The story goes that the first eight 787s have the low thrust pylon and will forever be cripples
All 787-8's have the same engine Pylon, all that is required is a relatively minor mod on the fuel control unit and some minor software upgrades but that will cost $$$$. Current mod status allows any current JQ 330 sector to be covered by the 787 but there will be payload restrictions on the longer sectors i.e. HNL.
