Gate information at Southend Airport

I’m writing an application specifically for Southend airport, and I need to know what gate the scheduled flights should be using. I understand that the gate allocations might not be known until around 24/48 hours before the flight is scheduled to land and also, they might change at the last minute.

My question is, using FlightXML3, is this information available before the flight lands or is it only updated afterwards.

From looking into the airport boards, it does not appear that we receive any gate information at Southend Airport.

OK, that’s good to know, thanks.
