Singapore's Changi Airport is one of the busiest aviation hubs in Asia, and it is served by a strong lineup of low-cost carriers that connect the city-state to destinations across Southeast Asia, South Asia, Northeast Asia, and beyond. Whether you are hopping across the causeway to Kuala Lumpur, heading to Bali for the weekend, or making a longer journey to Bangkok or Tokyo, there is a budget airline to get you there without breaking the bank. This guide covers the top budget airlines operating out of Singapore, with details on their routes, baggage policies, and tips to get the best fares.

AirAsia is arguably the most recognisable low-cost carrier in Southeast Asia, and its Singapore operations out of Changi Terminal 4 serve as a key hub for travellers heading into the region. The airline connects Singapore to Kuala Lumpur, Kota Kinabalu, Kuching, Penang, Johor Bahru, and dozens of other destinations across the AirAsia network. Fares can dip as low as SGD 10 to SGD 20 during promotional sales, making it one of the most affordable options for short-haul travel. Cabin baggage is limited to 7 kg and checked baggage is sold separately, so it pays to bundle your bags when booking to get the best rate.

AirAsia's BIG Loyalty programme lets frequent flyers earn and redeem points across flights, hotels, and car rentals. The airline also regularly runs flash sales through its app, where seats to popular routes like Singapore-Bali or Singapore-Bangkok disappear fast. If you fly AirAsia often, setting fare alerts is a smart habit. Booking early, typically 8 to 12 weeks ahead for peak travel periods, tends to yield the lowest base fares.

Scoot is Singapore Airlines' low-cost subsidiary and operates out of Changi Terminal 1 and Terminal 2. It covers an impressively wide network that includes Bangkok, Tokyo, Osaka, Seoul, Taipei, Perth, Sydney, Athens, and Honolulu, making it one of the few budget carriers that genuinely bridges short-haul and ultra-long-haul travel. Scoot's ScootPlus cabin offers extra legroom and a meal for travellers who want a little more comfort without paying full-service prices. Base fares on short routes to Bangkok or Kuala Lumpur regularly come in under SGD 50, while longer routes to Australia or Japan can be found under SGD 200 during sales.

Checked baggage starts from 20 kg and is purchased as an add-on. Scoot operates a mixed fleet of Boeing 787 Dreamliners and Boeing 737s, which means long-haul flights on the Dreamliner offer a noticeably better cabin environment despite the budget pricing. The ScootHub loyalty tier system rewards repeat travellers with priority boarding and other perks. For travellers based in Singapore looking to explore Northeast Asia or Australia on a budget, Scoot is often the first place to check.

Jetstar Asia is the Singapore-based arm of the Jetstar Group and operates out of Changi Terminal 1. It focuses primarily on short to medium-haul routes across Southeast and Northeast Asia, including Bangkok, Ho Chi Minh City, Hanoi, Manila, Osaka, Tokyo, and Hong Kong. The airline is a good option for travellers who want the low-cost price point with slightly more predictability than some smaller carriers. Fares to Bangkok or Ho Chi Minh City are frequently available below SGD 80 return during promotional periods.

Jetstar Asia includes 7 kg cabin baggage in all fares, and checked baggage bundles start from 15 kg. The airline often bundles meals, checked bags, and seat selection into its ""Starter Plus"" or ""Max"" bundles, which can work out cheaper than adding each item individually. Jetstar Asia is also part of the Qantas Frequent Flyer programme, so Australian travellers or Qantas loyalists can earn points on these flights. Its punctuality record at Changi has generally been solid, which is an underrated factor when connecting to onward travel.

Cebu Pacific is the Philippines' largest low-cost carrier and connects Singapore to Manila, Cebu, Clark, and a handful of secondary Philippine destinations. If you are planning a trip to the Philippines and want to avoid full-service prices, Cebu Pacific is frequently the most competitively priced option on the Singapore-Manila route. The airline is well known for its ""piso fare"" sales, where seats are occasionally released at near-zero base prices, although these are snapped up very quickly. A typical Singapore to Manila one-way fare outside of sales sits in the SGD 60 to SGD 130 range depending on season.

Cabin baggage allowance is 7 kg and checked baggage is a paid add-on starting from 20 kg. The airline operates out of Changi Terminal 2 and has expanded its Singapore routes steadily over the past few years. Cebu Pacific's Juan for Fun seat sale programme runs throughout the year and is worth subscribing to if the Philippines is a regular destination for you. For multi-island itineraries within the Philippines, Cebu Pacific's domestic connectivity from Manila or Cebu adds real value to the fare.

