Japan Airlines Corp., the nation's flag carrier, slashed China, South Korea and Hawaii flights after an earthquake and nuclear crisis caused a 25 percent drop in its international passenger numbers.

Cuts to Tokyo Narita airport operations starting April 6 include halting Hong Kong services, halving Beijing flights to seven a week and paring Honolulu to 14 trips a week from 21, the airline said in an e-mailed statement today. The reductions will last until about April 27, it said.

The airline's domestic loads have also fallen 28 percent since the March 11 quake compared with a year ago, President Masaru Onishi told reporters in Tokyo, as concerns about radiation leaking from a nuclear-power plant and power shortages damp travel to the capital. Singapore Airlines Ltd. has already announced Tokyo-flight cuts, while Qantas Airways Ltd.'s budget unit Jetstar has moved some services to Osaka.

Japan Air also cut services to Shanghai, Seoul, Pusan and Taipei. It will continue flying to Hong Kong from Tokyo's Haneda airport, it said.
