Vietnam has great domestic flight routes, making travel across the country quick and easy. You can also get some fantastic deals when you book early or if the airline is having a sale. Interestingly though, flying out of Vietnam is often cheaper than flying domestically.
If you know you are planning to fly between destinations while in Vietnam, keep an eye on flight prices as they can vary wildly and you don’t want to get stuck with a last minute pricey flight and no time to take a bus. The most popular routes, between Hanoi, Ho Chi Minh and Da Nang, will generally be the cheapest and most frequent.
Keep in mind that assigned gates often change. Make sure to listen to the announcements in case there are any changes.
