Under current arrangements JQ crew must complete 2 years service before they can place themselves on the list.
The reality is however the list is so long that the people who make CP at present are from Impulse days so we're talking 6-7 years service. The list has to get through all the crews from Qantaslink days as well before it will ever reach a "pure" JQer. Possibly in the year 2497
.
Hope that clarifies.
