How can find flight type

Hello FlightAware Staff

How can find it this flight is domestic and international.

What parameter retuning flight type. Because i cannot see the parameter to get the flight type.

This is very urgent Please help me.

Ex : LX455 is domestic and AIC191 is international. But how can find by API this is domestic or international.

You could use the AirportInfo calls in addition to compare the origin and destination countries.

But LX455 is from England to Switzerland. Why would that be regarded as domestic?
