NZ99D Guam-Narita - any insights?

I see that at present (9:30pm) there is a flight NZ99D flying Guam-Tokyo.

Any insights to this flight? Diversion? Tech Issue? Charter?

The suffix D is commonly used to designate a delayed flight and avoid callsign conflict. ICAO can explain it better than I can:

When a flight experiences a significant delay (i.e. 24H) into the next day, there is potential for two FPLs to exist with the same callsign. To alleviate this, airlines might append the suffix “D” in Item 7 of the FPL after the flight identification.

This is common practice among many operators in order to:
  • Distinguish from the same call sign flight operating the next day
  • Retain overflight permissions associated with aircraft designators
  • Maintain commonality with passenger notification systems

This practice however is not “standardised” however and may lead to confusion between both operators and ANSPs where flights may need to “change callsigns” as they progress in their flight.

In other regions, States may require other indicators. For example the suffix “X” when delayed by 24 hours and “Y” when delayed by 48 hours.

I'm on the flight that got delayed 24 hours. Not super impressed with communication, I got no email or message at all. Luckily my partner did so we got alerted half an hour before our bus out to Narita!

Business is 1/3 full at best, and PE is apparently half empty, with economy very full. People in premium cabins mostly opted to find alternative routes home according to my flight attendant.
