Senai International Airport (IATA: JHB, ICAO: WMKJ), officially known as Sultan Ismail International Airport (Malay: Lapangan Terbang Antarabangsa Sultan Ismail), is an airport located in the town of Senai, near Johor Bahru, Malaysia. The airport is the secondary hub for Firefly.
Opened in 1974, it serves the state of Johor as well as people from the southern states of Peninsular Malaysia. Senai International Airport used to be hubs of AirAsia and used to serve as a domestic hub of Malaysia Airlines until the rationalisation of its domestic routes to cut the company's losses. As a result, Malaysia Airlines only served two destinations from Senai after the rationalisation.
