Thai Vietjet Kuala Lumpur-Bangkok flights: daily guide

Thai Vietjet began daily nonstop flights between Kuala Lumpur and Bangkok Suvarnabhumi on October 9, 2026. Flight VZ681 leaves Kuala Lumpur in the afternoon, while VZ680 flies the return sector from Bangkok before midday.

The route uses Kuala Lumpur International Airport and Suvarnabhumi Airport, not Bangkok's Don Mueang Airport. Check those airport names as well as the flight number before booking transport or a separate connection.

The practical answer: Thai Vietjet's KUL-BKK service is operating daily. The published inaugural timetable has VZ681 leaving Kuala Lumpur at 3:15 p.m. and arriving at 4:30 p.m., with VZ680 leaving Bangkok at 11 a.m. and arriving at 2:10 p.m. All times are local. Use the itinerary issued for your date because schedules can change.

This guide was checked on October 9, 2026, after the inaugural flight arrived.

Thai Vietjet's daily Kuala Lumpur-Bangkok schedule

The Tourism Authority of Thailand confirmed the first service on October 9. It described Kuala Lumpur as Thai Vietjet's first direct route to Malaysia and published this timetable:

The airline's current Kuala Lumpur to Bangkok booking page also offers the route. The inaugural service used a 189-seat Boeing 737-8, but an aircraft can change for an individual flight.

Malaysia and Thailand use different time zones: Kuala Lumpur is one hour ahead of Bangkok. Read the itinerary in local time rather than trying to calculate the trip from the clock times alone.

Use KUL Terminal 2 and Bangkok Suvarnabhumi

Thai Vietjet's flight uses Kuala Lumpur International Airport, whose low-cost terminal is identified by Malaysia Airports as KLIA Terminal 2. Flight schedule services currently list VZ681 from Terminal 2, but the boarding pass and airport display are the final authority for the day's counter, gate and terminal.

The Bangkok airport code is BKK, which means Suvarnabhumi Airport. It is not Don Mueang, whose code is DMK. That distinction matters when arranging a pickup or connecting to a flight sold from Bangkok's other airport.

If a separate ticket leaves from DMK, allow for immigration, baggage collection, ground travel across Bangkok and the next airline's check-in deadline. A same-day airport change is not a protected connection.

Check in before Thai Vietjet's international deadline

Thai Vietjet's current passenger FAQ says its international check-in counter closes 50 minutes before scheduled departure. It asks passengers to be at the gate at least 30 minutes before departure, and the gate closes 15 minutes before departure.

Online check-in is available only for eligible flights and passengers. The airline publishes a window from 24 hours to one hour before departure at supported airports, with exclusions. If the booking does not offer online check-in, use the airport counter and arrive with enough time for document checks, security and outbound immigration.

Do not treat successful online check-in as permission to arrive at the gate just before closure. A document check, bag drop or busy immigration queue can still require more time.

Match the baggage allowance to the fare

Thai Vietjet's FAQ allows one main cabin bag plus one small personal item, with a combined maximum weight of 7 kilograms. The main item can measure up to 56 by 36 by 23 centimetres.

Published checked-bag inclusion depends on the fare. The FAQ currently lists 30 kilograms for SkyBoss, 20 kilograms for Deluxe and no included checked baggage for Eco. The booking confirmation controls if a promotion, add-on or later policy change produces a different allowance.

Measure and weigh the packed cabin bags together. If checked baggage is needed, compare the final fare after adding it rather than assuming the lowest search result includes a suitcase.

Protect separate onward tickets

Thai Vietjet describes itself as a point-to-point carrier and says it is not responsible for a passenger's separate onward flight. A second booking is therefore not protected in the same way as a through itinerary.

For an onward international flight, allow time to enter the country when required, collect checked bags, change terminal or airport if necessary, and complete the next carrier's check-in. Travel insurance may help with some missed connections, but only when the policy terms cover the circumstances.

Daily service gives more recovery options than a route that flies once or twice a week. It still does not guarantee a same-day seat if a flight is disrupted or full. Keep the airline contact details and the next workable journey available offline.

Mobile data in Kuala Lumpur and Bangkok

A Malaysia OpenSim eSIM can cover ground-based mobile data on the Kuala Lumpur side, while a Thailand OpenSim eSIM can cover the Bangkok side. For a trip that needs data in both countries, compare the Singapore, Malaysia and Thailand regional eSIM with buying two country plans.

