STARLUX Taichung-Sapporo flights: schedule and bags

STARLUX scheduled nonstop flights between Taichung and Sapporo from October 2, 2026. The first timetable runs five times a week, but the frequency and local times change later in the autumn.

That change matters when comparing dates. Check the exact JX318 or JX319 departure before committing to a separate connection, ski transfer or hotel outside Sapporo.

The practical answer: JX318 flies from Taichung International Airport (RMQ) to New Chitose Airport (CTS), and JX319 returns to Taichung. The October 2 to 24 pattern is Monday, Tuesday, Wednesday, Friday and Saturday. STARLUX publishes a different three-day pattern from October 27 to November 28, followed by daily service from December 1 to March 27.

This guide was checked on October 2, 2026, after the route's scheduled launch time.

The route has three timetable periods

STARLUX's launch announcement set October 2 as the start date and published five nonstop flights a week through the first booking period. Its current route page shows bookable travel from October 2 to 24.

The airline has separately published its winter Taichung schedule. That changes the operating days and shifts both flights later from October 27. Daily service is then listed from December 1 through March 27, 2027.

All times below are local. Japan is one hour ahead of Taiwan.

STARLUX's published blocks do not list this route on October 25 or 26, or on November 29 or 30. Do not assume those dates are available from the surrounding frequency. Search the individual date before making a nonrefundable plan.

New Chitose is the airport for Sapporo

The Sapporo airport code on this route is CTS, which means New Chitose Airport, not Okadama Airport. New Chitose is southeast of central Sapporo and has a rail station on basement level B1 of the terminal building.

The airport says the JR trip to Sapporo takes about 30 minutes without a transfer. JR Hokkaido also warns that not every Airport train continues to Otaru, and travelers heading toward Niseko must change at Otaru. Check the destination shown on the train before boarding.

Autumn and winter weather can affect rail and road travel in Hokkaido. A same-day ski-area transfer or separate domestic flight needs more room than the timetable's fastest transfer. Save the accommodation address and last practical transfer option before departure.

Price the ticket and baggage together

STARLUX allows one 7 kg cabin bag in economy, with maximum dimensions of 56 by 36 by 23 cm, plus one personal item up to 40 by 30 by 10 cm. Business class allows two cabin bags weighing up to 14 kg in total, with no individual piece above 10 kg.

Checked baggage depends on the fare product. The current STARLUX fare table gives Economy Limited and short-haul Economy Saving one 23 kg piece. Economy Basic and Full include two 23 kg pieces. The e-ticket remains the final allowance, especially on a mixed-cabin or connecting itinerary.

This matters for Hokkaido trips with winter clothing or ski equipment. Price the complete baggage plan before choosing the lowest fare, and check the airline's special-baggage rules before treating sports equipment as an ordinary checked bag.

Online check-in closes one hour before departure

STARLUX opens online check-in 48 hours before non-US flights and closes it one hour before departure. Passengers with checked baggage should complete bag drop at least one hour before the flight.

The airline says airport counters generally open between two and three and a half hours before departure and close one hour before departure. Those are cutoffs, not suggested arrival times. Document checks, baggage, security and the walk to the gate all need time.

Travelers who need mobility support or another special service should arrange it with the airline and arrive earlier. STARLUX advises passengers needing special assistance to complete airport check-in at least two hours before departure.

Entry steps depend on the passport

Flying nonstop does not remove immigration or customs requirements. Japan's Digital Agency describes Visit Japan Web as an online service for immigration and customs arrival procedures. It can reduce form-filling after arrival, but it does not replace a passport or any visa required for the traveler.

For the return direction, foreign visitors who are required to file Taiwan's digital arrival card should use the official Taiwan Arrival Card site. Check the current entry rules for the passport being used, including any visa or stay-limit conditions, rather than relying on another traveler's eligibility.

Keep the first night's address, onward itinerary and entry confirmation accessible offline. Airport Wi-Fi or mobile service can be congested just when a QR code or booking reference is needed.

Separate connections need a real buffer

A direct Taichung-Sapporo flight may still sit inside a longer journey. STARLUX says baggage on a single-ticket interline itinerary can be tagged to the final destination when the connection qualifies, but government, airport and timing restrictions can still require collection and recheck.

Separate tickets are different. STARLUX's interline baggage policy says passengers connecting on a separate ticket must collect and recheck their bags. A late inbound flight also does not automatically protect the next booking.

