SINGAPORE Airlines said on Wednesday it will raise its fuel surcharge on SIA and SilkAir flights by US$5 (S$6.8) to US$20 from May 12 due to sharp increase in jet fuel price.

The new surcharge will go up from US$30 to US$35 for flights between Singapore and Asean cities, from US$130 to US$150 for flights between Singapore and the United States and Canada and from US$80 to US$95 on all other flights.

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

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

Oil has shot up to over US$140 per barrel.
