Just to put thing's in perspective; The post 1993 salary ('B' scale) increase is in the right direction although this is still well below 'A' scale salaries. The pre 1993 ('A' scale) salary increase is actually a removal of the third year of salary cuts. This will not be a big win for CX crews.
In fact the offer was announced to pilots by the Director of Flight Operations as a "this is what you are missing out on" letter.
The offer has been withdrawn by management. Swire managers do not negotiate in good faith. End of story.
