Which Day of the Week Is Cheapest to Fly from Singapore in 2026?

Monday is most often the cheapest day of the week to fly from Singapore in 2026. On KAYAK's 12-month data for nine popular routes, checked in October 2026, Monday was cheapest on five routes (Bangkok, Tokyo, Hong Kong, Seoul and London), Tuesday on two (Kuala Lumpur and Taipei) and Sunday on two (Bali and Sydney). Fly early in the week where you can, check your own route's fare calendar, then go through ShopBack Singapore before you book.

New to ShopBack? ShopBack Singapore is a free website and app that returns cash on eligible online bookings and orders at sites including Trip.com and Skyscanner. You start from ShopBack, book on the site as usual, and the cash lands in your ShopBack account once the booking is confirmed. Create a free ShopBack account before your next flight search.

Which day of the week is cheapest to fly from Singapore?

Monday is the cheapest day to fly on more popular routes from Singapore than any other day, with Tuesday and Sunday next. KAYAK publishes a cheapest day of the week for each route, based on deals its users found over the previous 12 months. Here is what its Singapore route pages showed when we checked in October 2026:

Route from Singapore (SIN)	Cheapest day to fly	Cheapest month	Book ahead to save
Bangkok (BKK)	Monday	January	At least 26 weeks: around 38%
Kuala Lumpur (KUL)	Tuesday	January	At least 4 weeks: around 16%
Tokyo (TYO)	Monday	January	At least 17 weeks: around 15%
Bali, Denpasar (DPS)	Sunday	January	At least 25 weeks: around 35%
Hong Kong (HKG)	Monday	January	At least 13 weeks: around 29%
Taipei (TPE)	Tuesday	January	At least 5 weeks: around 9%
Seoul (SEL)	Monday	August	At least 5 weeks: around 15%
Sydney (SYD)	Sunday	March	At least 26 weeks: around 30%
London (LON)	Monday	January	At least 18 weeks: around 17%

Source: KAYAK Singapore route pages, at the time of writing. The "book ahead" column is KAYAK's figure for the saving compared with booking last minute.

The gap can be real money. On the Singapore to Bangkok route, KAYAK's page said Monday was about 13% cheaper than the average day, while Friday was the most expensive day at about 10% above average.

So the honest answer is: start with Monday or Tuesday, but check the route. Seven of the nine routes favoured an early-week departure. Bali and Sydney, two of the most popular leisure trips from Singapore, were cheapest on a Sunday. If you are flexible, a fare calendar for your exact route will tell you more than any general rule.

Why early-week flights from Singapore are often cheaper

Fares usually follow demand, and demand from Singapore usually peaks around the weekend. Many leisure travellers leave on a Thursday or Friday and come back on a Sunday or Monday, and business travel adds its own peaks. Seats on quieter days are more likely to be priced lower to fill the plane.

That is a pattern, not a law. A route with a lot of weekend flights or a big holiday crowd at the other end can flip it, which is likely why Bali and Sydney showed Sunday as the cheapest day. Use the day of the week as one lever, next to the month and how early you book.

Flight ticket prices from Singapore in 2026: what moves them

Three things usually move a flight ticket price from Singapore more than the day of the week: the month, how early you book, and whether you travel in a holiday period. Here is what the data says for each.

How early you book. On KAYAK's route pages, the saving from booking ahead ranged from around 9% (at least 5 weeks ahead to Taipei) to around 38% (at least 26 weeks ahead to Bangkok), compared with booking last minute. Short hops like Kuala Lumpur needed only about 4 weeks to see a saving of around 16%. Longer or busier leisure routes, such as Bali (around 35% at 25 weeks) and Sydney (around 30% at 26 weeks), rewarded planning months ahead.

School holidays. MOE's 2026 school calendar sets the June holidays from 30 May to 28 June and the year-end holidays from 21 November to 31 December, with one-week breaks from 14 to 22 March and 5 to 13 September. These are the weeks many Singapore families travel, so fares on popular routes are usually higher.

