Personally, I think the downgauging of J capacity is a mistake - it is very difficult to get last minute long haul J on anything that is not operated by the 77A these days - with Australia being the most challenging - at any price. A couple weeks ago, Zac Purton and James McDonald had to cancel their trips as the only flight that would allow them to ride in both SYD and HKG the same weekend as booked out a week in advance and CX was unwilling to help. I'm not famous, but I've also experienced the same issue and had to fly with another carrier, or worse, HX.
