Inbound ID missing from FlightInfoStatus

In this picture the highlighted flight is about one hour from departing at time of search. the flights are organized in descending order on the departure time. the flight right below the highlighted one is the inbound, why is it missing? This search was done on flight info status by tail number N347FR

For performance reasons, FlightInfoStatus will stop including the inbound flight info for some results if you are requesting a howMany argument of more than 15.

This was without a howMany argument specified. But I just tried it again with a howMany of 14 and it still didnt have the inbound ID. Could it be because 2-3 days elapsed with the plane on the ground before FFT770?

Yes, that’s likely the reason. We only classify inbound flights that have a previous departuretime of less than 48 hours.
