Firefly has extended the cancellation of all flights between Subang and Singapore through October 14. Thick haze across the cross-border corridor cut visibility.
The suspension affects six daily return services between Sultan Abdul Aziz Shah Airport and Singapore’s Seletar Airport. The airline initially halted the route from October 10 to October 12. It then pushed the restart date back.
Disrupted Schedules Across the Causeway
Grounded flights cover services FY3122 and FY3123, FY3124 and FY3125, FY3126 and FY3127, FY3128 and FY3129, FY3130 and FY3131, and FY3132 and FY3133. Together, the pairings make up the carrier’s daily shuttle between the two secondary hubs.
Firefly is rebooking affected passengers onto parent company Malaysia Airlines flights out of Kuala Lumpur International Airport, subject to seat availability. Travelers who decline the alternate itineraries can claim a full refund to their original payment channel within 30 working days.
Air Quality Readings in Singapore
Pollution levels in Singapore remained in the unhealthy range as operations were paused. Data from Singapore’s National Environment Agency showed 24-hour Pollutant Standards Index readings between 118 and 155 on Monday evening.
Regional monitoring stations recorded the highest concentration in the central and western districts at 155. Eastern areas registered 139, southern sectors measured 122, and northern districts reported 118.
Impact on Business Travel Corridors
Subang to Seletar provides an alternative for executive and short-haul business travel between the two capitals. Halting the route pushes passenger volume back to Kuala Lumpur International Airport and Changi Airport.
Turboprop operations at secondary city airfields face tighter weather and visibility minimums than major hubs equipped with advanced instrument landing systems. When visibility drops, regional feeder links take the earliest schedule cuts.
Next Steps for Passenger Operations
Operations teams continue to monitor visibility along the corridor ahead of the scheduled October 15 resumption.
Plans call for restoring the six daily return services once air quality clears minimum safety thresholds at both airfields.
