The rules sheet says that: "Where the applicable booking class for the lower class is not available ... Passengers travelling on DONE* Business Class Fares may book B class (except AA) or H class on AA".

Am I correct that means that I should be able to book a QF flight that has no J class and shows as: Y9 B9 H9 K3 M0 L0 V0 S0 N0 Q0 O0 G0 X0 E0 ?
