Jet fuel prices pushed past a new record in the past week, hitting $3.685 a gallon in New York and soaring on other world markets as air carriers moved to hike fuel surcharges again.

The fuel prices for airlines in Singapore, which have lagged behind other markets, moved past $3.33 a gallon by April 11, according to the U.S. Energy Information Administration, marking an increase of more than 10 percent in just two weeks.

Prices in New York ended the second week at $3.647 a gallon after slipping back slightly from the all-time high, but that still meant jet fuel prices have grown by nearly $1 a gallon since the start of 2008. The New York price last week was just short of $2 a gallon higher than jet fuel cost at the start of 2007, less than 16 months ago.

British Airways announced Thursday it was raising its fuel surcharge to $1 a kilo.
