How to Get the Cheapest Flights from Singapore in 2026: What's Actually Changed and What Works
A 2026 guide to finding cheap flights from Singapore, which booking tactics still work, how airline pricing has shifted, and where cashback applies on flight bookings.
Updated: October 2026.
If you are booking in the next 30 days (Oct 5 to Nov 4, 2026), you are inside the 6 to 10 week window for December school-holiday flights to Japan, Korea and Australia, and inside the 3 to 6 week window for a short-haul break before mid-November, so this is the month to lock fares rather than wait for 11.11 on Wednesday 11 November. Cheap-flight advice ages badly: the "book 6 months ahead" rule that worked a decade ago now often leaves you paying more, especially on the budget routes most Singaporeans actually fly. The decision this article helps with is where to book once Skyscanner has surfaced the fare: Expedia, Trip.com, Agoda or the airline direct. Use ShopBack to compare those three OTAs on the same itinerary, then book on whichever is cheapest after cashback.
The verdict
For Singapore travellers in 2026, the most reliable method to find cheap flights is to use Skyscanner or Google Flights for price comparison, then book via an OTA through ShopBack before you pay. Book short-haul LCC flights (Scoot, AirAsia) 3-6 weeks out; medium-haul (Japan, Korea, Australia) 6-10 weeks out. The exceptions are school holiday periods (June, December) and major Singapore public holidays, where fares spike 30-60% and earlier booking (10-14 weeks) is necessary.

How Singapore flight pricing actually moves
The Flight Booking Window Rule for Singapore: LCC fares from Changi follow a U-shaped pricing curve, prices start moderate, drop to their lowest 3-8 weeks before departure, then spike sharply in the final 2 weeks. This window is shorter than most travellers expect. Booking 6+ months ahead on LCC routes rarely saves money, because early-release fares on routes like SIN-BKK or SIN-KUL are often not the cheapest inventory. The exception is full-service carriers (Singapore Airlines, Cathay Pacific) for premium economy and business class, where early booking captures limited promotional fares.
The second lever: fare sales from Scoot and AirAsia run in predictable cycles tied to Singaporean marketing events (National Day, Christmas), and typically open a 48-72 hour booking window for heavily discounted fares 2-5 months out.

Fares and booking windows by route
| Route | Typical LCC Fare (off-peak) | Sale Fare | Booking Window for Best Price |
|---|---|---|---|
| Singapore to Bangkok | S$80-S$140 return | S$50-S$80 return | 3-5 weeks ahead |
| Singapore to Kuala Lumpur | S$60-S$100 return | S$30-S$60 return | 2-4 weeks ahead |
| Singapore to Bali (Denpasar) | S$120-S$200 return | S$80-S$130 return | 4-6 weeks ahead |
| Singapore to Tokyo | S$350-S$550 return | S$260-S$350 return | 6-10 weeks ahead |
| Singapore to Sydney | S$500-S$800 return | S$380-S$500 return | 8-12 weeks ahead |
| Singapore to London | S$700-S$1,200 return | S$550-S$750 return | 10-16 weeks ahead (FSC) |
The numbers show that for short-haul routes, the difference between optimal booking timing and last-minute booking is S$40-S$100 per person, significant for a family of 4.
How do I get the best fare on Singapore to Bali flights?
To get the best fare on a Singapore to Bali flight, compare every airline on the route for your exact dates, fly midweek and outside Singapore school holidays, book about 4 to 6 weeks ahead for an off-peak trip (earlier for June and December), and compare the all-in price with bags before you pay. Then book the cheapest option through ShopBack. According to Singapore Airlines' route network, both Singapore Airlines and its low-cost arm Scoot fly from Changi to Denpasar (DPS), Bali's airport.
Who flies Singapore to Bali, and why the headline fare can mislead
Singapore Airlines' network page lists Denpasar (Bali) as served by both Singapore Airlines (SQ) and Scoot (TR), and fare searches usually show other low-cost and Indonesian carriers on the route too, with schedules that change by season. The cheapest headline fare is often a low-cost basic fare where checked bags and seat selection are priced separately. If you are packing a surfboard bag, a dive kit or a family's worth of luggage, a full-service fare that already includes checked baggage can end up close to, or below, a low-cost fare once bags are added. Compare the price for the trip you are actually taking, not the lowest number on the results page.
