I'd just add that CO has never taken lightly to competitors encroaching on its turf at EWR. They practically ran JetBlue out of town a few years ago, I think they only have a few flights now to Florida.

It wouldn't surprise me to see COUA add another flight EWR-HKG to try and prevent CX from gaining much share. They have more flexibility to do so as a combined carrier from a fleet perspective. Not sure about the regulatory/slot aspects though.
