4 out of 12 A330s will receive the new F class as well for medium haul routes.

The airline’s A330s are used on short-haul and medium-haul routes such as between Hong Kong and Bali, Cairns, and Surabaya. They currently carry 311 passengers in two classes. The A330s with the new First Class cabin will have 8 seats in First Class, 32 in Business Class, and 211 in Economy Class. Those with the new First Class cabin will serve medium-haul routes.

Hopefully the J class will upgrade to the current international J class standard of fifty inches...