Batik Air Malaysia (formerly known as Malindo Air) operates from Changi and serves routes to Kuala Lumpur, Penang, Langkawi, Kota Kinabalu, and several secondary Malaysian cities. What makes Batik Air stand out in the budget segment is that it includes checked baggage of up to 30 kg and an in-flight meal in its standard Economy fares — a full-service-level offering at closer to low-cost prices. This makes it particularly attractive for travellers carrying more luggage or families who want a more comfortable short-haul experience without upgrading to Malaysia Airlines or Singapore Airlines.

The Singapore to Kuala Lumpur route via Batik Air is one of the more popular short-haul options for travellers who prefer flying over the bus or train crossing. The airline operates a mix of Airbus A320 and Boeing 737 aircraft. Booking directly through the Batik Air website or via platforms like Traveloka often surfaces better fares than third-party aggregators. If you are travelling with children or excess baggage, the bundled allowance makes Batik Air a genuinely cost-effective choice.

IndiGo is India's largest airline by market share and operates budget-friendly flights between Singapore and several Indian cities including Chennai, Kolkata, Mumbai, and Hyderabad. For travellers with South Asian itineraries, IndiGo offers competitive pricing and a straightforward no-frills experience. Fares on the Singapore to Chennai corridor in particular are frequently lower than those offered by full-service carriers, and the flight time of under four hours makes this a very manageable journey.

IndiGo's cabin baggage allowance is 7 kg and checked baggage is charged separately, starting at 15 kg for most Economy fares. The airline has a strong on-time performance record, which is a meaningful consideration for connecting travel. IndiGo operates from Changi Terminal 1 and typically runs multiple flights per day on its busiest routes. For the Singapore-based Indian community or travellers making business trips to Chennai or Hyderabad, IndiGo is often the most practical and affordable option.

Vietjet Air connects Singapore to Ho Chi Minh City, Hanoi, Da Nang, and Nha Trang, covering the main tourist and business corridors between Singapore and Vietnam. The airline is known for aggressive base fare pricing, with promotional one-way fares on the Singapore to Ho Chi Minh City route occasionally dipping below SGD 30. Vietjet's SkyBoss and SkyBoss Business options add meals, extra baggage, and seat selection for travellers who want a bit more without switching to a full-service carrier.

Standard Economy fares on Vietjet come with 7 kg cabin baggage and no checked baggage included, so adding a 20 kg hold bag is recommended if you are packing for more than a weekend trip. The airline has grown rapidly in the Singapore market and its frequency on the Singapore to Ho Chi Minh City route means flexible scheduling. Vietjet also runs periodic ""zero-fare"" campaigns that are worth monitoring if Vietnam is on your travel radar for 2026.

Thai Lion Air is the Thai affiliate of the Lion Air Group and serves routes between Singapore and Bangkok's Don Mueang Airport, which is the budget airline hub for the Thai capital. Don Mueang is well-connected by public transport to central Bangkok, making Thai Lion Air a practical option despite operating out of the city's secondary airport. Base fares on the Singapore to Bangkok route via Thai Lion Air are often among the lowest available, particularly during off-peak periods and promotional sales.

The airline includes 7 kg cabin baggage in its basic fares, with checked baggage purchased as an add-on. Thai Lion Air operates Airbus A330 aircraft on this route, which offers a larger and more comfortable cabin than many narrow-body budget options for the same price point. For travellers who prioritise getting to Bangkok cheaply and do not mind the slightly longer transfer from Don Mueang to the city centre compared to Suvarnabhumi, Thai Lion Air delivers strong value.

Booking at the right time makes a significant difference when flying budget out of Singapore. Most low-cost carriers release their cheapest seats 8 to 12 weeks ahead of departure for leisure travel, and prices tend to climb as the date approaches. Subscribing to airline newsletters and fare alert services means you get notified the moment a sale goes live. Tuesday and Wednesday mornings are traditionally when airlines post new fare drops for the coming weeks.

Travelling light is one of the most effective ways to keep total costs down. Many budget airlines offer very low base fares but charge substantially for checked baggage, seat selection, and meals when added individually. Bundling these at the time of booking is almost always cheaper than adding them later. If you are travelling as a couple or group, coordinating baggage to avoid duplicate 20 kg check-in fees can save a meaningful amount on short-haul routes.

Consider flexible dates when searching — shifting departure by even one or two days can sometimes halve the fare on competitive routes. Budget carriers flying out of Changi also offer airport transfer connectivity from key neighbourhoods in Singapore, and booking your ground transport alongside your flight on Traveloka keeps everything in one place. For trips that extend beyond the city into drives across Malaysia or Indonesia, having car rental sorted ahead of time adds flexibility to your journey.
