Malaysia Airlines (MAB) and Singapore Airlines (SIA) have launched their strategic joint business partnership, formalised in January 2026 following the regulatory approvals, with the introduction of joint fare products for travel between Singapore and Kuala Lumpur.
The new joint fare offerings build on the airlines’ existing codeshare partnership, enabling MAB and SIA to provide customers with a greater variety of fare options between the two capital cities, as well as enhanced connectivity across the combined network of both carriers.
The Kuala Lumpur-Singapore route is consistently one of the absolute busiest international air routes in the world. According to a recent global airline capacity assessment, it ranks as the third busiest international route in the world, just behind Hong Kong–Taipei and Cairo–Jeddah. It has previously held the number one spot in recent years.
MAB and SIA are also working towards the progressive introduction of additional customer benefits, including reciprocal lounge access, coordinated flight schedules, and joint corporate travel arrangements. These initiatives reflect the airlines’ deepening commercial collaboration and shared commitment to improving connectivity between Malaysia, Singapore, and the wider region.
Bryan Foong, Chief Executive Officer of Airline Business, Malaysia Aviation Group, said: “This joint business partnership with Singapore Airlines marks a significant milestone in the expansion of our commercial collaboration. By introducing joint fare products, we are giving our customers greater choice, improved flexibility, and a more seamless travel experience. This collaboration also lays the foundation for deeper integration across our networks, ultimately benefiting both leisure and business travellers.”
Lee Lik Hsin, Chief Commercial Officer, Singapore Airlines, said: “The introduction of joint fare products with Malaysia Airlines expands the range of fare options available to customers travelling between Singapore and Kuala Lumpur, offering more flexibility and convenience when planning their journeys. As we deepen our collaboration, we will continue to combine our strengths to enhance both airlines’ offerings and deliver greater value to customers, while strengthening the long-standing people-to-people connections and trade links between Singapore and Malaysia.”
Since signing their commercial cooperation framework agreement in October 2019, MAB and SIA have progressively expanded their collaboration, offering customers greater connectivity and more travel options.
The airlines currently codeshare on services across Malaysia, Singapore, Europe, and South Africa. In addition, both carriers introduced reciprocal accrual and redemption between the Enrich and KrisFlyer frequent flyer programmes in February 2024, allowing members to earn and redeem miles or points on selected flights operated by both carriers.
