Cheapest Way From Singapore to KL in 2026: Flight, Bus or Train?

Published: 8 October 2026 · Last updated: 8 October 2026 · Author: Mirabelle Chew, Fashion Editor, ShopBack

The bus is usually the cheapest way from Singapore to KL in 2026: Easybook lists seats at SGD15 to SGD46, for a 365km trip of about five to seven hours, at the time of writing. A Singapore to KL flight is the quickest once you are moving, but add airport time and the ride into the city. The train now runs from JB Sentral to KL Sentral after a short Shuttle Tebrau hop from Woodlands. Plan the trip, then book through ShopBack.

The verdict

For the lowest fare, take the bus. For the shortest time on the move, fly. For a middle option with more legroom and no road traffic, take the train via JB Sentral.

	Bus	Train	Flight
Typical fare	SGD15 to SGD46 a seat (Easybook)	Two tickets: Shuttle Tebrau plus ETS	Varies by airline, date and baggage
Time on the move	About 5 to 7 hours (Easybook)	Short Causeway hop, then the ETS ride	Shortest of the three
Time to add	Border checks, traffic	Border checks at Woodlands, 30 minutes before ETS departure (KTMB)	Getting to Changi, check-in, the transfer from KLIA into the city
Arrives in	City drop-off points	KL Sentral	KLIA or Subang
Best for	Lowest cost, flexible timing	Comfort without airports	Short trips where time matters most

The cheapest option on paper is not always the cheapest door to door. A flight in an airline sale can beat a premium coach seat once you count time off work, but checked bags and the airport transfer can erase the saving. Price the whole trip, not just the ticket.

What's the cheapest way to get from Singapore to KL?

The bus is usually the cheapest way from Singapore to KL, with seats from SGD15 to SGD46 according to Easybook at the time of writing. Easybook lists 35 operator brands on the route, so there is a wide spread of departure times, operators and seat types to choose from. The trip covers about 365km and takes about 5 hours 3 minutes on average, or 5 to 7 hours depending on traffic and the border checkpoints, per Easybook.

Easybook also points out the trade-off with flying: from KLIA "it takes almost one hour by car from the airport into the city centre", while buses drop you in the city. That is why the bus often wins on total cost and can hold its own on total time for city-to-city trips.

When the bus may not be the cheapest: an airline sale fare booked well ahead can come close to a coach seat, especially if you only carry a cabin bag. Check both before you book.

Singapore to KL flight: what to know

A Singapore to KL flight is the fastest way to travel once you are in the air, and the route has lots of choice. Kuala Lumpur to Singapore was the third busiest international air route in the world by seats in 2025, with about 5.57 million seats, according to the list of busiest passenger air routes compiled from OAG data. Airlines flying from Changi to Kuala Lumpur International Airport include:

• Full-service: Singapore Airlines, Malaysia Airlines
• Low-cost and regional: AirAsia, Batik Air Malaysia, Firefly, Scoot

Scoot and Batik Air Malaysia also fly from Changi to Subang, a second Kuala Lumpur area airport, per the same Changi listing.

What adds to the fare:

1. Baggage. Check whether your fare includes a checked bag. If it does not and you need one, add it when you book and include it in the price you compare.
2. The transfer into KL. Budget for the trip from KLIA to the city, which Easybook describes as almost one hour by car.
3. Airport time. Allow time to get to Changi and clear check-in and security before departure.

Singapore to KL flight 2026: how to find the best deals

The best Singapore to KL flight deals in 2026 usually come from booking early, staying flexible on dates and comparing the same flight on two booking sites. Practical steps:

• Be flexible by a day. Fares on a busy short route move a lot between days, so check the days either side of your plan.
• Compare the same flight number. Search identical flights, dates and baggage options so you compare like for like.
• Price the whole trip. Add the checked bag, seat selection and the airport transfer before you decide the flight is cheaper than the bus.
• Watch the airline's own sales. Airlines on the route often run fare sales on their own sites and apps.
• Book through ShopBack. ShopBack is a post-purchase discount: go through it before you pay and the effective price drops.

