heard it's due to surplus of Cpt on 330 fleet. Practically if one can go straight to the left after 5500K e.g. Wizz or Ais Asia and there's only 320 upgrade going on in QR, the question of to go or not to go is the one. The difference could amass up to half a year. All a matter of trust, I suppose.
Don't take it personally take it on the rocks!!!
