Monspace Sky Airlines (Kuala Lumpur Subang) and Suasa Airlines (Kuala Lumpur Subang) have landed themselves in hot water with the Malaysian Aviation Commission (MAVCOM) after local media reports showed the two had collaborated in holding a launch flight this weekend despite neither being certified to do so.

MAVCOM said in a statement that it has now launched formal investigation into Suasa Airlines given that it does not possess either an Air Services Permit (ASP) let alone an Air Operators Certificate (AOC) both of which are required before any form of passenger service can be carried out.

"Suasa Airlines filed an application with MAVCOM to operate a commercial flight from Kuala Lumpur International to Langkawi on July 22, 2016, which MAVCOM rejected. However, on the same day, Suasa Airlines continued to operate this flight as a 'demonstration flight' which is now being investigated by MAVCOM," it said.

Pictures circulating on social media show Suasa Air's B737-400 - 9M-SUA (msn 27097) - sporting the titles of Monspace Sky Airlines, a self-styled virtual carrier. MAVCOM says that since Monspace lacks any official documentation and has been marketing itself as an airline in contravention of local laws, it has now called for a police investigation.

"MAVCOM would also like to advise consumers to refrain from making any flight arrangements with Suasa Airlines and Monspace Sky Airlines to ensure that they do not face any inconvenience in their travels," it ended.
