Schedules seen in work today seem to indicate 8 weekly Cathay Pacific from mid April.
4 weekly B77W as currently operating, but, 4 weekly A350 added too.
Wed, Fri and Sun sees the A350 bring the CX357/358 schedule up to daily, but also an additional Monday evening flight added too, with 1650 arrival and 2015 departure from MAN.
Obviously to be confirmed.