Festive periods and long weekends. Chinese New Year, Hari Raya, Deepavali and the Christmas season usually push up demand, and public holidays next to a weekend tend to fill flights quickly.

What you add at checkout. A cheap base fare can end up costing more once checked baggage, seat selection and meals are added, especially on low-cost airlines. Compare the total for the ticket you actually need.

Flight ticket best deals in Singapore in 2026: how to find them

The best flight ticket deals from Singapore in 2026 usually come from combining a cheap day, a cheap month and an early booking, then lowering the final price at checkout. This guide does not list live fares, because they change by the hour. Use this routine instead:

1. Pick the cheapest day. Start with Monday or Tuesday, then check your route's own data.
2. Look at the whole month. Use a whole-month or calendar view on a flight search site to see which dates are lowest.
3. Book early for long or holiday routes. Months ahead for places like Bali, Bangkok and Sydney; a few weeks for short hops like Kuala Lumpur.
4. Set a price alert if your trip is far off, so you hear when the fare drops.
5. Compare the total, with baggage, on the site where you would pay.
6. Go through ShopBack before you book. Booking through ShopBack lowers the cost of the trip, and you still book on the site you chose.

Cheapest month to fly from Singapore in 2026: price data

January was the cheapest month to fly on seven of the nine routes we checked on KAYAK, with Seoul cheapest in August and Sydney in March. KAYAK works out its cheapest month by taking all return prices for each month over the past 12 months, removing extreme outliers and averaging the rest. The cheapest-month return averages its pages showed in October 2026 were:

• Kuala Lumpur: January, at S$118 return
• Bali (Denpasar): January, at S$178 return
• Bangkok: January, at S$219 return
• Taipei: January, at S$286 return
• Hong Kong: January, at S$350 return
• Seoul: August, at S$456 return
• Tokyo: January, at S$483 return
• Sydney: March, at S$625 return
• London: January, at S$970 return

These are past averages from KAYAK's data at the time of writing, not live fares or a promise of future prices. Note that January sits just after the year-end school holidays end on 31 December, which fits the pattern of fares easing once the holiday crowd is home.

Trip.com vs Skyscanner flight ticket price comparison in 2026

Trip.com and Skyscanner are not the same kind of site, so the fair comparison is the final price you pay, not the first number you see. Trip.com is a booking site: you choose the flight and pay Trip.com for the ticket. Skyscanner is a search site that compares fares across airlines and booking sites, then sends you to one of them to pay. According to its Wikipedia entry, Skyscanner is owned by Trip.com Group, does not sell tickets or process payments itself, and works with around 1,200 partners.

A simple way to compare:

• Search widely first. Skyscanner and KAYAK are useful for spotting the cheapest day or month on a route. Skyscanner's "Everywhere" search shows the cheapest destinations from a given city.
• Check the same flight on the booking site. Look up the exact flight, date and fare type on Trip.com, and on the airline's own site if you like.
• Compare like for like. Same baggage allowance, same change and refund rules, same total.
• Read the booking site's own guarantees. According to Trip.com's Service Guarantee page at the time of writing, its Flight Price Guarantee means the price of your flight will not change after payment is confirmed, and if a ticket is not issued after successful payment because of Trip.com's fault and the price rises, Trip.com covers the difference. Trip.com also lists 24/7 customer support by phone, email and online chat. Exclusions apply, for example flights departing within 2 hours of booking.

Trip.com, Skyscanner and KAYAK: a simple workflow for flight tickets from Singapore

Use KAYAK or Skyscanner to find the cheapest day and month, then book on the site you choose after going through ShopBack. In practice:

1. Find the cheap dates. Check KAYAK's route data for your destination, or Skyscanner's month view.
2. Shortlist two or three flights on your cheapest dates.
3. Price the exact flight on Trip.com and compare the total with baggage.
4. Go through ShopBack. Open the Trip.com page or the Skyscanner page on ShopBack Singapore, tap through and book in one session.

