Mstr Caution
Qantaslink is part of the Qantas group, but separate companies, anyone who starts with qantaslink is employed by either sunstate airlines or eastern airlines and gets a seniority number with that company. There is no arrangements in place to transfer from any Qantas group company to Qantas.
Cadets who are employed by qantaslink effectively have two seniority numbers one of which is for a company who has not employed them yet.
