3 weeks to do the Jetstar ground school for cabin crew, not 3 days.
3 Weeks to do the full course perhaps. 3 days will have someone legally endorsed to be cabin crew on the aircraft. This is a strike-breaking style workforce, not a full service one.
And no pilots would not be allowed to operate with crew that haven`t done that course.
Pilots would have an "interesting" debate about refusing to operate with crew legally endorsed on the aircraft by Jetstar, be they temporary or otherwise. I hope the union is ready for it.
And I bet the punters where really p&$$#d off they got the 767 with the QF service at J* rates as opposed to the state off the art airbus.
No, we got lots of compliments. A number of them got business class, and the rest in economy with the full Qantas service for free.
Thats all besides the point - the reason Qantas was brought into this discussion was that the O.P was talking about strategic providing backup crew for christmas, when its completely unnecessary because whenever they have an issue big brother comes to dig them out of it!
