Changi Airport connects Singapore to more low-cost carriers than almost any other Southeast Asian hub, covering everything from a 90-minute hop to Kuala Lumpur to long-haul routes stretching toward Australia and Japan. Eight airlines below cover the range, sorted by the regions they serve best.

Comparing fares across these carriers gets easier once your travel dates are locked in, so start by checking flights out of Singapore.

Arguably the most recognisable low-cost carrier in Southeast Asia, AirAsia connects Singapore to Kuala Lumpur, Kota Kinabalu, Kuching, Penang, and Johor Bahru on a near-constant rotation of promotional fares. Prices for short regional hops occasionally drop to the SGD 10 to 20 range during flash sales, though standard fares run considerably higher. The base fare includes a 7kg cabin bag only, with checked baggage sold separately, and the BIG Loyalty programme rewards frequent flyers with points redeemable across the airline's network.

Singapore Airlines' low-cost subsidiary operates out of both Terminal 1 and Terminal 2, running an unusually wide route map for a budget carrier that stretches from Bangkok and Tokyo to Perth, Sydney, Athens, and Honolulu. Short regional fares often sit under SGD 50, while long-haul routes can still come in under SGD 200 during sale periods. Its fleet of Boeing 787 Dreamliners on longer routes gives a noticeably more comfortable long-haul experience than most budget carriers offer.

The Philippines' largest budget carrier flies from Singapore to Manila, Cebu, Clark, and a handful of secondary Philippine cities, with typical one-way fares landing between SGD 60 and 130. Its recurring Juan for Fun seat sale periodically drops fares well below that range for travellers willing to book opportunistically. Baggage follows the standard budget model: a 7kg cabin allowance included, with 20kg checked bags available as a paid add-on.

Indonesia's largest low-cost carrier connects Singapore directly to Jakarta's Soekarno-Hatta Airport, with onward domestic connections across dozens of Indonesian cities from there. It's a practical pick for travellers heading beyond Bali or Jakarta into Indonesia's wider archipelago, since few other Singapore-based budget carriers offer that depth of domestic Indonesian coverage. Fares on the Singapore-Jakarta route are competitive with the other short-haul options on this list, particularly when booked outside peak travel weeks.

A hotel booked alongside your flight often works out cheaper than booking each separately, especially for a short layover trip.

Formerly known as Malindo Air, this carrier serves Kuala Lumpur, Penang, Langkawi, Kota Kinabalu, and several secondary Malaysian cities from Singapore. Unlike most budget airlines on this list, its base fare includes checked baggage of up to 30kg and a complimentary in-flight meal, positioning it closer to a hybrid carrier than a pure no-frills operation. Its Airbus A320 and Boeing 737 fleet keeps the route network flexible across both short hops and slightly longer regional flights.

India's largest airline by market share operates budget routes from Singapore to Chennai, Kolkata, Mumbai, and Hyderabad out of Terminal 1. The base fare covers a 7kg cabin bag, with a 15kg checked allowance available as a paid extra. IndiGo's on-time performance consistently ranks among the strongest of any carrier serving this route, a detail worth weighing for travellers with tight onward connections.

VietJet links Singapore with Ho Chi Minh City, Hanoi, Da Nang, and Nha Trang, and its fares occasionally dip below SGD 30 during promotional periods, among the lowest on this list. The base fare excludes checked baggage entirely, so travellers packing more than a cabin bag should budget for that add-on separately. Its SkyBoss and SkyBoss Business tiers offer upgraded seating and baggage allowances for travellers wanting more than the bare-bones fare.

This carrier flies Singapore to Bangkok's Don Mueang Airport, a useful alternative for travellers who'd rather avoid the more congested Suvarnabhumi. Fares run noticeably lower during off-peak periods, and the airline's Airbus A330 aircraft handle the route on select high-demand days. Like most budget carriers on this list, checked baggage comes as a separate paid add-on beyond the included 7kg cabin allowance.

Regional budget fares tend to bottom out roughly two to three months before departure, well before last-minute pricing kicks in.

Tuesday and Wednesday departures consistently price lower than weekend flights across nearly every carrier on this list, a pattern that holds across most Southeast Asian budget routes.

Adding baggage, seat selection, or a meal during initial booking almost always costs less than paying for the same add-ons at the airport later.

A Singapore River cruise, bookable through Traveloka's activities listings, fills a layover afternoon nicely if your connecting flight leaves you a few spare hours in the city.

Cross-checking a route across two or three of these carriers before committing often turns up a meaningfully cheaper fare, since promotional pricing rarely aligns across airlines at the same time. Flexible date searches widen the gap further, occasionally shifting a fare by a full price bracket just by moving a departure a day or two either direction.

A car rental at your destination rounds out a budget trip nicely once the flight is booked, and an airport transfer from Changi gets you to check-in without cutting it close on an early departure.

Eight airlines means eight different fare calendars to track, which gets considerably simpler with everything compared in one place.
