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.
