It's strange how there's so little known or speculated about the 787-10s compared to the months of speculation and snippets of info regarding the A350.
Looking at Uresh's 787 spreadsheet (
All things 787) BA's first -10 is Line number 956 which, at the current rate of 14 aircraft a month, puts delivery in January. In the past he had the estimated delivery dates listed up to a year in advance but he doesn't appear to get that info anymore so I'm just guessing. His sheets currently only go up to LN 1000 and ZBLA is the only one listed so far so the second will be at least three months later. I would have thought Routesonline would have had info on where the -10 is heading already but there's nothing at the moment.
