You didn't read my post... you just made up what you wanted to hear and answered that.
You asked why passengers like me would choose to fly nonstop as opposed to fly with stops. And there are many reasons why I would choose that. But according to you, I am wrong for having my own opinion.
It's not an argument against choice... it's a prediction that it will inevitably fail. People don't want to take a 23 hour flight. There is simply a limit to endurance there. Hell, here in the UK you've got loads of people who refuse to fly more than 2 hours.
Of course it is. You outlined all the preferences you have including using Singapore Airlines. Therefore Qantas Airlines should never create a flight you would not take. Everyone should have less choice because of your preferences.
There's just not enough people willing to suffer that much to make this program commercially viable.. that means they'll have custom planes that are unprofitable on any route... which means QANTAS will have it's hands out yet again for government money (after doing all they can to kill competition in the Australian domestic market).
So I should believe you over Qantas that is doing feasibility analysis. But again, Qantas should not try because you said so.
If anything, you're arguing against choice as we'll have to force people to take flights they don't want to take in order for this not to fail. First to fall will be the PER-LHR flights as you're flying from nowhere to somewhere (Perth to London if you're too lazy to google an IATA code), the only reason you'd take this flight is if you're going from Perth on to another city. Perth is literally on the arse end of nowhere.
What are you talking about? That happens now. To leave Australia to London requires stops in places you may not want to stop. Also you do know that multiple airlines exist, right? If Qantas creates this flight, you can still fly your Singapore Airlines with a stop in Singapore. There are multiple airlines you will be able to choose if you want to stop. You are treating Qantas giving other people a nonstop option as them taking away your option that you would never choose. Your entire argument is everyone should make your choice.
