REDEPLOYMENT AND RECRUITMENT OF QCCA TO A380 (QAL and QCCA)
With the current planned arrival of another 4 x A380 by March 2011, there will be additional requirements for crew to operate on the A380. The Company has advised that by BP273 all QCCA crew in the BFA and FA categories in both Melbourne and Sydney will be transferred to the A380 to meet this crewing requirement. Furthermore, there have been a number of QCCA crew accepting opportunities with QCCUK and QCCD. Therefore, there will be recruitment of up to 3 classes of QCCA crew to back fill these transfers. It is envisaged these new recruits will eventually be transferred to the A380 by BP273.
