On-time departures are calculated by checking if a plane has taken off within 15 minutes of their scheduled departure times, the report said.
Experts cited increased flight traffic due to newly added flights from China, Europe and the Middle East, in addition to bad weather during the winter, as reasons behind the low ranking.
Noticeably, Incheon airport shows poor on-time departure records during the cold season due to foggy weather. On Christmas Eve, foggy weather delayed 239 outbound and 309 inbound flights, and several flights were canceled outright.
The report showed that Incheon Airport usually has a 70 percent level departure performance during spring and summer.
Every month, Flightstats puts together a list of the international airlines and airports with the best on-time performance records.(Yonhap)
