I think it is quite clear that Hong Kong has a much better strategic positioning as a main regional hub in the region, but has Guangzhou the ability to, eventually, match Chap Lap Kok in terms of connecting importance? Is Guangzhou seen as a "secondary" and competing terminal, or purely an O&D airport?
Even though both airports are located nearby and they do belong to the same country, I think there's still has a psychological barrier between the two cities (thus, few intermodal and cross-border passenger exchanges). Am I right?
Would you have any comments about this topic or could suggest me any further reading?
