Search flight with ID + Start Date

FlightAware AeroAPI
1

Hi,

I need to know the request for search a flight with ID + Start Date.
The information on result must be exactly flightInfoStatus.

I tried to use AirlineFlightSchedules for use fa_ident in the flightInfoStatus request.
But i have this message “Your account subscription level does not have access to AirlineFlightSchedules”, how we can try this way ?
Are you an other way ?

Thanks for all

Mickael
