Apparently the QF reps are going berserk trying to drive sales. For this particular outfit who are a top tier QF reseller the share of international work that goes to QF is down to sub 20% of their total. Threats to remove the top tier status have been issued if they don't boost QF sales in both absolute terms and in terms of share of their overall sales made. The company boss doesn't particularly care, QF have cut their terms already and the long term utilisation of fuel surcharges to avoid paying commissions on full ticket charges has eroded any loyalty to QF from the sales force.
