I think Airways is a great company to work for.
Usually your first posting is as described above. Then, provided you're offered a permanent posting you can make a bid for any position. That's roughly how it works. If u get a consolidation contract because the tower u trained in is already fully staffed, they'll bounce you to somewhere you're needed. I could go on about how successfully I think Airways operate this system, but I can't be farked. if ur not an Aussie or a Kiwi youll have issues getting on the course as mentioned