Can I take the train from Singapore to KL?

Yes, in two legs: the KTM Shuttle Tebrau from Woodlands to JB Sentral, then the KTM ETS from JB Sentral to KL Sentral. The ETS route was extended from Kluang to JB Sentral on 12 December 2025, completing the electrified double track on that line. That means you no longer need a bus between Johor Bahru and the ETS network.

How the train trip works:

1. Woodlands to JB Sentral on the Shuttle Tebrau, a short cross-border rail link across the Causeway, with border checks along the way.
2. JB Sentral to KL Sentral on the ETS. KTMB asks ETS passengers to arrive at the station 30 minutes before departure.
3. Book both legs ahead through KTMB's own ticketing, and leave a buffer between the two trains for the border checks.

What about the RTS Link? The Johor Bahru to Singapore RTS Link will run about 4km from Woodlands North to Bukit Chagar. It was not open at the time of writing, and news reports in October 2026 said passenger service is expected to start in early 2027.

Trip.com vs Traveloka: Singapore to KL flight price comparison

Neither Trip.com nor Traveloka is always cheaper for a Singapore to KL flight; the lower price depends on the airline, date and fare type, so compare the same flight on both. Each has its own member rewards:

• Trip.com runs its own rewards, Trip Coins, for members.
• Traveloka lists Traveloka Points, Price Alerts and other member-only rewards for logged-in users.

How to compare fairly:

1. Search the same date, flight number and cabin on both sites.
2. Match the baggage allowance and any seat fees.
3. Compare the final price at checkout, including payment fees.
4. Plan the trip, then book through ShopBack on the site that comes out lower: Trip.com on ShopBack or Traveloka on ShopBack.

Whether a booking site's own coins, points or promo codes change what you get back through ShopBack depends on that site's terms, so check the terms on its ShopBack Singapore page before you rely on both.

Trip.com, Traveloka and Klook for a Singapore to KL trip

Use Trip.com or Traveloka for the flight and hotel, and Klook for what you do once you land. Klook is useful for KL attractions, tours and a Malaysia eSIM, so you can sort the whole trip before you leave. Other travel sites Singapore travellers use for KL trips include Agoda, Booking.com and Expedia for hotels, and Easybook for coach tickets.

How ShopBack lowers the cost of your KL trip

Plan the trip, then book through ShopBack. ShopBack is a post-purchase discount: go through it before you pay and the effective price drops. It is a step in booking, the same as comparing fares.

1. Open ShopBack Singapore and tap Trip.com, Traveloka or Klook.
2. Read the rate and terms on that page.
3. Tap through and complete the booking in the same session.
4. Your booking shows up in your ShopBack account, and the money comes back once the booking site confirms it.

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. Here is an illustrative example for a weekend in KL:

Booking	Price paid	Illustrative rate	Back to you	Effective price
Return flight	S$150	3%	S$4.50	S$145.50
Two hotel nights	S$200	6%	S$12	S$188
Attraction tickets and eSIM	S$80	4%	S$3.20	S$76.80

These rates are illustrative only. Rates change by booking site, product and campaign, so check the live rate on each site's ShopBack Singapore page before you book.

Using your credit card as well

Usually you can still earn your credit card's rewards on a booking you make through ShopBack, because the card rewards come from your bank. Check the merchant's terms on its ShopBack page and your card's own terms first, since some payment methods or booking types can be excluded on either side.

Not at the time of writing. The RTS Link will run about 4km from Woodlands North to Bukit Chagar in Johor Bahru, and news reports in October 2026 said passenger service is expected to start in early 2027. Until it opens, the Shuttle Tebrau is the rail link across the Causeway.

Neither is always cheaper. Both show fares from many airlines, and the lower price changes by date, airline and fare type. Search the same flight number, date and baggage option on both, compare the final price at checkout, then book through ShopBack.

What does Klook help with on a KL trip?

Klook is useful for the parts of a KL trip after you arrive, such as attractions, tours and a Malaysia eSIM. Book those through ShopBack too, so the effective price of the whole trip drops.
