Firefly Extends Singapore-Kuala Lumpur Flight Halt as Haze Worsens
Firefly has extended its suspension of flights between Kuala Lumpur and Singapore through Wednesday because of smoke from fires in Indonesia. Al Jazeera Poor visibility has made the short hop unsafe to operate.
The cancellations cover services between Sultan Abdul Aziz Shah Airport (SZB) near Kuala Lumpur and Seletar Airport (XSP) in Singapore, which the airline attributed to "weather and haze conditions". Firefly, a subsidiary of Malaysia Aviation Group which also includes Malaysia Airlines, said affected passengers were being rebooked on Malaysia Airlines flights between Kuala Lumpur International Airport and Singapore's Changi Airport, subject to seat availability.
The disruption built in stages. Firefly first announced cancellations on October 10, citing low visibility from haze. Its initial notice on October 9 covered flights to and from Seletar from October 10 to 12 as a precautionary safety measure. Firefly The airline then extended the halt to October 13, pointing to haze and poor weather at Seletar, The Straits Times before the latest extension through Wednesday reported on October 13.
Air quality readings explain the limits. The Air Quality Index, or AQI, is a scale where higher numbers mean dirtier and less healthy air. On October 13, IQAir ranked Singapore and Kuala Lumpur as the world's two most polluted cities, with an index of 199 in Singapore and 183 in Kuala Lumpur. The decline was rapid. On October 8, Kuala Lumpur was among the top 10 most polluted cities globally, with smoke from fires in Sumatra and Kalimantan cited for the decline. IQAir By October 9, Kuala Lumpur was ranked the most polluted major city.
The source is wildfires in parts of Indonesia. They had been burning for weeks as of mid-October, sending smoke into Malaysia and Singapore. The fires, concentrated mostly on Sumatra and Borneo, are Indonesia's most intense in 11 years. Jakarta has deployed about 60,000 personnel to fight them. Thick smoke grounded 34 aircraft, including planes and helicopters, limiting aerial firefighting.
The effects reach beyond aviation. Schools in Malaysia were shut in early October due to toxic smog from the Indonesian fires. Singapore reintroduced subsidised care for haze-related illnesses, a step it last took in 2015.
The broader context here will be familiar to officials who manage haze that drifts across borders. Flight decisions, health subsidies and school closures tend to move together when smoke persists, spreading costs across operators, clinics and households. In my view, the sequence to watch is whether the suspension holds past Wednesday, whether the AQI gap between Singapore and Kuala Lumpur narrows or widens, and whether Indonesia's large ground deployment can operate effectively while its aircraft remain grounded. Each will indicate whether the disruption eases quickly or extends.
