While most of what said above is true. New CC recruits at Jetstar are trained to the minium and the younger the better seems tobe the recruitment line. Three weeks ground school 15 days or 120 hrs and 4 Days line training. Thats it. With no real world experience doesn' t look good sometimes.
However in the case of this thread the CSM has over 10 years of experience and is a good bloke, he also asked the Captain of 20 plus years of Airline experience of his opinion and options.
No twenty year old making this call.