What is the cheapest month to fly from Singapore to Bali?
There is no single cheapest month that holds every year, because fares depend on airline sales, holidays and demand. As a general pattern, Singapore to Bali fares are usually highest in the June and year-end school holidays and around Singapore long weekends, and usually lower in off-peak months outside those periods. To see the actual price data for your trip, use the month or date-grid views on fare-comparison tools: Skyscanner lets you search a whole month or the cheapest month, and Google Flights has a date grid and price graph. Set your trip length (say four nights), scan the cheapest departure days, and book when a fare you are happy with appears rather than waiting for a perfect low.
Trip.com vs Traveloka vs Skyscanner for Singapore to Bali flights
These three do different jobs. Skyscanner is a comparison site: it searches airlines and booking sites, then sends you to one of them to book. Trip.com and Traveloka are booking sites where you pay for the ticket. Trip.com usually shows prices in SGD for Singapore users and sells flights, hotels and airport transfers, including flight and hotel bundles. Traveloka, which says it was founded in Indonesia in 2012, is a natural place to check Bali flights alongside Bali hotels and activities, and it runs its own sale events during the year. The fair way to compare is the same flight, same dates and same baggage on each site, checked on the same day.
On Trip.com, note this rule: Promo, coupon, or discount codes make your entire Trip.com order ineligible for Cashback.
Costs to budget before you land in Bali
According to the Love Bali site run under the Bali Provincial Government's tourist levy regulation, international tourists pay a levy of IDR 150,000, which you can pay online before you travel. According to Singapore's Ministry of Foreign Affairs, Singapore passport holders visiting Indonesia as tourists may enter for up to 30 days under a visa exemption, without applying for a visa in advance, and this visa-free stay cannot be extended. Check both pages again close to your trip, since entry rules can change at short notice.
Book your Bali flight through ShopBack
Save on your trip by booking flights, hotels and activities through ShopBack. Open ShopBack first, then go to Trip.com, Traveloka or Expedia and book in the same session. ShopBack lowers the effective price of flights, hotels and online orders after you pay. Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.
Check the live rate on each store's ShopBack page before you book.
Where to book for cashback
Use Skyscanner or Google Flights to benchmark, then book via an OTA through ShopBack before you pay. Note: Scoot is on ShopBack Singapore through the ShopBack app; check the rate and terms on the ShopBack Scoot page before you book. AirAsia Travel is on ShopBack; check the live rate on its ShopBack page. For full-service carriers, compare Expedia, Trip.com and Agoda on ShopBack.
| Scenario | Direct Airline | OTA + ShopBack | Reason |
|---|---|---|---|
| Scoot short-haul | ShopBack app or direct | Check the ShopBack Scoot page | Scoot is on ShopBack Singapore through the ShopBack app |
| AirAsia short-haul | Check both | Check ShopBack (AirAsia Travel listed) | AirAsia Travel is on ShopBack, verify current rate |
| Skyscanner search | Use to compare | Book the fare via an OTA on ShopBack | Skyscanner is a comparison tool, book on the store you pick |
| Singapore Airlines / Cathay | Check direct | Prefer OTA (Expedia/Agoda) | OTA cashback on high fares adds meaningful savings |
| Multi-city or complex itinerary | No | Yes (Expedia, Agoda) | OTAs handle routing better; check ShopBack for cashback availability |
| Sale fare within 48h window | Direct (fast) | If tracking works | Move fast on sale fares; OTA tracking can lag |
| Business/premium class | Direct or OTA | Yes + cashback | Cashback on high fares worth checking |
What this means for your next booking
ShopBack lists several flight-related stores including Expedia, Agoda, Trip.com and AirAsia Travel. Cashback rates on all of these change regularly, so check the live rate on each store's ShopBack page before booking. Cashback is worked out on the eligible fare, so a high-value full-service fare is where it counts most.
