I'd call that EXCEPTIONAL flexibility Mstr Caution, they have so much flexibility in what they can do.
Got an Aircraft broken down?
No problemo! Just whip one out of storage!
Maybe they'll decide to have a quick run to Hong Kong to see how the paperwork is all coming along?
No problemo! Just whip one out of storage!
Delays causing peoples flights to back up?
No problemo! Just scurry up some of those lazy inefficient Pilots sitting around of their own accord doing nothing and fly one out to pick up the slack a bit!
See? EXCEPTIONAL Flexibility I reckon. They should take them and have them posted in strategic locations all over the globe, just sitting, nay!! Crouching, like a Tiger!! Waiting to attack any problem that may confront the good ship Qantas and its merry group of followers!
