Flights to Vietnam from Thailand — Routes, Airlines, THB Fares | 2026

Flights to Vietnam from Thailand: the SiamFlights catalogue lists 5 routes from 2 Thai airports, flown by Thai Airways, Vietnam Airlines, Thai AirAsia, Thai Vietjet and VietJet Air. This is a cluster D — ASEAN & regional leisure corridor. Local currency VND; fares are shown in THB.

Visa & currency — Vietnam

We record 0 visa rule(s) for a Thai passport travelling to Vietnam, where the local currency is VND, across 4 corridors from 2 Thai airports in our catalogue. Visa rules attach to the passport’s nationality, never to the airline or the fare.

Thai passport to Vietnam: visa-free 30 days (ASEAN). Keep passport valid ≥6 months. Local currency VND. Verify current rules at mfa.go.th before buying a ticket.

The fare is in baht; the trip is not. Every price here is quoted in THB while ground costs at the destination are in VND. Exchange spread and card conversion fees are the line most often omitted when comparing a whole-trip budget. Choosing to be charged in baht on a foreign terminal means accepting the merchant’s rate, which is almost never better than your issuing bank’s.

Companions on other passports sit under other rules. A family or group holding different nationalities can face entirely different requirements on the same flight to Vietnam. Check each person separately before booking as a group, and do not infer from what a group member experienced before — requirements change between two trips.

Routes to Vietnam from Thai airports

Our catalogue holds 4 corridors from Thailand to Vietnam, leaving 2 Thai airports for 2 destination airports, roughly 133 departures a week combined, block times 1.7–1.8 hours. Local currency is VND while every price here is quoted in THB.

The route guides carry what this table cannot. This is a country-level summary; each city-pair page holds monthly readings, the weekly fare series we have captured, and carrier detail per corridor. If you already know your city pair, start there — the picture will match your plan far more closely.

The departure airport moves the price more than expected. Corridors to Vietnam leave from 2 Thai airports, and fares from regional airports usually sit above Bangkok’s because capacity is thinner. Positioning into Bangkok first and connecting internationally is sometimes cheaper than flying direct from the region — but done on two tickets you carry the whole connection risk yourself. Weigh both before deciding.

Airlines flying to Vietnam

5 carriers serve Vietnam corridors in our catalogue, with baseline allowances from 7 to 30 kg. Of the 4 we hold an airline row for, 1 are registered in the destination country, 3 in Thailand and 0 are third-country carriers.

The 7–30 kg range is two pricing models on one corridor. The low end is unbundled fares selling baggage separately; the high end full-service fares including it. On journeys to Vietnam, which often carry more luggage than average, the excess-weight gap can exceed the fare gap outright. Always compute the total with your real bags before deciding.

This lists carriers on the corridor, not every way of getting there. We show the airlines recorded on direct routes from Thailand to Vietnam. Connecting itineraries through regional hubs do not appear here and are sometimes materially cheaper. The trade is time plus one more point where the plan can break — compare total price against total journey time, not price alone.

Vietnam corridor character

Corridors to Vietnam average about 1.8 hours of block time, split 4 short-haul (<4h). The lowest fare we have recorded is ฿4,530 on BKK–HAN. Combined frequency is roughly 133 departures a week. Local currency is VND while every price here is quoted in THB.

Routes to Vietnam from Thailand are a cluster D — ASEAN & regional leisure corridor. The average block time is about 1.7 hours. The lowest fare our feed returned across this country’s corridors is about ฿4,647 on BKK-SGN (it moves with season). Compare month-by-month fares for each city pair on the route pages.

Who travels this corridor, and why that moves the price. The cluster split to Vietnam is ASEAN & regional leisure (4). Demand tied to a fixed calendar — pilgrimage seasons, contract cycles — spikes in the same weeks every year, unlike leisure demand which spreads. If your corridor sits in a calendar-locked group, booking early does more for the price than comparing airlines.

An average block time hides what matters. The 1.8-hour figure averages corridors of unequal length, and block time drives preparation more than people expect. Beyond six hours, meals, seat choice and sleeping on board become real variables; below it they barely register. Read the block time for the city pair you will actually fly, not the country average.

Best time to book

Across the 9 months we captured on corridors to Vietnam, the cheapest reading was Aug 2026 at ฿2,520 and the dearest Apr 2027 at ฿4,654 — a 85% spread. These are observations, not forecasts. We hold 4 corridors from 2 Thai airports to 2 destination airports.

Fares to Vietnam are cheapest outside Thai school holidays, Songkran and New Year. Book 4–8 weeks ahead; compare months in the route table and city-pair pages.

A cheap non-changeable fare has a hidden cost. The lowest fares usually carry no-change, no-refund conditions. If your documents, visa or schedule are not yet settled, the saving is routinely smaller than the replacement ticket you will buy when something moves. The safe order is paperwork first, price lock second.

Read the 85% spread correctly. The gap between cheapest and dearest month is what flexibility is worth across this group. It is computed from the lowest value we captured in each month, and those can come from different corridors month to month, so it is a country-level picture rather than any one city pair’s price curve. Use it to choose a month, then price the actual route on its own page.

Departure airports for Vietnam

Corridors to Vietnam depart from 2 Thai airports in our catalogue, each with a different route count and frequency — which feeds directly into the fare and into the options you have when a flight is cancelled. 5 carriers appear across those corridors.

• Bangkok (BKK) — 2 routes, ~91×/wk
• Bangkok (DMK) — 2 routes, ~42×/wk

Each airport page carries the full network. The links above lead to airport pages listing every direct corridor from that airport, not only those to Vietnam. That is useful when comparing where to depart from, or when looking for a fallback routing through another regional hub.

Positioning into Bangkok is an option worth thinking through fully. If you are outside the capital and direct service to Vietnam from your nearest airport is thin or expensive, flying into Bangkok and connecting internationally is often cheaper. The condition that matters is keeping the whole journey on one ticket. Split it and you absorb the connection risk, a second baggage charge and a fresh check-in yourself.

Passenger rights on flights to Vietnam

We hold 4 corridors from 2 Thai airports to 2 destination airports. Departures from Thailand to Vietnam fall under Thailand CAAT; the return falls under Vietnam CAAV. What you are owed changes with the direction of travel and the operating carrier’s nationality — not with the fare you paid or the cabin you sat in.

No European-style compensation schedule applies here. The destination sits with Vietnam CAAV, which typically imposes duty of care, re-routing and refund obligations but no fixed EU261-style cash bands. The enforceable floor is therefore the airline’s own conditions of carriage plus Thailand CAAT rules for departures from Thailand. Read the conditions of carriage before you buy — that is the document that actually binds you.

Baggage loss and delay run on a separate rulebook. An airline’s liability for baggage that is lost, damaged or delayed on an international journey sits under the Montreal Convention 1999 where both the origin and destination states are parties. The caps are denominated in SDR and revised periodically, so only the current figure is usable. This frame is entirely separate from delay compensation: you can have no compensation claim and still have a baggage claim.
