London from $400–$800 (on Singapore Airlines or with Gulf carrier stopovers). Melbourne/Sydney from $300–$600 on Scoot or Jetstar. Long-haul fares fluctuate significantly — set up fare alerts and wait for sales. Singapore Airlines typically runs 2–3 major fare sales per year with long-haul deals.

Budget Airlines Comparison

Singapore is served by more budget airlines than almost any other city. Here is what each one does best.

MOST DESTINATIONS

Scoot

Singapore Airlines' budget arm with the widest network from Changi. Direct flights to Japan, Korea, Australia, India, and across Southeast Asia. Runs “Take Off Tuesday” sales weekly. The best budget carrier for long-haul from Singapore. Operates from Terminal 1.

AirAsia

The largest budget airline in Southeast Asia. Strongest coverage for Malaysia, Thailand, Indonesia, Vietnam, and the Philippines. Runs frequent “BIG Sale” promotions with fares from $0 (plus taxes). Operates from Terminal 4.

Jetstar Asia

Good for Australia routes and select Asian destinations. “Friday Fare Frenzy” sales every week. Solid option for Bangkok, Bali, and Australian cities. Operates from Terminal 1. Often competitive with Scoot on overlapping routes.

VietJet & Cebu Pacific

Specialists for Vietnam and the Philippines respectively. VietJet often has the cheapest fares to Ho Chi Minh City and Hanoi. Cebu Pacific runs frequent promo fares to Manila and Cebu. Worth checking when these specific destinations are your target.

When to Book for the Cheapest Fares

The Timing Sweet Spot

For most Southeast Asia routes, book 6–8 weeks before departure. For Japan/Korea, book 2–3 months ahead. For Europe and long-haul, book 3–4 months ahead. These windows balance airline inventory management (prices rise as seats fill) with promotional pricing (too far ahead and fares are at baseline).

Best Days to Book & Fly

Booking day does not matter as much as myths suggest, but flying midweek (Tuesday, Wednesday, Thursday) is consistently 15–30% cheaper than Friday–Sunday departures. Red-eye flights (departing after 10 PM) are often the cheapest time slot. Early morning flights (before 7 AM) are the second-cheapest.

Peak vs Off-Peak Months

Cheapest: January (post-NYE), March, May, September–November. Most expensive: June (school holidays), December (year-end), Chinese New Year week, and any public holiday long weekend. For the absolute lowest fares, book off-peak travel on midweek flights. Price difference can be 50–100%.

Best Flight Comparison Tools

BEST OVERALL

Google Flights

The most reliable flight comparison tool for Singapore. Features: flexible date calendar (see cheapest fares across a month), Explore map (find cheapest destinations), price tracking with alerts, and accurate real-time pricing. Start here for every search.

Skyscanner

Best for the “Everywhere” search — search Singapore to Everywhere to find the cheapest destination for your dates. Also has a strong “Whole Month” view for flexible travellers. Good at finding budget airline fares that Google Flights sometimes misses.

Airline Websites (Direct)

During sales, always check the airline's own website. Scoot's “Take Off Tuesday” and AirAsia's “BIG Sale” fares often appear on their websites before aggregators pick them up. Booking direct also gives you better customer service and easier changes.

Flight Booking Hacks

Set Up Price Alerts

Use Google Flights to track prices for your desired route and dates. You will receive email notifications when the price drops. This passive approach catches sales and price dips without you constantly checking.

Skip Checked Baggage

On budget airlines, checked baggage adds $20–$60 per flight. For short trips (3–5 days), pack in a 7kg cabin bag and save. This is the single easiest way to keep budget airline fares truly budget.

Use Incognito/Private Browsing

While the impact of browser cookies on flight pricing is debated, using incognito mode ensures you see baseline prices without any personalisation. It takes 2 seconds and costs nothing.

Consider Nearby Airports

For Japan, flying into a secondary airport (Osaka instead of Tokyo, or Fukuoka) can save $50–$100. For Thailand, flying into Don Mueang (DMK) instead of Suvarnabhumi (BKK) often gives cheaper fares on budget carriers.

Book Through ShopBack

ShopBack offers 0.5–3% cashback on airline bookings when you click through their platform. On a $500 flight, that is $2.50–$15 back. Small but free money.

Credit Card Flight Deals

Several Singapore credit cards offer perks that reduce the effective cost of flying. See our cashback credit cards guide for a full comparison.

Miles Cards

For frequent travellers, miles credit cards (Citi PremierMiles, UOB PRVI Miles, DBS Altitude) earn 1.2–4 miles per dollar spent. Accumulated miles can be redeemed for free flights on SIA, Star Alliance, and other partners. A domestic SIA flight to KL costs just 7,500 KrisFlyer miles one-way. You can compare the best miles credit cards on SingSaver to find the right card for your travel style.

Complimentary Travel Insurance

Several premium cards include free travel insurance when you book flights with the card. This saves $30–$80 per trip on travel insurance. Check your card's benefits before buying a separate policy.

Airport Lounge Access

Cards with Priority Pass or Plaza Premium access give you free airport lounge entry (normally $40–$60 per visit). Useful for early morning flights and long layovers. DBS Insignia, Citi Prestige, and UOB PRVI Miles offer lounge access at various tiers.

Error Fares & Flash Sales

Error fares happen when airlines accidentally publish fares at the wrong price — sometimes $200 for business class or $50 for a long-haul flight. Flash sales are intentional but time-limited deep discounts.

How to Catch Error Fares

Follow WhyNotDeals and flight deal communities. Error fares are posted within minutes of discovery and typically get corrected within hours. When you spot one: book immediately, ask questions later. Most airlines honour error fares if the ticket is issued. Check our deals page for the latest flight deals.

Regular Flash Sales

Scoot: “Take Off Tuesday” every week. AirAsia: “BIG Sale” 4–5 times per year. Jetstar: “Friday Fare Frenzy” weekly. SIA: Major sale 2–3 times per year (usually March and November). Set reminders for these recurring sales.
