The Flying Kangaroo currently serves the city non-stop with five weekly superjumbo and two weekly four-class B747-400 services.
These will soon be replaced by a daily three-class B747-400 service. The change is being made in order for Qantas to upgrade its Dallas flights to the A380.
As a result, there will be a complete absence of first class on the Sydney to Hong Kong route from September. Currently, both jetliners offer 14 seats in first class — a total of 98 weekly.
In addition, capacity loss will also be felt across other cabin classes. The number of weekly business class seats will fall to 364, down from 424, while economy class will also see a loss of 440 seats. However, the number of premium economy seats will increase by 41.
It is likely that the three-class B747 are only going to be deployed for a temporary period, as Qantas has already announced that it will operate the A330 on the Sydney to Hong Kong route, once the aircraft has been retrofitted with the new seats unveiled last year.
In addition, the Flying Kangaroo intends to expedite the retirement of its fleet of non-reconfigured B747s, as part of its A$2 billion (US$1.7 billion) cost reduction programme.
