Well, I guess partially thanks to this offer I was able to book a trip to Australia (MXP - MEL - CDG) for a very good 632 EUR, in Economy.
I think flights to Australia don't come much cheaper :-)
They certainly don't.
About 30 years ago I enquired about flights from the UK to Australia, and I was quoted approximately £1000, equal to approximately EUR 1140 today, for an Economy return. In reality, you paid about EUR 500 less, and that's without any allowance for three decades of inflation.
