AirlineFlightSchedules for past data gets empty result. json

I’m trying to execute the following json to get the schedule flight information but get empty result. Would like to know if I’m doing something wrong?

My query: Flight from LAX to SFO on VX0935 on 17-Sep-2014 ~09:15AM (I gave 2hr before and 2hr after on the epoch time)

the slot exists (future date example)

I’m not certain why specifically this wasn’t working, but in general you should expect AirlineFlightSchedules to not be as reliable for dates in the past.

This is a big issue for me. My requirement is to have past schedule date. How can I get past schedule flight in this case? What are my alternatives?
