Of course, but the 789 promises even more range. And when it comes to multibillion dollar purchases, especially with a relatively conservative and safety-focused airline like Qantas, they're likely going to want to see how the 787-9 specifically works out first; hence the options and purchase rights contained with the firm order for the 789s. This served them well with the A380s, they would probably be losing bucketloads of money if they had eight more A380s on the property. Also, factors will be different compared to JQ with how they outfit the economy section (they probably won't do 2-4-2 and will do 3-3-3 like everyone else :evil

, and if they offer F or not on them (I hope they do, even if just one row of 4).
This isn't what I want of course, I want them to take more A380s

, love that plane.
