Batik Air adds Subang flights to Miri, Sibu and Bali

Batik Air Malaysia plans to open three direct routes from Sultan Abdul Aziz Shah Airport in Subang this December. Miri and Sibu flights are scheduled to start on December 1, 2026, followed by Bali on December 2.

The three routes do not share one timetable. Miri and Sibu are each planned three times a week on Tuesday, Thursday and Saturday. Bali is planned four times a week on Monday, Wednesday, Friday and Sunday. The Bali date also replaces an earlier October 20 plan, so an old article or saved search may now be wrong.

*Original AI-generated OpenSim editorial illustration. The aircraft, airport and combined landscape are conceptual, not a Batik Air aircraft, an exact terminal view or a route map.*

The practical answer: Search the exact airport pair and date before paying. Use SZB for Subang, MYY for Miri, SBW for Sibu and DPS for Bali. Miri and Sibu are planned from December 1; Bali is planned from December 2 after its launch was moved from October. Treat the itinerary issued by Batik Air as the final word on availability, times, baggage and operating carrier.

This guide was checked on October 13, 2026. All three services were still future flights, so it does not claim that normal operations have begun.

The planned Subang schedules

The October 13 Batik Air statement reported by DagangNews gives the launch dates and weekly frequencies. Current filed-schedule reporting supplies the flight numbers, days and local times.

Malaysia and Bali use the same UTC+8 time zone, so no clock adjustment is needed when reading these times. The filed schedules list Boeing 737-800 equipment. That is a plan, not a guarantee for every departure, because airlines can change aircraft and times.

The Miri and Sibu timetable comes from AeroRoutes' October 10 schedule report. Its Bali update records the move from October 20 to December 2. Check the live booking result and issued ticket before arranging a hotel, tour or separate connection.

Why the revised Bali date matters

The Subang to Bali route was previously filed for October 20. The current schedule filing moves the planned start to December 2 while retaining four weekly flights. Anyone who researched the route in September may still have the old date, earlier times or a stale reminder.

Do not assume that an October listing remains valid. Search SZB to DPS for the exact travel date and confirm OD312 or OD313 on the result. If a trip was built around the earlier launch, open the booking directly or contact the seller that issued the ticket. A news article cannot establish the status of an individual reservation.

The Miri plan also changed between proposal and filing. September reporting described a possible four-weekly service subject to approval. The newer airline statement and filed schedule show three flights a week. For December planning, use the newer Tuesday, Thursday and Saturday pattern unless Batik Air changes it again.

Make sure Subang is the airport you intend to use

SZB is Sultan Abdul Aziz Shah Airport in Subang. It is not Kuala Lumpur International Airport, whose code is KUL. A search for “Kuala Lumpur” can show both airports, so check the code before payment and again before arranging transport.

Subang Airport's departure guidance says passengers should use the flight-information screens to find the check-in row and bring the travel documents required for the trip. It says counters open at least two hours before departure, while warning that airline procedures vary.

Use Batik Air's instruction for the selected flight rather than treating two hours as a universal cutoff. Leave extra road time for a December departure and for an international flight to Bali. If another flight arrives at KUL, transferring to SZB is a road journey between different airports, not a walk between terminals.

Check the fare and baggage before payment

Baggage is determined by the fare and itinerary. The route announcement does not establish one cabin or checked allowance for all three destinations. Open the fare details and save the baggage line shown before payment.

Batik Air Malaysia's Manage Booking service says pre-purchased additional baggage must be completed at least 12 hours before scheduled departure. That deadline does not guarantee that an extra is offered for every booking or that an airport purchase will cost the same.

Do not combine allowances from two passengers or split weight across extra bags unless the booking rules expressly allow it. The same caution applies to a separate onward flight: its carrier and fare can have a different limit. Keep medicine, documents, chargers and valuables in cabin baggage within the applicable safety and size rules.

Domestic Sarawak flights and the Bali flight need different preparation

Miri and Sibu are domestic Malaysian routes. Bali is an international route to Indonesia. That difference changes the document, immigration and arrival steps even though all three flights leave Subang.

For Miri or Sibu, carry the identity or travel document required for the passenger and itinerary. The Malaysian Immigration Department's domestic-travel guidance lists accepted documents for travel involving Sarawak and says a valid pass is required where applicable. A domestic ticket does not mean every traveler can ignore document checks. Confirm the requirement for the traveler's citizenship and status before departure.

For Bali, check passport validity, visa or visa-free eligibility and the current arrival process for the traveler's nationality. Indonesia's immigration service says international arrivals at I Gusti Ngurah Rai Airport use the All Indonesia arrival declaration. It can be completed during the three days before arrival and combines immigration, customs, health and quarantine information. It is not a visa.

Ngurah Rai Immigration's current foreign-national guidance lists visa-free and visa-on-arrival categories, but eligibility depends on nationality and purpose. Check the official list instead of copying the rule that applied to another traveler.

