Hanoi to Ho Chi Minh City
Vietnam's two great cities are about 1,150 km apart. Fly in roughly 2 hr 10 min, or ride the legendary Reunification Express the full length of the country.
Hanoi and Ho Chi Minh City sit roughly 1,150 km apart at opposite ends of Vietnam. For all but the most romantic travellers, flying is the only sensible way to cover this distance — but the Reunification Express train remains a bucket-list journey down the spine of the country.
Your options
This is the busiest air corridor in Vietnam, with frequent flights all day. The train is an experience in itself but takes well over a day.
| Mode | Approx. duration | Indicative cost (one way) | Best for |
|---|---|---|---|
| Flight | ~2 hr 10 min | ~$40–110 USD | Almost everyone — by far the fastest |
| Reunification Express (sleeper) | ~32–35 hr | ~$45–90 USD | A once-in-a-lifetime rail trip |
Costs and times are indicative; airfares swing widely with demand and how early you book.
Which option is best?
For practically every traveller, flying wins easily — Vietnam Airlines, Vietjet, and Bamboo Airways run dozens of daily flights, and a well-timed booking is often no pricier than a train sleeper while saving more than a day. The Reunification Express is for those who want the journey to be the destination: it threads through coastal towns and countryside over 32–35 hours, ideally broken into stops at places like Da Nang or Hue rather than ridden in one go.
How to book
Flights are cheapest booked online a few weeks ahead, though seats are usually available right up to departure at higher fares. Train tickets can be reserved online or at the station — sleeper berths on this iconic route sell out early, so book well in advance. For more, see the getting around Vietnam guide.
