Singapore Airlines will cut the number of flights to some Asian cities in response to falling demand.

The airline said in a statement that it would reduce the number of flights between Singapore and several cities in Asia including Penang, Ho Chi Minh City, Seoul, Osaka, Bangalore and Chennai. It will stop flights to Amritsar in India.

"Other changes will be made on an ad-hoc basis where demand requires," it said, adding capacity adjustments will be made quickly where demand falls.
