routes.
Open-jaw before return
For an itinerary covering north and south, first compare arrival at HAN and departure from SGN—or the reverse. A superficially cheaper return ticket to one city may require another domestic flight, transfer and hotel buffer.
The right answer depends on the live international and domestic schedules, baggage and change terms. The guide provides route logic, not a fare claim.
Connection controls
- Confirm whether sectors are on one ticket or separate tickets.
- Check terminal, baggage collection and recheck requirements.
- Leave disruption time between an excursion, domestic flight and international departure.
- Do not infer a current terminal layout or shuttle from an undated blog.
Quick answers
Which airport should I use for Hoi An?
Da Nang International Airport (DAD). Vietnam Tourism describes Hoi An's Ancient Town as roughly a 50-minute drive from the airport.
Should I book Vietnam domestic flights separately?
Sometimes separate tickets are the only practical option, but they transfer more disruption and baggage risk to the traveller. Compare the complete journey and allow a larger buffer.
