Why does Cathay Pacific charge so much for excess baggage, compared to other airlines?
Extra Baggage Charge | Baggage - Cathay Pacific
For example, on an Economy London to Hong Kong Cathay Pacific flight, a second bag of 23kg would cost US$60 / kg, i.e. US$1,380 (HKD10,695). There appears to be no pre-booking of a second bag charge to lower the cost.
By comparison, on an Economy London to Hong Kong British Airways or Virgin Atlantic flight, a second bag of 23kg would cost GBP55 total (c. HKD660).
