13 typhoons from July 1st to September 20th and their impact on the operations of 28 major airports in Mainland China, Taiwan, Hong Kong, Macau, Japan, and South Korea was the subject of a recently released study by Variflight.
The study shows that typhoons caused cancellations of over 15,000 flights and led to the lowest on-time departure rate of 4.47% at Naha Airport, while typhoon Jebi and Mangkhut had the most severe impacts on airports in this region.
Typhoons and tropical depressions are a common occurrence in Asia-Pacific during summer-early fall. This year, only in the course of 2.5 months, the region was hit by 13 typhoons and strong storms. Even though not all of those typhoons were as destructive as Jebi or Mangkhut, they still brought about disruptions of transportation including flight cancellations and delays.

1. On-time performance (OTP) rate
2. Average delay time
3. Flight cancellations
Additionally, typhoons were analyzed according to their influence on flight disruptions and cancellations.
Lowest departure OTP rate: 4.47% – Naha Airport (OKA)
