Yes, Hainan is one of the obvious white tails that may be some of the 5 B789s coming to LH. I doubt RC gave Boeing the seats during assembly as it was obvious that Hainan was already in BK at the time. The current guess is that it will be line numbers 887, 893, 898, 905, & 913. Those are all Hainan which later were assigned to Suparna and Vistara but then deffered but built.
