34 years to command a QF A380? That's an interesting lie.
QF invented Jetstar which then took all expansion for 12 years, and their idealogical bent was to deny any QF pilots the opportunity to transfer for upgrades, etc.
Current projections, due to the missing cadre the lost decade caused and upcoming retirements are three years average S/O (with some pilots getting 737 F/O within a few weeks of joining).
A new joiner can probably expect 6 years as a 737 F/O before becoming a widebody F/O and then narrowbody command a few years later. 737 captains can educate their normally aspirated (no mask required) children and afford a 7000 sq ft joint within an hour of their base. Note that's seven thousand square feet.
Seniority is honoured, and change of fleets, even within rank, is not limited except voluntary downbidding is discretionary.
Sure it'll take longer for a widebody command...maybe 20 years give or take. That's the nature of legacy carriers with a large domestic network.
QF will probably be locked into a cyclical hiring pattern now that they have set the stage that way. My estimates are only true for people being hired in the next two years. Be guided accordingly:/
