Here’s everything you need to know before booking your Hanoi to Bangkok flight.

Low-Cost Airlines: VietJet Air, Thai AirAsia & Thai Vietjet
Low-cost airlines are the most affordable way to get from Hanoi to Bangkok. Thai AirAsia is one of the busiest airlines on the route and flies into Don Mueang, while VietJet Air and Thai Vietjet land at Suvarnabhumi. Expect compact seats, no complimentary meals, and extra fees for checked baggage and seat selection, so compare the total price, not just the base fare.
Full-Service Airlines: Vietnam Airlines & Thai Airways
If you prioritize comfort and convenience, Vietnam Airlines and Thai Airways are both excellent options. These full-service carriers include checked baggage, a meal or snack, and more generous legroom, which makes the short journey noticeably more comfortable.
Vietnam Airlines runs the most nonstop flights on the route, usually several per day, so it’s easy to find a departure time that suits you. Thai Airways is a good choice if you’re connecting to other destinations in Thailand, as it’s easy to transfer to domestic flights at Suvarnabhumi.
How Long Is the Flight from Hanoi to Bangkok?
The nonstop flight time from Hanoi’s Noi Bai Airport to Bangkok is about 1 hour 45 minutes to 2 hours, covering roughly 993 km (617 miles). Vietnam and Thailand share the same time zone (UTC+7), so there’s no time change and no jet lag. Flights depart throughout the day, from early morning until late evening, giving you plenty of flexibility.
Booking Your Flight: Timing and Tips
Compare fares across airlines before you book.
For most of the year, booking three to eight weeks in advance gives you a good choice of fares and flight times. During peak periods, such as Tet (Lunar New Year), Songkran in mid-April, and the Christmas and New Year holidays, prices can rise sharply, so it’s worth booking two to three months ahead.
Comparison tools like Google Flights or Skyscanner make it easy to compare all airlines at once and set price alerts for your dates. When comparing, remember to add baggage fees for low-cost airlines and check whether the flight lands at Suvarnabhumi or Don Mueang.
Airport Tips: Noi Bai, Suvarnabhumi & Don Mueang
Suvarnabhumi Airport is Bangkok’s main international gateway.
Noi Bai International Airport (HAN): International flights depart from Terminal 2. Arrive at least 2 to 3 hours before departure to allow time for check-in, security, and immigration, especially during Tet and other holidays.
Suvarnabhumi Airport (BKK): Bangkok’s main international airport, used by Vietnam Airlines, Thai Airways, VietJet Air, and Thai Vietjet. It’s large and modern, and the Airport Rail Link runs directly into central Bangkok.
Don Mueang Airport (DMK): Bangkok’s older airport, north of the city, and the main base for Thai AirAsia. It’s convenient for northern areas of the city, and it’s connected to the SRT Red Line train and airport buses to the BTS Skytrain.
Entry Requirements for Thailand
Vietnamese passport holders can visit Thailand visa-free for up to 30 days. Many other nationalities can also enter visa-free for short stays, but the rules vary by passport, so check the latest requirements with the Thai embassy or official government websites before you book.
All foreign visitors must also complete the Thailand Digital Arrival Card (TDAC) online before arrival. Make sure your passport is valid for at least six months from your arrival date.
Getting from Bangkok Airport to the City
Bangkok’s BTS Skytrain is a quick way to get around the city after you land.
From Suvarnabhumi, the Airport Rail Link is often the fastest way into central Bangkok, especially during rush hour. It connects with the BTS Skytrain at Phaya Thai and the MRT metro at Makkasan. Taxis and Grab are easy to find at both airports, and the ride to areas like Sukhumvit, Silom, or the riverside usually takes 30 to 60 minutes, depending on traffic.
From Don Mueang, you can take the SRT Red Line train, airport buses to the BTS Skytrain, or a taxi or Grab. Planning to continue your trip? See our guide to getting from Bangkok to Chiang Mai by flight, train, and bus, or explore more Thailand travel guides.
Other Travel Options: Flying vs. Bus or Train
Flying is by far the quickest and most practical way to travel between Hanoi and Bangkok. There’s no direct train between the two cities, and overland travel usually means combining a long-distance bus from Hanoi to Vientiane in Laos with a border crossing to Nong Khai, then an overnight train or bus to Bangkok. The whole journey typically takes a day and a half or more.
If you have plenty of time and want an adventure, the overland route lets you see Laos along the way. But for most travelers, a 2-hour flight is hard to beat for time, comfort, and often price.
