SINGAPORE Airlines (SIA) will increase its fuel surcharge for tickets issued from March 26 due to escalating jet fuel prices recently.

The new surcharge increases of between US$4 (S$5.57) and US$7 will apply to SIA and SilkAir flights.

On regional routes, the surcharge will go up from US$26 to US$30 per sector, for flights between Singapore and Asean countries.

For flights between Singapore and gateways in the United States and Canada on a single-sector basis, it will be up from US$123 to US$130 per sector, and on all other flights, it will be from US$75 to US$80.

'The new surcharge is subject to official approval in some markets, and some local variations may apply where regulatory approvals dictate,' said SIA in a statement on Thursday.

'The adjustments will offer only partial relief of higher operating costs arising from increases in the price of jet fuel.'

The airline said it will continue to monitor the price of jet fuel and keep the application of the fuel surcharge under active review.
