SINGAPORE Airlines (SIA) will raise the fuel surcharge by as much as US$6 (S$8.80) from Oct 24.

In a statement on Thursday, the airline said the higher surcharge is due to a sustained escalation in the price of jet fuel in recent months.

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

"Singapore Airlines will continue to monitor the price of jet fuel and keep the application of the fuel surcharge under active review."

The new surcharges, which will apply to Singapore Airlines and SilkAir flights, are as follows:

On regional routes, US$24 (up from US$22) per sector, for flights between Singapore and Asean countries.

US$104 (up from US$98) per sector, for flights between Singapore and gateways in the United States and Canada on a single-sector basis; and

US$67 (up from US$63) per sector, on all other flights.
