so you must live in a bubble like in public service or work for a bank. There are going to be many more flights cut due to Corona/economy. Only question is how deep & how many Qantas staff get told to go on holiday for months. Aren't some staff casual or on contracts that might not be renewed ?
There's a lot of water under the bridge for the economy between now and the launch of sunrise. Have you a crystal ball as to the demand between Sydney and London in 2022 or 2023?
There is definitely a possibility that due to economic circumstances or economics of the flight itself, or both, that the project won't go ahead. But if they do launch it will be full scale ahead, daily (or close to) , not just 2 days a week (other than perhaps during an interim period whilst they wait for aircraft deliveries).
