FlightInfoEx returning "no data available" for all Virgin flights

I put in a flight number (ex: VRD1713) and get no data. On the website, a search for VRD1713 shows data from 3 or 4 weeks ago.

So there IS data, although old data, it exists. What’s happening here?

FlightXML does not return data older than 2 weeks, by design.

“FlightInfoEx returns information about flights for a specific tail number (e.g., N12345),…The howMany argument specifies the maximum number of flights to be returned… The oldest flights searched by this function are about 2 weeks in the past”

So this means that no flights older than 2 weeks are returned? Why isn’t there recent info available for Virgin flights?

EDIT: Also, if you could answer for me if there’s any way to get data that’s over 2 weeks old through FlightXML, since its available on the website.

Virgin America (VRD) was merged into Alaska Airlines (ASA), and no longer operates independently.
