I think you'll find QF has 'given away' most of their customer contracts as they have come up for renewal over the past 2 years after AJ said he didn't want them anyway...
The evidence seems to confirm that - not only for check-in staff but ramp and engineering as well. Every time a contract comes up for renewal, the Qantas "tender" is always so high that it drives previously loyal customer airlines to seek lower price contractors. I don't understand why the institutional investors don't investigate the actions of QF instead of accepting ongoing loss of revenue.
