AirlineFlightSchedules count total number of rows before query

Hello,

I am running the function AirlineFlightSchedules to get all the flights as of yesterday. But before doing a script that run 15 by 15 rows, I would like to know how many rows there is in total on this request :

api.service.AirlineFlightSchedules(1580256000,1580342400)

Is there a way to know in advance please?
Thanks

A global flight schedules request for a given day would have a result in the of 800k rows due to codeshare entries and take a while to return results with not additional filter conditions. This would be a case where filtering to an airport or airline would likely be needed to be performant.
