Austraian Biz TravellerBusiness travellers with flights to Korea, China, Taiwan and Japan should check arrival and departure times with their airline following the eruption of Shinmoedake, a volcano on the southern Japanese island of Kyushu.
Closer to Shanghai, Taipei and Seoul than it is to Tokyo, the ash cloud from Shinmoedake has reportedly delayed flights in the region as airlines play it safe to avoid the volcano's plume.
Flights to Japanese airports are already affected by Friday's earthquake and tsunami, plus the following relief efforts. Most airlines are waiving change fees for flights to and from Japan for travellers who need to make different plans.
But a quick glance at the map shows that international airports in Beijing, Shanghai, Taipei, Seoul and Busan are near enough to be affected by Shinmoedake's ash plume.
