The pilots that joined JQ around the ‘14-15 era are in the sweet spot. 3.5 years to the wide body. The 10-13 joiners needed 4-6 years.
The ‘09-10 joiners are getting SYD/MEL commands now. The late 08-09ers waited 9 years, the 06-08ers waited 4.
Interestingly a SYD widebody FO is pretty much as senior as a SYD captain. I must say, I’d stay on the widebody too.
The 10-12 joiners will need 8-10 years to command. The 13-15ers probably 6-8 years and then after that. Good luck! It’ll blow out to 12+
As has been mentioned above, QF would be the best option salary wise, base and fleet right now in Australia.
The attraction to JQ was a fast left seat and a 250K+ job. You’d earn far more money now at QF before command and have lots of lifestyle options.
