MYAirline (MYM, Kuala Lumpur Subang) will begin international operations on June 28, 2023, with daily roundtrips between Kuala Lumpur International and Bangkok Suvarnabhumi, and Kuala Lumpur - Bangkok Don Mueang using A320-200 equipment. The launch of international services follows the carrier starting domestic flights in early December 2022.

By mid-August, MYAirline plans to operate twice daily roundtrips on both routes into Bangkok. The carrier will take on AirAsia, Batik Air Malaysia, and Thai AirAsia on the Kuala Lumpur - Bangkok Don Mueang route, where AirAsia offers a commanding 65.65% of all seats available on the sector. On the Kuala Lumpur - Bangkok Suvarnabhumi route, MYAirline will compete with Thai AirAsia, Thai Airways International, AirAsia X, and Malaysia Airlines. While more airlines fly on the sector into Bangkok Suvarnabhumi, there are approximately 50% less seats available on a weekly basis compared to the Kuala Lumpur - Bangkok Don Mueang route.

MYAirline recently secured approval from the Malaysian Aviation Commission (MAVCOM) to operate seven roundtrips a week between Kuala Lumpur and Phuket which comes into effect immediately. In March, the carrier was also granted approval to fly 14 roundtrips a week between Kuala Lumpur and Singapore Changi. MYAirline has MAVCOM approval to operate across 24 domestic routes. Ahead of its international launch, the airline is flying on nine of those routes.
