Have a look at which fleet and base 6 of the 7 guys are currently from!!!
With the 170s going, 1 airframe per month from june (or so im told) and with the majority of the 170 flying out of SYD, I am of the opinion that these appointments are to assist in managing a looming surplus of ejet crew in SYD.
The company looking after their own needs before considering engagement once again..... Tis no surprise
