Singapore Airlines (SIA) and its low-cost subsidiary Scoot have adjusted schedules and cancelled at least 18 flights to and from Taipei, Tokyo, Seoul and Sapporo as Super Typhoon Bavi approaches Taiwan and eastern China.

A total of 16 flights scheduled for July 10 and 11 have been cancelled, including Scoot services between Singapore and Tokyo's Narita Airport, Seoul and Sapporo via Taipei, as well as four Singapore Airlines flights between Singapore and Taipei.

SIA flights SQ878 and SQ879 between Singapore and Taipei on July 10 have also been rescheduled, Asia One reported.

The airlines said affected passengers would be contacted directly with updated travel arrangements and advised travelers to check their flight status pages for the latest information, as adverse weather could cause further disruptions.

Passengers affected by the schedule changes can choose to be rebooked on another flight or request a full refund for the unused portion of their tickets, SIA said on its website Thursday.