This is especially important around the three-times-weekly late-October and November pattern. If a missed flight cannot be recovered the same day, the lowest-cost self-transfer can become the most expensive option.

Mobile data for Sapporo and a Taiwan-Japan trip

For a trip entirely within Japan, compare the live Japan OpenSim eSIM. Travelers who need one plan across Taiwan and Japan can compare Asia 12 areas and Asia 20 areas; both current coverage lists include Taiwan and Japan.

OpenSim's public catalog was checked on October 2. Confirm the selected plan's allowance, validity, hotspot support, speed policy and top-up eligibility before paying. Not every plan is reloadable, and a regional plan only helps in the countries named in its own coverage list.

Install the eSIM on reliable Wi-Fi before departure, then follow the chosen package's activation rule. Mobile data can help with airline alerts, Visit Japan Web, maps and rail updates after landing. It does not replace inflight Wi-Fi, immigration documents or protection for a separate ticket.

Ten questions about STARLUX Taichung-Sapporo flights

Is the Taichung-Sapporo route operating now?

STARLUX set October 2, 2026 as the launch date and lists bookable flights from that date. Check the airline's flight-status page for the individual service because a published route schedule is not a live operational guarantee.

Which days does STARLUX fly from Taichung to Sapporo in October?

From October 2 through 24, the published pattern is Monday, Tuesday, Wednesday, Friday and Saturday. From October 27, it changes to Tuesday, Thursday and Saturday.

Does the route become daily in winter?

Yes, but not immediately. STARLUX lists three weekly flights from October 27 to November 28, then daily JX318 and JX319 service from December 1, 2026 to March 27, 2027.

What is the time difference between Taichung and Sapporo?

Sapporo is one hour ahead of Taichung. The timetable already uses local time at each airport, so do not add another hour to the displayed arrival.

Is CTS the main airport for Sapporo?

CTS is New Chitose Airport, the main international gateway serving Sapporo. The JR station is inside the airport terminal building on B1.

How much baggage is included on STARLUX economy fares?

Economy includes one 7 kg cabin bag. The current checked allowance is one 23 kg piece on Limited and short-haul Saving fares, and two 23 kg pieces on Basic and Full. Always use the allowance printed on the issued ticket.

Can I check in online for JX318 or JX319?

Eligible passengers can normally check in online from 48 hours until one hour before departure. Checked baggage still has to reach the airport counter by the applicable cutoff.

Should I use Visit Japan Web before landing at New Chitose?

Japan's official service lets travelers complete immigration and customs arrival procedures online. Use it when eligible, but separately confirm passport and visa requirements for each traveler.

What should I know about the airport train to Sapporo?

JR trains run directly from the airport station to Sapporo in about 30 minutes. Buses can suit some hotel locations, while travelers continuing toward Otaru or Niseko should check the train destination and required transfer.

Will STARLUX check my bag through on a separate ticket?

Do not plan on it. STARLUX says bags must be collected and rechecked when the onward itinerary is on a separate ticket. Leave time for immigration, baggage reclaim, check-in and security.

Before booking

• Search the exact date because the operating days change twice.
• Confirm JX318 or JX319 and use the local airport time.
• Check for an unserved gap between the published schedule blocks.
• Read the baggage line on the issued ticket.
• Arrange special assistance before travel when needed.
• Complete the correct entry procedures for the passport being used.
• Leave a winter-weather buffer for Hokkaido ground transport.
• Keep separate flights on one ticket when practical.
• Save the itinerary, first-night address and transfer plan offline.
• Recheck flight status and JR service before leaving for the airport.

Verification notes for this guide

STARLUX's July 1 announcement supports the October 2 launch, first timetable and flight numbers. The airline's August 31 winter notice supports the later three-weekly and daily schedules. Its fare, carry-on, check-in and interline pages support the passenger rules.

New Chitose Airport and JR Hokkaido support the rail guidance. Japan's Digital Agency and Taiwan's official arrival-card service are the primary arrival-procedure sources. Public traveler discussions were used to choose questions about immigration time, baggage through-checking, self-connections, rail disruption and onward transfers; they were not used as authority for airline policy or entry rules.

We will update this guide if STARLUX changes the timetable, frequency, baggage or check-in rules, or if the route's operating status changes.
