Suspect maybe might see something new when they pick the 772 replacement?
Last week they seemed to be throwing everything in the mix 787-10, A350-1000 and 777-8X. Though kinda doubt the 787-10 is an actual contender as its range is too small. Unless split the 772 replacement it with the 777-8x and 787-10. Use the 787-10 for the mid haul into South Asia, Aussie and Pacific. Then have the 777-8x when need the legs East coast US, South America, UK (only say as QANTAS is looking at SYD-LHR with the A350-900ULR and 777-8X)
