Surcharges on short-haul flights will increase by US$27.50 to US$45 and US$71.50 to US$117 for longer flights, the Civil Aviation Administration (CAA) and transportation ministry said on Wednesday.

China Airlines and Eva Air confirmed that passengers will be affected by the hikes from April 7.

Ticket prices for domestic routes will increase by an average of around US$3, CAA director-general Ho Shu-ping told parliament.

“In response to international trends, prices often go up and down, so we need to make appropriate adjustments to reflect that,” Ho said.

The move comes as the war in the Middle East, and Iran’s effective closure of the crucial Strait of Hormuz, have sent crude prices skyrocketing.

A barrel of Brent oil, the benchmark reference for energy markets, which had fallen back below US$100 Wednesday, surged 7% to hit US$108.15.

Several Chinese airlines, including national carrier Air China, also plan to raise their fuel surcharges from Sunday.

Other airlines, including Air France-KLM, Air India, Qantas, and SAS, have raised their fares to reflect the increase in jet fuel prices.
