Thai Airways International announced Saturday it would increase its fuel surcharge on some international flights by US$10, due in part on the rising cost of jet fuel. Wallop Bhukkanasut, the airline's executive vice president for commercial affairs, said in a statement that the new rates would apply starting Sunday. The surcharge on routes between Bangkok and Auckland, New Zealand, would rise to US$60 from US$50. On routes between Bangkok and New York and Los Angeles, it would increase to US$50 from US$40. In May, Singapore Airlines announced a fuel surcharge increase for the second time this year.
