When compared to those other flight been regular services, can QF7879 be fair to compare as it stands out more than the rest! FYI it was less than 20 hours also!
I think a disclaimer needs to be added to any article related to the Boeing tour, that the normal tours have very high restriction from movement ability to no camera's allowed. Yes on the odd specialised tours they may be lifted, where possible. This will at least match expectation with experience.
