The whole deal's fairly interesting given that:
a) 'bus would've had to come up with some sort of compensation for the Rat and Qantas in any case would've needed some sort of extra capacity due to the late 380 deliveries;
b) the airframes that 'bus probably would've given to the Rat in lieu of the 380s (ie. 330/340 family) will now stick (thus they won't then be dumped into the secondary market, pressuring resid vals);
c) much of the tooling for those airframes is probably already in long-lead in the form of certain 340s now not wanted by Emirates (ok many detail differences, but long-lead stuff like frames and panels);
d) several 380 delivery slots have suddenly become available with the Hairy One deferring to 2013... (yeah, right)
All makes for attractive pricing on both legs.
