Had one of my regular corporate pax shift from SYD CGK nonstop QF J class to SYD SIN CGK F class on SQ - about $200 dearer and a good option.
These threats of strikes etc have good basis, but they do damage the base you are standing on. The media doesn't help either in he way the interpret what you have said for maximum effect.
No criticism at all from here as I have no right to, but if you do not have information of the effect then you cannot evaluate what is going on.
Best all
