SYDNEY (Kyodo) Qantas Airways Ltd. will increase its seat capacity for flights to Japan starting in July due to an increase in demand, Chief Executive Officer Alan Joyce said Thursday.

Australia's national carrier currently flies daily between Sydney and Tokyo using Airbus A330-300 aircraft.

Starting July 5, Qantas will begin operating larger Boeing 747-400 aircraft on six runs each week, increasing capacity by 115 seats per flight, Joyce said.

He attributed the increase in demand to a rise in the number of Australians traveling to Japan for leisure and to visit family and friends.

"Japan is also a key gateway for Northeast Asia traffic, particularly Korea, so this additional capacity will allow Qantas to grow this market," Joyce said.
