additional 787 for 747 capacity replacement on J/BURG etc, as possibly A330 replacement.
787 won’t be going to Johannesburg, unless it’s coming back via Perth. It simply can’t uplift the payload out of Johannesburg.
I doubt the 787 is a viable A330 replacement unless the company can get the pilots to kill night credits, or come up with an alternative LH vs MH pay rate or something along those lines.
Either they’ve realised the 787 contract is too expensive to fly MH or they knew it a few years ago and bull****ted about the planned flying to get the pilots to sign on. Either way, reality has struck them and now they want the job done for less if the 787 is to start flying to Asia as a 330 replacement.
