I had an aircraft change (from A359 to A333) which caused my assigned seat to be dropped (naturally). The Manage Booking on cathaypacific.com would not let me choose a new set (it reads: "We were unable to process your previous request. No further seat change is allowed"). The CX call centre in TLV is not the brightest one; is there a way to do it online? I'm a OWE and had no problem choosing my seats after the ticket was issued.
