TPE-NRT
Today (11/26) my TPE-NRT flight was canceled, but they got my on Air China in time. 2 days ago the NRT-TPE flight was also killed (I got on Delta). I just discoved that this deleted my return flight, so now I'm in a middle + seat on a full NRT-LAX return.
At least this convinces me of the value of 1k, as other pax didn't get put on other airlines. Hopefully I'll get miles, as I'm barely making 1k this year.
