SearchBirdseyeInFlight supports IN operation for fp?

Trying to hit SearchBirdseyeInFlight using {in fp {IGO741-1565757979-airline-0580 AIC30-1565738100-schedule-0001}}.
I have passed 2 flightIds, and it is returning NO_DATA no data available, if i only put single flightId, then it returns data.
Does SearchBirdseyeInFlight , FP supports in ?
