Well, I travel on business and leisure on Australia's domestic system, and have been doing so for some time!
Qantas is so-so OK to travel with, Virgin are also so-so OK to travel with, but I will not fly in an Airbus anywhere, which cuts out Perth trips (my home town) with Virgins A330s, and completely blacks out Jetstar and the other minor A320 players.
So, with this upgrading of Jetstar to Boeing 787, it looks like I will be able to try out their services, which will greatly enhance my choices!
Sounds good to me....
