Duplicate flight schedule details

When i query “filghtsScheduleDetails” method, it returns few duplicate records like below


Here aircraft type,arrival time,depature time,origin and destination are same but actual ident and ident are different.
I am confused to identify whether this data belongs to same flight or multiple flights.
What is the difference b/w ident and actual ident (they are only different fields in above data)?

If the data belongs to same flight, which record(original flight info) should i need to consider?. Could you please explain it clearly.

Those are all code share fights that are listed as different identities for each of the partner airlines, but operated by the onel airline in the partnership as the actual ident.
