Top 10 Cheapest Airlines In Singapore 2026

Finding the cheapest airlines in Singapore in 2026 comes down to one hub and ten carriers that keep fares out of Changi and Seletar low. According to Trip.com's 2026 fare rankings, AirAsia holds the title of the world's cheapest airline, and it leads our list of budget carriers serving Singapore. We built this ranking from Trip.com and momondo fare data, the Skytrax World Airline Awards 2026 low-cost rankings, and the route networks operating out of Singapore Changi Airport.

Fares across the region have stayed aggressive. Competition on the Singapore-Kuala Lumpur, Singapore-Bangkok and Singapore-Manila corridors keeps one-way prices under S$100 on many dates. The ten carriers below cover everything from sub-S$60 hops to Malaysia to the cheapest direct routes to India and China.

How We Ranked These

We weighed four factors: typical all-in fares from Singapore in 2026, route depth out of Changi and Seletar, promotional pricing frequency, and value once baggage and meal add-ons are counted. Fare data came from Trip.com and momondo searches for 2026 travel dates, cross-checked against Skytrax low-cost carrier rankings. Carriers with a Singapore base and high frequency on popular ASEAN routes scored higher than those with limited destinations, even where base fares were comparable.

The List Of The Top 10 Cheapest Airlines in Singapore 2026:

1. AirAsia

AirAsia tops Trip.com's 2026 global rankings as the world's cheapest airline, and its grip on Singapore's budget market is hard to overstate. The Malaysian group runs an extensive short-haul network across ASEAN through hubs in Kuala Lumpur, Johor Bahru and Kota Kinabalu, feeding constant capacity into Changi.

Fares from Singapore to Kuala Lumpur, Kuching and Penang often land under S$100 one-way, and promotional sales push them lower still. The no-frills model means baggage, seat selection and meals cost extra, but the base fare stays lean.

What separates AirAsia from the pack is consistency. Other carriers run deeper sales, but none match AirAsia's combination of frequency and low pricing on the highest-volume routes out of Singapore. For travellers heading to Malaysia, Indonesia, Thailand or Vietnam on a tight budget, it is the default starting point.

2. Scoot

Scoot, Singapore Airlines' low-cost subsidiary, is based at Changi and serves more than 60 destinations across Asia, Australia and Europe. That local base gives it the deepest inventory of budget fares departing from Singapore, including medium and long-haul routes that most budget carriers avoid.

One-way fares to Bangkok and Jakarta typically start around S$60 to S$90. The real differentiator is range: Scoot flies to Tokyo, Seoul and Berlin at a fraction of full-service prices. Its ScootPlus cabin and Stretch legroom option undercut premium economy on legacy carriers by wide margins.

Skytrax named Scoot the World's Best Long-Haul Low-Cost Airline in 2025, a recognition that reflects both its network and its product consistency. For Singapore-based travellers who want budget pricing without transiting through a foreign hub, it is the most convenient option on this list.

3. Jetstar Asia

Jetstar Asia is headquartered in Singapore and forms part of Australia's Qantas Group. Its dense short-haul network covers Malaysia, Thailand, Indonesia, Vietnam and Japan, with fares to Kuala Lumpur, Phuket and Bangkok frequently falling between S$55 and S$85 one-way on 2026 promotional pricing.

The carrier's Friday Frenzy and Club Jetstar sales are among the most aggressive in the market, and its Singapore base means high frequency on popular ASEAN routes. On key corridors, Jetstar Asia prices sit within a few dollars of AirAsia.

Where it loses ground is long-haul reach. Jetstar Asia's network is regional, so travellers heading beyond Asia will need to connect through another carrier. On pure short-haul value from Changi, though, it is a genuine contender for the top spot.

4. Cebu Pacific

Cebu Pacific is the Philippines' largest low-cost carrier, and its signature Piso Fare sales, with base fares from one peso before taxes and fees, make it one of the cheapest ways to reach the Philippines from Singapore. Direct routes connect Changi to Manila, Cebu and Clark using a high-density mix of ATR turboprops and A320 and A330 jets.

Typical Singapore-Manila fares run from around S$90 to S$130 one-way. The base-fare promotions are among the most dramatic in the region, though taxes, baggage and seat fees push the all-in price above AirAsia or Scoot on some dates.

The airline also links Singapore to secondary Philippine islands that full-service carriers skip, which matters for travellers heading to Cebu, Bohol or Palawan. For Philippine routes specifically, no carrier on this list comes close on promotional pricing.

