I'm sure Airbus will be happy to sign a contract with QF that allows for "flexibility" - for a small fee. They were quoted in Flight last week saying they effectively "over-sell" their production because hey know people will delay, pull out etc - the manufacturing equivalent of over-booking flights. I'm sure they figure that point-to-point has received a boost from intermediate stops closing during the virus at very short notice. People suddenly routing via Darwin (QF) or the West Indies (Air Tahiti Nui) will be more interested in non-stop in future.....................
