Passengers flying between Borneo destinations should be ready for schedule changes as AirBorneo reviews operations amid Sarawak's worsening haze. The airline said some intra-Borneo flights may be retimed or cancelled for safety reasons, with further announcements to be made if scheduled services change. It urged passengers to check its latest updates before heading to the airport. The warning comes as hazardous API readings spread across Kuching, Serian, Samarahan, Sri Aman and Sarikei on Tuesday. That does not mean every flight is disrupted: the advisory describes possible changes while assessments continue. Travellers from Kuching should keep their booking details handy, allow time to check for notices and confirm the status of the specific flight rather than rely on general haze reports.
