So ATC want the mines to rewrite rosters just to suit them and account for their lack of service delivery. Maybe we should get a decent ATC system/rules/airports. Maybe that might help the issue. And it's not like they haven't seen this coming. WA air traffic growth has been predicted for years, yet noone in power wants to change anything.
Meanwhile Gatwick airport moved double the airport movements of Perth with one runway. Places like Van Nuys, Boston which have old airport setup with close runways etc managed to move 2-3 times the traffic of Perth.
Maybe Greg should own the problem and start solving our aviation infrastructure problems rather then getting on the ABC and telling his customers that they have to change their travel plans that they pay for because his systems aren't good enough.
