Fact - no one here has provided proof of these flight routes existence. Only conjecture. That is not evidence
Seriously? Way more evidence has been provided that the flights exist and literally zero evidence has been provided that they don't.
I mean there's even a video of a flat earther on the flight, in the cockpit, trying to show some nonsense about "level" flight and gyroscope stuff. Little did he know he was actually showing an RE flight and that it exists.
That video doesn't prove he was on 'x' flight route. Also, could be some REtard trying to discredit Flat Earthers by making them look like like a joke
Also, how does some random guy happen to get on the cockpit on a plane and take a video? That isn't even remotely allowed. Yeah sure, you get waken up by a sexy flight attendant and invited to go to the cockpit to talk about flat/round earth flight paths.
You only take this video as a proof because it suits your argument. You would never claim something like this authentic otherwise. It's a joke. It's sad that the round earthers have only this load of crap to point to and say 'SEE! THE FLIGHT IS REAL!'
Next time I'm on a flight, I fully expect the flight attendant to wake me from a sleep, invite me to the cockpit and start recording while I talk to the pilots. Sounds reasonable 
I had the same question as to how that guy got in the cockpit.
But all you have so far is your particular distaste for the airline industry, especially Qantas, as you feel they are over priced and out for profit over safety. I would agree with that though it doesn't seem very profitable to crash very expensive equipment and it's not very good from a brand perspective. But that whole distaste leads you to jump to the conclusion that they go to great lengths to fake flights and doing so to what end, gain, benefit? That's quite a leap in logic.
I don't have a video of someone pointing their iphone out a cabin window for the 12-14 hours duration of the flight. But there are plenty of videos of folks enjoying their high end accommodations on the flight, etc. They're presumably not trying to debunk a flat earth, just hoping to get likes and make their FB and Insta friends jealous.
As well, you're assuming, I guess, that anyone who purchases the flight never takes it. Or, in every instance, all direct flts are "canceled", always, and the customer is put on some insanely long connecting route. Yet they paid for a direct flight/shorter flt. Maybe we should be checking Qantas' yelp reviews for customers duped out of their direct flts.
Then you're pissed that there are more flt tracking receivers in Mongolia than Greenland. Kind of irrelevant. So I guess take up your displeasure with the fine people of Greenland.
And Wise's best reason for the flights to not be real is that no one would ever want to fly from S.America to Australia b/c of the language barrior...
Seems reasonable.
At a minimum there is a preponderance of evidence that the flights are real and flown by humans with humans on board. Conversely, there is zero evidence that they are fake.
