I need for an application to count the number of flights between two airports for a period of time (ex: 2017/07/01 to 2017/08/01). I try to do it with RoutesBetweenAirportsEx, but I cannot specify a date with this function. Search functions are limited to 24 hours. Then, I think to use AirlineFlightSchedules and read length attribute of the data field to get the number of flights, but it gets a lot of information that I don’t need. Furthermore, this function seems to fail when having a wide range date like 2017/07/01 to 2017 07/30.
What would be the best way to get this information?