The public OpenSim catalog was checked on October 9. It listed purchasable options for all three destinations. Price, allowance, validity, network, hotspot support and top-up eligibility vary by package and can change, so read the selected plan before paying.

An eSIM provides mobile data after landing on a compatible, unlocked phone. It does not provide inflight Wi-Fi, protect a flight connection or extend an app's service area. Install it while dependable Wi-Fi is available and keep boarding details and addresses saved offline.

Ten questions about Thai Vietjet Kuala Lumpur-Bangkok flights

Is Thai Vietjet already flying between Kuala Lumpur and Bangkok?

Yes. The inaugural KUL-BKK service operated on October 9, 2026, and the announced schedule is daily. Check the live itinerary for the date before leaving for the airport.

What are the VZ681 and VZ680 flight times?

The inaugural timetable lists VZ681 from Kuala Lumpur at 3:15 p.m., arriving in Bangkok at 4:30 p.m. VZ680 leaves Bangkok at 11 a.m. and arrives in Kuala Lumpur at 2:10 p.m. Times are local and can change by travel date.

Does Thai Vietjet use KLIA Terminal 1 or Terminal 2?

Current schedule information lists VZ681 from KLIA Terminal 2. Confirm the terminal on the boarding pass and the airport's departure display because operational assignments can change.

Does this flight arrive at Bangkok BKK or Don Mueang?

It arrives at Suvarnabhumi Airport, code BKK. Do not book a Don Mueang pickup or connection unless you have planned the cross-city transfer yourself.

Can I check in online for a Thai Vietjet international flight?

Only when the flight and passenger are eligible at a supported airport. Thai Vietjet publishes an online window from 24 hours to one hour before departure. Use the airport counter if the option is unavailable.

What time should I reach the airport for VZ681 or VZ680?

Build in time for document checks, security and immigration. The international counter closes 50 minutes before departure, the airline asks passengers to reach the gate 30 minutes before departure, and boarding closes 15 minutes before departure.

What is Thai Vietjet's 7 kg cabin-bag rule?

Thai Vietjet currently allows one main cabin bag and one small personal item weighing no more than 7 kilograms combined. The main bag can measure up to 56 by 36 by 23 centimetres.

Does the cheapest Thai Vietjet fare include checked baggage?

The airline's current FAQ says Eco has no included checked baggage, Deluxe has 20 kilograms and SkyBoss has 30 kilograms. Check the selected fare and confirmation before paying because inclusions can change.

Will Thai Vietjet protect a separately booked connection?

Do not assume it will. The airline operates on a point-to-point basis and disclaims responsibility for a separate onward flight. Leave a substantial buffer and understand the second ticket's no-show rules.

Which OpenSim eSIM works in both Malaysia and Thailand?

The Singapore, Malaysia and Thailand regional plan is the most direct two-country match. Compare its current allowance, validity and price with separate Malaysia and Thailand plans for the actual trip.

Before booking

• Confirm the KUL-BKK or BKK-KUL airport pair and the daily nonstop label.
• Read the departure and arrival times in local time.
• Use KUL Terminal 2 as current guidance, then check the issued boarding pass.
• Remember that BKK is Suvarnabhumi, not Don Mueang.
• Compare the total after bags, seats and any flexibility you need.
• Check whether online check-in is offered for the specific booking.
• Reach the counter before the 50-minute international cutoff.
• Leave a realistic buffer for any separate flight or Bangkok airport change.
• Save the itinerary, hotel address and backup flight offline.
• Choose mobile data only after checking the plan's countries and activation rule.

Verification sources for VZ681 and VZ680

The Tourism Authority of Thailand confirms the inaugural operation, daily frequency, flight numbers, published timetable and launch aircraft. Thai Vietjet's booking page confirms that the route is sold, and its FAQ supports the baggage, check-in and point-to-point guidance. Malaysia Airports and Airports of Thailand support the airport identities. Independent schedule pages were used to cross-check the airport pair and operating pattern, not to override airline or airport information.

Public traveler discussions helped identify questions about online check-in, airport queues, combined cabin-bag weight, checked baggage and self-transfers. They were not used as proof of airline policy.

We will update this page if Thai Vietjet changes the frequency, timetable, terminal guidance, baggage allowance, check-in rules or route status.
