I saw instances where a particular flight (e.g. HM*) is not displayed in the flight list is returned via the following endpoint (all flights are “Arrived”):
https://aeroapi.flightaware.com/aeroapi/flights/HM*
Is this occurrence expected to happen occasionally?
Could you explain a bit more detailed the issue you are seeing?
I’m using https://aeroapi.flightaware.com/aeroapi/flights/HM5
around 12.28 AEST (Dec 7 2022). The live page (screenshot) shows that the flight is EN ROUTE, while all the responses in the API have “actual_on” set to a value, which means all of them have arrived.
Could you share the results? I show an actual_on as of the time of the synthetic arrival, which Id be interested to see what would have been there previous to that. "actual_on": "2022-12-05T05:47:44Z"
This is the corresponding API response at that particular point of time:

Some of those flights are “position_only”, meaning we aren’t receiving flight plans in advance for them and so we detect them only once we start receiving positions about them while en route. It’s possible that some of those flights were only initially tracked by their aircraft registration (VH-YXG) and only became associated with their operator callsign (SEY5 or HM5) once the pilot starts communicating with ATC. Depending on when you loaded the page/API and when that callsign association happened, it might not have been initially visible by callsign.