In practice, this means: before booking any flight, check if ShopBack lists the OTA or airline you're booking through. Scoot is on ShopBack Singapore through the ShopBack app; check the rate and terms on the ShopBack Scoot page before you book. For SIA, Cathay, and most full-service carriers, booking via Expedia or Agoda on ShopBack is worth checking.
A typical trade-off: booking a SIN-TYO return on SQ directly for S$750 vs booking via Expedia on ShopBack at a similar fare with cashback coming back after the trip is confirmed. Check both, the net price after cashback often makes the OTA route cheaper even if the headline fare is marginally higher.

When this does NOT apply
- School holiday peak travel (June, December): Fares during Singapore school holidays are 30-60% higher and the optimal booking window shifts earlier to 10-16 weeks. Cashback helps but won't offset the peak premium.
- LCC promotional fares requiring instant booking: Scoot and AirAsia flash sales sometimes require immediate checkout. Scoot is on ShopBack Singapore through the ShopBack app; check the rate and terms on the ShopBack Scoot page before you book. For AirAsia flash fares, OTA cashback tracking may not activate in time, book direct on those specific fares.
- Mileage redemption flights: Cashback is generally not applicable to award tickets, but verify with ShopBack's terms if booking through an OTA, as the rules depend on how the booking is processed.
- Group bookings above 9 passengers: Airlines' group booking desks offer negotiated rates outside standard OTA inventory. Whether OTA cashback applies in these cases depends on how the booking is structured, check with ShopBack.
- Connecting flights with different carriers: Split ticketing with two separate airlines (e.g. Scoot to KUL, then AirAsia to Manila) carries risk if the first leg delays. Each booking is separate, cashback eligibility depends on each carrier or OTA individually.

Frequently asked questions
When is the cheapest time to book flights from Singapore in 2026?
For short-haul (Bangkok, KL, Bali), book 3-6 weeks ahead for the best fares. For medium-haul (Japan, Korea, Australia), book 6-10 weeks ahead. Booking earlier than 10 weeks rarely saves money on LCC routes from Singapore.
Is Skyscanner still the best way to find cheap flights from Singapore?
Yes, Skyscanner remains the most comprehensive fare aggregator for Singapore-origin flights in 2026, but always verify the price directly on the airline's or OTA's site before booking, as Skyscanner results can lag real-time pricing.

Yes, ShopBack lists several flight-related stores including Expedia, Agoda, Trip.com and AirAsia Travel. Scoot is on ShopBack Singapore through the ShopBack app; check the rate and terms on the ShopBack Scoot page before you book.

Rates differ by partner and change monthly; check the current published rate on each merchant page before booking.
What is the cheapest way to book a Singapore to Tokyo return flight?
For an off-peak SIN to Tokyo return, benchmark fares on Skyscanner or Google Flights across dates and airports, then book through the winning OTA (Expedia, Agoda or Trip.com) via ShopBack. Scoot is on ShopBack Singapore through the ShopBack app; check the rate and terms on the ShopBack Scoot page before you book. Cashback tracks on eligible fare value at the current published rate.
Can I earn ShopBack Cashback and airline miles on the same booking?
Cashback via ShopBack applies on the cash fare component and typically does not affect airline mile accrual on the same booking, so KrisFlyer, Asia Miles, Enrich, AirAsia BigPoints and equivalent miles usually still accrue, though miles eligibility varies by carrier and fare class (some deep-discount fares exclude miles). Go through ShopBack to Expedia, Trip.com or Agoda before you pay and verify tracking after checkout.
How much cashback can I earn on a typical family flight booking?
Cashback depends on the live rate on the store's ShopBack page and the eligible fare value; ShopBack does not guarantee a flat rate across flights. Bigger family bookings through Expedia, Agoda or Trip.com earn on a larger fare value, so check the live rate on the store's ShopBack page before booking.
When is the best window for flight deals from Singapore?
