Is there a simple way to procedurally determine how many flights are flown between two countries on a given day? Maybe even get an inbound/outbound break down?

I consulted the FAA data site (https://www.faa.gov/data_research/aviation_data_statistics/) but I didn't find anything promising. I was also considering scraping flight radar (https://www.flightradar24.com/) but is a somewhat complicated endeavor. Is there a simpler solution?
