Jetset,
Do you honestly think CX wanted tp pay A-Scales after 55?
They must hate it. The truth is they have realised from trheir lawyers that they will have to pay it on most bases and that they have to change the RA. The alternative is to still have 55 in Hong Kong only which would mean the bases would be shut off for years to anyone from HKG. It wasn't part of a "pot" of money to be negotiated. It was pragmatically saving legal fees.