Protect separate connections at Miri, Sibu and Bali

Three-weekly service leaves fewer same-route recovery options than a daily flight. If OD1120, OD1121, OD1132 or OD1133 is part of a longer journey, check whether the next segment is on the same ticket. A separately booked flight, bus, boat, tour or hotel deadline is not automatically protected when the first flight changes.

Miri can be a starting point for journeys toward Brunei or northern Sarawak, while Sibu often feeds road and river travel through central Sarawak. Bali arrivals may continue by road or fast boat. None of those onward arrangements should be timed from the scheduled landing minute alone.

Allow for baggage collection, document checks where applicable and ground traffic. For a high-cost or last departure, compare an overnight buffer with the financial risk of missing the connection.

Mobile data for Sarawak and Bali

A Malaysia OpenSim eSIM can fit a domestic trip from Subang to Miri or Sibu. An Indonesia OpenSim eSIM can fit time in Bali. For a journey that includes both countries, compare the Singapore, Malaysia, Vietnam, Thailand and Indonesia regional plan with buying separate country plans.

The public catalog was checked on October 13 and returned 33 Malaysia packages, 32 Indonesia packages and four packages for that five-country combination. Those counts can change. Read the selected card for its current coverage, allowance, validity, speed, hotspot support, activation instructions and top-up eligibility.

An eSIM supplies mobile data. It does not change an airline booking, protect a separate connection, provide a local phone number unless the package says so or extend a transport app beyond its operating area. Install while reliable Wi-Fi is available, then follow the selected plan's activation instructions.

Ten questions about Batik Air's new Subang flights

When do the new Batik Air Subang flights start?

Subang to Miri and Sibu are planned from December 1, 2026. Subang to Bali is planned from December 2. These were future launch dates when checked on October 13.

Which days will Batik Air fly from Subang to Miri and Sibu?

Both domestic routes are filed for Tuesday, Thursday and Saturday. They are not planned as daily services, so search the exact date in both directions.

Which days will Batik Air fly from Subang to Bali?

OD312 and OD313 are filed for Monday, Wednesday, Friday and Sunday. The planned frequency is four flights a week.

Did the Subang to Bali launch date change?

Yes. It was previously planned for October 20, 2026. The current filed schedule moves the start to December 2, so older articles and saved searches may show superseded information.

Is Subang Airport the same as KLIA?

No. Subang is SZB and Kuala Lumpur International Airport is KUL. They are separate airports. Check the code before paying and allow a road transfer if an itinerary uses both.

What baggage is included on these Batik Air flights?

Use the allowance displayed for the selected fare and save it with the confirmation. The route announcement does not prove one allowance for every fare, date or passenger.

Can I add Batik Air baggage after booking?

Batik Air's Manage Booking page supports extras for eligible reservations and says additional baggage should be pre-purchased at least 12 hours before departure. Availability and price depend on the booking.

How early should I arrive at Subang Airport?

Follow the instruction on the ticket. Subang Airport says counters open at least two hours before departure, but the airline's requirement can vary. Add time for traffic, baggage and international document checks where relevant.

Do I need Indonesia's arrival declaration for Bali?

International arrivals at Bali use the All Indonesia declaration under current immigration guidance. Complete it within the permitted three-day window. It does not replace a visa or nationality-specific entry check.

Will one eSIM work in Malaysia and Indonesia?

Only if the exact package lists both countries. Malaysia and Indonesia country plans are separate. The linked five-country option covers both, but its live package terms still control.

Before booking

• Search the exact airport pair and travel date.
• Confirm SZB rather than KUL.
• Use Tuesday, Thursday and Saturday for Miri or Sibu searches.
• Use Monday, Wednesday, Friday and Sunday for Bali searches.
• Treat December 2 as the current Bali plan, not October 20.
• Save the flight number, local times and fare rules.
• Check baggage before payment and extras well before departure.
• Leave a buffer for any separately booked onward journey.
• Check the right documents for Sarawak or Indonesia.
• Keep the itinerary, arrival forms and eSIM instructions available offline.

Evidence for the three routes and update triggers

The October 13 airline statement supports the three destinations, launch dates and frequencies. AeroRoutes supports the filed flight numbers, times, days and planned 737-800 equipment, including the revised Bali date. Miri reporting was used to corroborate the domestic launch and distinguish the newer three-weekly filing from the earlier proposal.

Subang Airport supports the departure-process guidance. Batik Air's Manage Booking page supports the extra-baggage deadline. Indonesian immigration sources support the Bali arrival declaration and nationality-specific visa checks.

Public traveler discussions were used to identify recurring questions about baggage weight, handbag treatment, airport arrival time, online check-in, seat handling, added baggage, Subang transport and onward travel in Sarawak. They were not used as proof of airline, airport or government policy.

OpenSim will update this page after independent confirmation of the first flights, or if Batik Air publishes a material launch-date, timetable, frequency, baggage, check-in or route-status change.
