The revenue management systems for flights in/out of Australia have gone crazy over the last few weeks. All sorts of amazing deals are popping up as the airlines individually wake up and catch on to what is happening. I haven't seen things this crazy for years.
Count on more surprises and turbulence (no pun intended) over the weeks to come as various airlines realise that they have been left behind in the game. The Emirates/Qantas linkup, and the games played by the clever players, have really shook things up.
