Domestic Skies: From Beijing to Honolulu

Shifting our focus to domestic routes, Beijing (PEK) to Shanghai Hongqiao (SHA) takes the lead as the busiest domestic route in China.

John Grant, chief analyst at OAG, sheds light on the findings, emphasizing Asia’s continued dominance in the global travel arena. “Asia continues to have the busiest routes in the world due to its popularity as a tourism hotspot,” remarks Grant.
