Volcanic ash from Mount Anak Krakatau shut Jakarta's Soekarno-Hatta airport and several other Indonesian airports over the weekend, and the knock-on effects are still being worked through on the Singapore to Jakarta route today.
> Quick view: On 8 September 2026, Singapore Airlines has retimed six Singapore to Jakarta flights and is adding eight relief flights on the route. Scoot cancelled six flights on 6 and 7 September with rebooking or a full refund offered, and lists nothing cancelled for 8 September. Both airlines call the situation fluid: check your flight status before leaving home.
What Singapore Airlines has changed today
SIA's advisory, first posted on 5 September and last updated on 8 September 2026 at 8.50am, lists these retimings. All times are local.
| Flight | Route | Original departure | New departure |
|---|---|---|---|
| SQ950 | Singapore to Jakarta | 6.20am | 1.10pm |
| SQ952 | Singapore to Jakarta | 7.40am | 1.40pm |
| SQ956 | Singapore to Jakarta | 9.05am | 7.30pm |
| SQ953 | Jakarta to Singapore | 8.05am | 2.50pm |
| SQ955 | Jakarta to Singapore | 9.25am | 3.35pm |
| SQ957 | Jakarta to Singapore | 11.00am | 9.25pm |
Note how far some of these move. SQ956 slides more than ten hours, from a morning departure to an evening one, and SQ957 goes from late morning to late night. If you are on either of those, a same-day connection or a hotel check-in on the other side is almost certainly no longer going to work as booked.
SIA says all other flights are currently operating as scheduled, and that eight additional relief flights between Singapore and Jakarta will be mounted on 8 September to move affected customers, subject to seat availability. It will progressively rebook affected customers onto the next available flight as the route resumes.
What Scoot cancelled
Scoot's separate advisory, last updated 6 September at 8.30pm, cancelled these as a precautionary measure:
- 6 September: TR272 (Singapore to Jakarta, 8.30pm) and TR273 (Jakarta to Singapore, 10.15pm)
- 7 September: TR274 (Singapore to Jakarta, 7.50am), TR275 (Jakarta to Singapore, 9.35am), TR276 (Singapore to Jakarta, 10.00am) and TR277 (Jakarta to Singapore, 11.55am)
Scoot says it contacted affected customers using the details on their booking, and gave them the option to rebook, or request a full refund if they no longer wish to travel. Nothing is listed as cancelled for 8 September, but Scoot also says it will keep adjusting its schedule as needed.
What to actually do before you go to the airport
- Check the airline's flight status page, not the app notification you got yesterday and not this article. Schedules on this route have moved more than once a day since Friday.
- Update your contact number under Manage Booking, or subscribe to the airline's flight status notifications. Both airlines rebook by contacting you, which only works if the number on the booking is one you still answer.
- Rebooking with SIA: call +65 6351 0013 from Singapore, or use the chat function in the SIA help centre.
- Booked through an agent or a partner airline? Go back to them. Both SIA and Scoot say bookings made that way have to be changed by the agent or the purchasing airline, and calling the operating airline will just send you back around the loop.
- Do not rush to buy travel insurance now expecting it to cover this. See below.
The insurance point, and it is the one most people get wrong
Singapore travel insurers generally exclude a known event: something that has already happened, or has already been reported by the media or announced by the authorities, before you bought the policy. This eruption has been public news since 5 September 2026. A policy bought after that date is unlikely to pay out for a cancellation or delay caused by it.
If your policy was already in force before the eruption, natural disaster is commonly a named cause under trip cancellation, curtailment and travel delay benefits. But the limits, the minimum delay hours and the documents you must produce differ by insurer and by plan tier, so read your own wording, keep the airline's written notice of the cancellation or retiming, and speak to your insurer directly. General information only, not financial or insurance advice.
Why this matters beyond Jakarta
Soekarno-Hatta is one of Southeast Asia's busiest airports, and the weekend closures affected several Indonesian airports at once, stranding hundreds of thousands of travellers on regional routes. Aircraft and crew that were stuck out of position take days to redistribute even after airports reopen, which is why a flight can be retimed by ten hours on a day when the ash has already cleared. If you are flying anywhere in Indonesia this week, treat the published schedule as provisional.