Scoot and AirAsia flash sales typically open 2 to 5 months out, targeting National Day, Christmas and Chinese New Year travel. OTAs (Expedia, Agoda, Trip.com) run tie-in windows around 6.6, 9.9, 11.11, 12.12 and Payday Weekend. Route through AirAsia Travel, Expedia or Trip.com during these windows to earn cashback on the sale fare at the current published rate.
Is it cheaper to book a flight-only or a flight-plus-hotel package?
For fixed-date city breaks (Tokyo, Osaka, Seoul, Bangkok), flight-plus-hotel packages on Expedia and Trip.com typically beat booking flight and hotel separately by 5 to 15 percent for the same room and fare class. For open-jaw or multi-city itineraries, a flight found on Skyscanner and booked through an OTA, plus a separate hotel via Agoda usually wins. Route through ShopBack on whichever approach is cheaper.
Should I book my December flight from Singapore on Expedia, Trip.com or Agoda, or direct with the airline?
Book direct with Scoot or AirAsia for a short-haul low-cost fare, because their own sites rarely lose to an OTA and changes are simpler. Scoot is on ShopBack Singapore through the ShopBack app; check the rate and terms on the ShopBack Scoot page before you book. For a full-service fare on Singapore Airlines or Cathay Pacific to Tokyo, Sydney or London, price the same flight on Expedia, Trip.com and Agoda, since OTA cashback on a S$750 to S$1,200 ticket is where the saving is meaningful. Trip.com tends to win on Asian carriers and packages, Expedia on multi-city and flight-plus-hotel bundles, Agoda when you are adding a hotel in the same basket. Use ShopBack to compare Expedia, Trip.com and Agoda on the day, then book from whichever is cheapest after cashback.
How do I get the best fare on Singapore to Bali flights?
Compare every airline on the route for your exact dates, fly midweek and outside Singapore school holidays, book about 4 to 6 weeks ahead for an off-peak trip (earlier for June and December), and compare the all-in price including bags. According to Singapore Airlines' route network, both Singapore Airlines and Scoot fly from Changi to Denpasar (DPS). Then book the cheapest option through ShopBack, which lowers the effective price of your flight after you pay.
What is the cheapest month to fly from Singapore to Bali?
No single month is cheapest every year, because fares depend on airline sales, holidays and demand. Fares are usually highest in the June and year-end school holidays and around long weekends, and usually lower in off-peak months. Use the whole-month view on Skyscanner or the date grid and price graph on Google Flights to see the cheapest days for your trip length.
Should I book Singapore to Bali flights on Trip.com, Traveloka or Skyscanner?
Skyscanner is a comparison site that sends you to an airline or booking site, while Trip.com and Traveloka are booking sites where you pay for the ticket. Trip.com usually shows SGD prices and sells flight and hotel bundles, and Traveloka, which says it was founded in Indonesia in 2012, is a natural place to check Bali flights with Bali hotels and activities. Compare the same flight, dates and baggage on each, and note that promo, coupon, or discount codes make your entire Trip.com order ineligible for Cashback.
Do Singaporeans need a visa or pay a tourist levy to visit Bali?
According to Singapore's Ministry of Foreign Affairs, Singapore passport holders visiting Indonesia as tourists may enter for up to 30 days under a visa exemption, and this stay cannot be extended. According to the Love Bali site run under the Bali Provincial Government's regulation, international tourists pay a levy of IDR 150,000. Check both official pages close to your trip, as rules can change at short notice.
Key takeaways
- If booking short-haul LCC flights, the sweet spot is 3-6 weeks before departure, not 3 months ahead
- If booking medium-haul (Japan, Australia), 6-10 weeks out captures the best fares on most routes
- If flying during Singapore school holidays or public holidays, book 10-16 weeks ahead, fares are 30-60% higher and don't come down
- Always go through ShopBack before booking, Expedia, Agoda, Trip.com and AirAsia Travel are listed stores; Scoot is on ShopBack Singapore through the ShopBack app, so check the ShopBack Scoot page before you book
