RJGG is going back to mainline next year. This is in the latest 3 year plan.
Nagoya is not a 'holiday' port. It is now and always has been a business destination. Pulling J class out cost QF millions per year via the loss of the Toyota contract.
None of this is the fault of the hardworking AO cabin crew who I have personally found to be excellent.
On the upside for AO, a senior manager recently told me that when services to Pek recommence (next year) it will be done by AO.
Pvg will remain mainline as business class is regular overbooked by full fare payers.
