I've lost track of the Cathay A350 orders, they ordered 900s then upgraded some to 1000s then late last year downgraded 6 back to 900s and then deferred some deliveries. But I think Spanners is right in that they will be lucky to have 5 1000s in use by Dec 1st. Presumably having announced the 1000 on the MAN route must mean alterations elsewhere on the network yet to be published (?) If the 1000 is unavailable- with seats sold then I wouldn't be surprised to see a 777 sub on some services.
