I personally think they will try and do just that.
Many people assumed (maybe not on here) that QR would be done when the blockade came in, but EY, with that market still totally open to them, are the ones bowing out. I imagine QR may go to 10 a week on the back of this news, maybe slotting in where the Chinese carrier doesn't. To go straight to twice daily when EY themselves were only 5 weekly is perhaps too much too soon.
