G-ZBJA's retrofit is progressing and should complete later in the month. The certification will require some additional time as it's caught up in the well-known Boeing-CAA/FAA/EASA brouhaha. I'm hearing May for entry into service, but no word on the route(s). I think it's better to plan it a couple of days out when it's certain. I also haven't seen any onboard maps / service details yet.
