That sounds believable if we consider that Bain killed off TigerAir, the ATR fleet, most NZ flying pretty quickly (easy to justify with Covid restrictions anyway), the E190 fleet had already been retired (as hangar queens or just bad leasing rates we might never know but other airlines manage to profitably fly E190s). They kept the mainline B737 operation and I am wondering if it was the lease costs of the A330 fleet that sent them away into storage. Remember A330s were planned for HGK just as the initial riots and political instability hit Hong Kong. And the B777's were owned outright but of course not useful with international borders closed from 2020 onwards. Is that correct?
Without Covid, the A330 ops to Japan in an Olympics year should have made money, if the leasing rates weren't so stupid. As did the B777 transpacific operations before Covid.
