And Big Brother's Head Office accounting practices. Tell me, how much money does JQ Intl actually make from their 11 B787's? You won't find it in the Annual Report.
It would be interesting to compare this to what profit they might make if deployed as a domestic 767 replacement on golden triangle for peak services (in mainline colours). As has been mentioned previously, narrow body services are chockers and replicate resources when multiple flights leave at the same time. And that's not counting lost revenue for potential pax who miss out due to no seats available. The 788 is used widely in Japan on peak high density domestic services.
