In a worst case scenario, AC flies 24J every day to and from SYD although in fact the vast majority of time it is 30J.

From Nov to March they have double this capacity with the second flight.

So, from Nov to March they have average around 400 J seats per week to SYD.

Why can't AC make just 6 of those 400 seats available for Y,M advance purchase. They are not giving them away for nothing - but yes, they will be selling most of them at a discount for the eqivilent of a Y or M fare. -and only to their most loyal customers.

It is called 'good customer relations' or something equally foreign.

I still think that they don't really give a stuff.

MCM.

(they usually end up giving way more away for free at the gate anyway.)
