My 2 cents worth:
Most low cost carriers GENERALLY only operate a single fleet type.
I think its well known that a 717 can't operate SYD-PER or BNE-DWN. It's also well known that Boeing is trying to woo the Kangaroo into the 737-900X, and be the launch customer. They have approached Bombardier and ATR for RFP's on the regional replacements.
No insults intended at ANYONE but Qantas has quite a few aircraft types in the fleet as it is, and my humble opinion is that we will see a change with that.
I think it will be a 737 type operation. Going Airbus (A320/21) is a little late in the game plan to change horses..spares, engineering, training. As mentioned the options with Boeing are still plentiful.
A lot has happened in Aus aviation over the last 24 months, so I wont be suprised if ole mate Geoff makes some decisions that some may not like.
