SINGAPORE - Singapore Airlines, the world's second-biggest airline by market value, said on Wednesday that it will raise fuel surcharges for tickets issued from June 24 due to the sustained increase in jet fuel prices.

The total surcharge now ranges from US$180 for flights between Singapore and the United States, to US$40 for flights from the city-state to other Southeast Asian countries, and US$110 per sector on all other flights, the carrier said in a statement.

The new levels will also apply SilkAir flights.

This is the third time this year the company has raised fuel surcharges, as jet fuel prices have surged 49 percent so far in 2008. --Reuters
