Firefly has cancelled all scheduled Subang–Singapore flights from 10 to 12 October 2026 as haze and poor visibility affect operations at Singapore’s Seletar Airport. Passengers booked on the route are being offered available Malaysia Airlines seats through different airports or a full refund if they decline the alternative.
The cancellation covers both directions between Sultan Abdul Aziz Shah Airport in Subang (SZB) and Seletar (XSP), including Monday, 12 October. Firefly describes the move as a safety precaution and says it will contact affected customers as conditions change, according to its travel advisory and a statement reported by CNA.
Which Firefly Subang–Singapore Flights Are Cancelled?
The affected daily services are FY3122, FY3124, FY3126, FY3128, FY3130 and FY3132 from Subang to Seletar, with FY3123, FY3125, FY3127, FY3129, FY3131 and FY3133 in the reverse direction. Firefly has cancelled the scheduled services on this route for the three-day period, according to The Straits Times, which obtained the airline’s response.
This notice concerns the Subang–Seletar route. It does not say that every Firefly flight, every Malaysia–Singapore flight or either airport has shut down. Travellers with other itineraries should check their own booking status with the operating airline before making new plans.
What Can Affected Passengers Do?
Firefly says it is contacting passengers and reallocating them to Malaysia Airlines services between Kuala Lumpur International Airport (KUL) and Singapore Changi Airport (SIN), subject to available seats. That replacement journey starts and ends at different airports from the original Firefly ticket. Passengers should check the revised departure time, airport and transport arrangements before accepting it.
- Check the booking: Look for a direct message from Firefly and verify the current flight status through the airline’s official channels. Keep the booking reference close to hand.
- Review the alternative: A Malaysia Airlines seat is subject to availability. Confirm both the KUL departure and SIN arrival details before arranging travel to the airports.
- Choose a refund if the alternative does not work: Firefly says passengers who do not proceed with the reallocated flight are eligible for a full refund to the original payment method within 30 working days.
- Get help directly: Firefly’s AskFY support page links to its flight disruption assistance and refund channels. Keep any cancellation notice and booking correspondence.
The airline has not announced a cash payment for ground transport between Subang and KLIA or between Seletar and Changi. Travellers should confirm any additional costs and onward connections with Firefly before committing to a replacement trip.
Why Is Haze Affecting Seletar?
Firefly cited weather and haze conditions affecting Seletar Airport. Singapore’s National Environment Agency said on 9 October that more hotspots in southern and central Sumatra, combined with unfavourable winds, had worsened haze across the region. The agency warned that winds could continue carrying smoke towards Singapore over the weekend.
Conditions can differ sharply by location and hour. CNA reported that 14 Malaysian areas had air quality in the unhealthy range at 1 pm on Sunday, 11 October, while Singapore’s 24-hour air quality index remained unhealthy across its five regions. Readers can check Malaysia’s official Air Pollutant Index portal for newer local readings; those readings do not themselves establish whether a particular flight can operate.
What Happens After Monday?
Firefly says it is monitoring the weather and will communicate schedule updates directly to affected customers. No broader suspension beyond 12 October was announced in the airline’s advisory reviewed for this report. Passengers due to travel later in the week should check their booking rather than assume their flight has been cancelled or restored.
The disruption matters for travellers who chose the smaller Subang and Seletar airports for a short cross-border trip: the offered replacement uses KLIA and Changi, so the ground journey may change at both ends.
