Not once in the year and a half working here have i been delayed by technical reasons when flying the Fokker, yet the poor bastards on that Airbus have been delayed or held overnight more than a few times. It would not surprise me one iota if it had already overtaken the Fokkers in tech issues.
VH-UFO-
The answer lies purely in the fact that there is only ONE A320. Im sure the Fokkers have gone tech numerous times in your year and half but you have failed to see it because everyone has worked behind the scenes to make sure a replacement is organised and the schedule is uninterupted. I thought we did a very good job on Friday night to get 200 people out and left only 40 before last light!
