Cathay Pacific have announced their next A350 destinations, which are Paris, Rome & Auckland, due to commence in October 2016. But no signs of Manchester I know the A350 for Manchester is going down to Gatwick instead but it hasn't stopped them launching Paris & Rome.
It's been commented that the A350 is no longer suitable for MAN, as the B77W now seems to be the right sized aircraft for above and below deck.
What's worth noting is that the next A359 destinations are direct B77W replacements with no frequency increase, so, a loss of capacity on those routes.
The fact CX feel the need to keep the B77W on the route should be seen as a positive, not a negative.
To the best of my knowledge MAN is still destined for the A350, maybe this time next year? LGW did not steal MAN's 350, CDG has 2 flts a day the 350 is a drop in capacity there, the 2nd evening flt is never full so makes sense. AKL was originally the inaugural long haul route for the 350, but things have had to change due to the delivery delays. The first one that arrived on Sunday is some 3 months late! So you can see a lot of reshuffling has had to be made.
