Yep, looks to be the case. Also now makes sense too that the two tails that were showing originally being done on 7 & 8 March (using the "expected" 44 days) would likely be a week later, Wonder if will see another tail heading to XMN this week also, to swap out the "other" one that has originally shown as coming out ~8March? considering these went in BEFORE Asian New Year celebrations, and would not be at all surprised if the facility was closed or at very reduced operations for that week of 1 Feb, which was after they arrived. Although as a 787-10, wouldn't this have already come out originally as a 1-2-1 up front? And not the 2-2-2 layout?
Then again, I guess on this one, if its the 787-10, Guess maybe it would not have United PremiumPlus but only EconomyPlus????
Not sure. Certainly no UA equipment expert, so if someone can enlighten, that would be good to know.
