Airservices Australia...Flex routes and Sydney curfew
The point I wanted to make in the first place, is that the "non-compliant" flights are penalized for reasons beyond their control. No widebody long-haul flights depart early...they get the wind component they get...they can't slow down much in cruise....
This will be the next brilliant ASA " "National Operations Centre" programme; a stretched, more circuitous "Flex" route to negate a favorable component so that they arrive on schedule.....oh, but wait, the NOC will require additional staff to implement this programme...Yeah! Ripper!