5. VietJet Air

VietJet has turned Vietnam into one of the cheapest international destinations from Singapore. The carrier flies direct from Changi to Ho Chi Minh City and Hanoi, with fares typically from S$80 to S$120 one-way and frequent 0 đồng promotional fares that sell out fast.

Founded in 2011, VietJet has expanded regional connectivity at speed and now operates a growing fleet of A320, A321 and A330 aircraft. Its flash sales are worth watching if your travel dates are flexible, since the deepest discounts appear with little notice.

Route depth from Singapore is thinner than the top four carriers, which keeps VietJet in fifth place. On Vietnam routes, though, it consistently beats full-service competitors by a wide margin, and the direct flights to Ho Chi Minh City remain the fastest budget option to Vietnam's commercial capital.

6. Batik Air (Malaysia)

Batik Air Malaysia, part of Indonesia's Lion Group, takes a different approach to the budget game. Fares from Singapore to Kuala Lumpur often run from S$70 to S$100 one-way, and many of those fares bundle 20kg of checked baggage and meals.

Once add-ons are counted, Batik Air's effective value can beat the no-frills carriers on the same route. A traveller who would pay S$30 to S$50 for baggage and food on AirAsia may find Batik's all-in price lower.

The airline has expanded Singapore-KL frequencies to compete directly with AirAsia, and it also serves Penang and other Malaysian cities. Its network is smaller and frequencies lower than the top-ranked carriers, which is why it sits mid-table rather than higher.

7. Firefly

Firefly, a subsidiary of Malaysia Aviation Group, runs turboprop ATR 72 flights from Singapore's Seletar Airport to Malaysian secondary cities including Ipoh, Penang and Kuala Terengganu. Fares typically range from S$80 to S$120 one-way, with baggage allowances included.

The Seletar base is Firefly's quiet advantage. The airport is smaller and faster to clear than Changi, and the routes it serves are largely ones legacy carriers don't fly. For travellers heading to Ipoh or Kuala Terengganu, Firefly often provides the only direct option.

Limited destinations and a turboprop-only fleet cap its ranking. But on convenience and value for Malaysian secondary cities, nothing else on this list competes.

8. Thai Lion Air

Thai Lion Air, another Lion Group subsidiary, operates budget flights from Singapore to Bangkok's Don Mueang airport and other Thai points. Fares run from around S$90 to S$130 one-way, undercutting Thai Airways and Singapore Airlines by 40 to 60 percent on comparable routes.

The carrier uses a standardized Boeing 737 fleet with paid add-ons, keeping costs predictable. On the busy Singapore-Thailand corridor it competes directly with AirAsia and Scoot, though with fewer frequencies.

Brand reliability is the sticking point. Thai Lion Air has less name recognition in Singapore than the top-ranked carriers, and schedule changes are more common. For price-sensitive travellers who can absorb some flexibility, the savings are real.

9. IndiGo

IndiGo is India's largest airline and one of the world's biggest low-cost carriers by fleet, with more than 350 aircraft. It flies direct from Singapore to Chennai, Bengaluru and Delhi using A320neo and A321neo aircraft, with fares from around S$150 to S$220 one-way.

Those fares are higher in absolute terms than the ASEAN short-haul options, simply because the distances are longer. Against full-service carriers on the same India routes, IndiGo undercuts significantly, and its scale supports frequent schedules.

For travellers heading to India, it is the cheapest direct option from Singapore. The lack of short-haul routes keeps it out of the top half of this list.

10. Spring Airlines

Spring Airlines, founded in 2005 as China's first low-cost carrier, connects Singapore to Shanghai and other Chinese cities. Fares run from around S$180 to S$250 one-way, well below full-service Chinese and Singaporean carriers on the same routes.

The airline operates a single-class A320 fleet with paid extras, a model that has made it China's largest budget carrier by passengers. For direct budget travel to China from Singapore, it is the only real option.

Route options remain limited compared with the ASEAN-focused carriers, and the higher absolute fares place it last among the ten. On China routes, however, the savings against legacy carriers are substantial enough to justify the ranking.

AirAsia's combination of frequency and low fares keeps it at the top of the cheapest airlines in Singapore for 2026, with Scoot and Jetstar Asia close behind on the strength of their Changi bases. The rest of the list covers the routes where budget competition is thinner, from Philippine island hops on Cebu Pacific to direct China flights on Spring Airlines.