Other travel sites in the same category on ShopBack Singapore include Expedia, Agoda, Booking.com, Traveloka and Klook, so it is worth checking one of them for hotels and activities on the same trip.

Why ShopBack is a step before you book

Booking through ShopBack lowers the cost of the trip, and you still book on the site you chose. Before you check out, go through ShopBack to get a post-purchase discount on the order. The step takes a few seconds:

1. Open the ShopBack Singapore app or website.
2. Search for Trip.com or Skyscanner.
3. Tap through from the ShopBack page and complete your booking as normal.
4. Once the booking is confirmed, the cash is added to your ShopBack account.

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.

Your effective price is what you pay at checkout minus the cash ShopBack returns. Here is an illustrative example: on a S$400 return flight to Tokyo booked at an illustrative 5% rate, S$20 comes back, so the effective price is S$380. The real rate is shown on the Trip.com page on ShopBack Singapore and can differ by booking type and change during campaigns, so check it on the day you book. What is eligible also differs by site, so check the store page before you tap through.

Do promo codes and ShopBack work on the same booking?

Usually, yes, but not always. A booking site promo code lowers the price you pay, and going through ShopBack applies to that amount. Some codes, payment methods or booking types can be excluded, so check the merchant's terms on the ShopBack store page before you pay.

Step by step: the cheapest way to fly from Singapore

1. Choose your day. Start with Monday or Tuesday; check whether your route is a Sunday exception like Bali or Sydney.
2. Choose your month. January was cheapest on most routes we checked; avoid school holidays if you can.
3. Book ahead. Weeks ahead for short hops, months ahead for long or holiday routes.
4. Compare the total with baggage on the site where you would pay.
5. Go through ShopBack Singapore and book in the same session.

Weekdays are usually cheaper. Seven of the nine routes we checked on KAYAK had a Monday or Tuesday as the cheapest day to fly. The two exceptions, Bali and Sydney, were cheapest on a Sunday, so the rule is a starting point, not a guarantee.

January was the cheapest month on seven of the nine routes we checked on KAYAK in October 2026, including Bangkok, Kuala Lumpur, Tokyo, Bali, Hong Kong, Taipei and London. Seoul was cheapest in August and Sydney in March. The cheapest month for your trip depends on the route, so look at a whole-month fare view before you pick dates.

Longer and holiday routes usually reward booking earlier.

Is Trip.com or Skyscanner cheaper for flight tickets?

Neither is cheaper every time, because they do different jobs. Trip.com is a booking site where you pay for the ticket. Skyscanner is a search site that compares fares and sends you to an airline or booking site to pay. Use Skyscanner or KAYAK to find the cheapest date, then compare the final price, with baggage, on the site where you would pay.

Does Skyscanner sell flight tickets?

No. Skyscanner is a travel search site owned by Trip.com Group. It does not sell tickets or take payment itself; bookings are completed with one of its airline or booking site partners, so the partner's terms apply to your ticket.

What is Trip.com's Flight Price Guarantee?

According to Trip.com's Service Guarantee page at the time of writing, Trip.com guarantees that the price of your flight will not change after payment is confirmed, and if a ticket is not issued after successful payment because of Trip.com's fault and the price rises, Trip.com covers the difference. Exclusions apply, such as flights departing within 2 hours of booking.

When are flight tickets from Singapore usually more expensive?

How does ShopBack lower the cost of a flight ticket?

Before you check out, go through ShopBack to get a post-purchase discount on the order. You tap through from the ShopBack Singapore page for Trip.com or Skyscanner, book as usual on that site, and cash comes back to your ShopBack account once the booking is confirmed. Your effective price is what you paid minus that cash.

Can I use a promo code and still go through ShopBack?

Usually, yes. A booking site promo code lowers the price you pay, and going through ShopBack applies to that amount. Some codes, payment methods or booking types can be excluded, so check the merchant's terms on the ShopBack store page before you pay.

Is cashback the same as airline miles?

No. Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles that you can only spend with one airline or app.
