Really? How does that work? Wasn’t it supposed to be a private flight? How could it be a commercial flight with fare paying pax if it exceeded every commercial flight time limitation in the regs?
The Frequent Flyer's were refunded their fare to participate in the flight.
There is a subtle difference between being "the longest commercial flight" and "the longest flight by a commercial airline"; something Qantas media people were in no hurry to point out.
