What's up with B-18210

…just checked to see where it was…and result is mysterious, or not…?

(It seems to end in mid ocean…I hope it’s just a case of missing information)

As shown below map:

At least part of this flight occurs outside of FlightAware’s primary service area. Learn more about FlightAware’s coverage and service areas here.

…and now I can answer my own question since I just watched it land here at LAX (around 5:15pm) – and this is a bit surprising…
Unless there is another plane with the same “dreamliner” livery, I saw it land here on the northern side…

…and that would have been within the FlightAware coverage and service area…

…and this morning I can see that it departed from LAX last night, but that there is no record of it ever arriving : )
(…at FlightAware – the LAX website would show both, but it’s hard to check because they don’t allow back-checking anymore, for whatever reason)
