Most "cheapest month to fly to Singapore" articles are guesswork. We went looking for a citable source for it and could not find one — Australia's official international airline statistics run months behind, and fare-comparison sites do not publish their method. So instead of inventing a number, here is what genuinely moves the price of a Singapore ticket right now, and what you will actually pay once you land.

Two fee changes are landing on Singapore tickets

Every passenger departing Changi pays a set of fixed charges built into the ticket. For the year from 1 April 2026 they are:

Changi has already published the next step: from 1 April 2027 that total rises to S$70.20. If you are only transiting rather than starting your journey in Singapore, you pay S$15.00 instead.

Separately, Singapore is introducing a sustainable aviation fuel levy. It applies to tickets sold from 1 October 2026, for flights departing Singapore from 1 January 2027. Australia sits in Band II, so the charge is S$2.80 in economy and S$11.20 in business or first. The aviation authority requires it to appear as its own line in the fare breakdown, so you will see it itemised rather than buried.

Neither is large on its own. Together they mean a Singapore-departing leg in 2027 carries roughly S$8 more in fixed charges than the same leg does today — worth knowing if you are comparing a ticket now against one you held off booking.

Sydney is getting more Singapore Airlines capacity, not less

This is the genuine news for Australian travellers. Singapore Airlines is launching a daily Singapore–Western Sydney International service from 23 November 2026, flights SQ201 and SQ202, on an A350-900 with 303 seats. Added to four daily services into Sydney Kingsford Smith, that makes five Singapore Airlines flights a day into Sydney.

Cairns also picked up an extra weekly service between 7 July and 22 September 2026. No frequency changes were announced for Melbourne, Brisbane, Perth, Adelaide or Darwin.

More seats on a route generally means more fare competition, so the Sydney market is one of the few Australia–Asia routes where the supply picture is improving rather than tightening.

A correction worth making: Jetstar still flies to Singapore

Jetstar Asia — the Singapore-based subsidiary — closed on 31 July 2025, and it is regularly misreported as Jetstar pulling out of the Singapore market. It is not the same thing. Qantas Group stated plainly at the time that all Jetstar Airways international services in and out of Australia were unchanged, including flights from Australia to Singapore. If a comparison site shows you a Jetstar fare, it is real.

Is there a quiet season? Barely

Changi publishes its monthly passenger numbers, and across 2026 they sit in a narrow band — from about 5.54 million in February to 6.10 million in March. February was the quietest month and March the busiest, but the spread is only around 10%.

That is airport-wide traffic, not Australian fares, and it is a weak signal. The honest conclusion is that Singapore does not have a pronounced cheap season the way a beach destination does. It is a year-round hub. Set a fare alert on your dates rather than trying to time a month.

For context, Changi handled close to 70 million passengers in 2025, a record, and added 13 new destinations — the most new city links it has ever opened in one year.

Before you fly: the arrival card is free

All travellers must submit the SG Arrival Card with electronic health declaration before arriving. Two things matter:

Once you land, Changi now runs passport-free biometric clearance. Since May 2026 arriving foreign visitors clear immigration on face and iris alone, without presenting a passport at the lane. You still need the passport with you and you still submit the arrival card — the biometrics replace showing the document, not carrying it.

What Singapore costs once you are there

Getting into the city. Changi to Marina Bay takes about 50 minutes on the MRT. A standard adult tap costs somewhere between S$1.28 and S$2.57 depending on distance. A taxi is S$25–S$45 and roughly 30 minutes, plus an airport surcharge of S$8 between 5pm and midnight or S$6 at other times. A booked private transfer through the airport's own concierge is S$70 for four seats or S$75 for six.

Paying for transport. Foreign contactless Visa, Mastercard and Amex all work on buses and trains, including Apple Pay and Google Pay. There is a catch: foreign Visa and Mastercard taps attract a S$0.60 per-day admin fee, on top of whatever your bank charges for currency conversion. Over a week that is about one extra short trip's worth.

The Singapore Tourist Pass costs S$17 for one day, S$24 for two and S$29 for three. Do the maths before buying: at S$1.28–S$2.57 a ride, a one-day pass needs roughly seven or more trips in a day to beat simply tapping. Most visitors are better off with a contactless tap or a S$10 EZ-Link card.

Tax. Singapore's GST is 9%, and has been since 1 January 2024. Visitors aged 16 and over can claim it back on departure through the Tourist Refund Scheme if you spend at least S$100 including GST at a participating retailer. You may combine up to three same-day receipts from the same shop and GST registration number. Claims are made at eTRS kiosks at Changi or Seletar, where you scan your physical passport — so present the same passport when you buy.

Three costs people get caught by

Free things at the airport itself

If you have a long layover, Changi is unusually generous. The Butterfly Garden in Terminal 3 transit is free and open 24 hours. So is the movie theatre in Terminal 3 transit, closed only for maintenance on Thursdays from 11am to 4pm. The Free Singapore Tour is genuinely free for anyone with a 5.5 to 24 hour transit and bags checked through — four two-and-a-half-hour options, bookable up to 50 days ahead or at the booths in T2 and T3.

Jewel's Rain Vortex, the 40-metre indoor waterfall, is free to look at, running daily 10am to 10pm with a light and music show in the evening. One thing to know: Jewel is landside, so a transit passenger has to clear immigration to reach it. Canopy Park inside Jewel is ticketed at S$8.

The short version

There is no trustworthy "cheapest month" for Singapore — it is a year-round hub and the traffic data barely moves. What does change is fees: S$65.20 in fixed charges on a departing ticket today, S$70.20 from April 2027, plus a S$2.80 fuel levy on economy tickets sold from October 2026 for travel from January. Sydney gains a fifth daily Singapore Airlines service from 23 November 2026. Jetstar never left. Submit the free arrival card within three days of arriving, budget 9% GST, and remember the Gardens by the Bay conservatories cost visitors S$46 with no cheaper single-dome option.

Fees, fares and admission prices above were checked in September 2026 against Changi Airport Group, the Civil Aviation Authority of Singapore, Singapore's Land Transport Authority and SimplyGo, IRAS, Singapore Customs, ICA, Gardens by the Bay, NParks and Singapore Airlines.
