I'm looking at viewtrip for an upcoming trip, and I noticed that the flight status is not Confirmed (HK) for all flights. I think it might be a schedule change, but I'm not sure.

Three legs are HK, so I'm not concerned about them. However, one flight shows Unable (WK) for the flight I booked at the times I reserved, and Confirmed (TK) for a different schedule. Does this combination require any action on my part? Am I interpreting this correctly as a flight schedule change? If so, I hope JK will let me change that flight to something more convenient. However, ITA still shows the original flight time, and no flight at this new time.

Note: even JK's own web site does not show a schedule change, but Galileo and AAA (the travel agent) both do.
