28/03/93 there was a timetabled interchange of aircraft between Qantas and Australian so that could be the date we are looking for.
On that day VH-EAM operated TN530/461/42/45 SYD-OOL-SYD-PER-SYD
VH-EAN operated TN8 SYD-PER and VH-TJK operated QF21/22 MEL-SYD-MEL.
In 1992 there were Qantas aircraft operating TN flights but on an ad hoc basis.
Agreed FBF.
Clearly remember departing a 762 operating as "Australian 8", not sure if this was the call sign used or reverted to the A/C rego as it was at the time.
The date I'll take your word on.
