XML3 data refresh rates

I’m curious if anyone knows the refresh rates for the underlying data data returned in the FlightCancellationStatistics and CountAirportOperations calls? Are they updated as data changes in real time or are they batch processed on a set schedule?

We’re just thinking of how often we should requery to effectively stay current with ‘live’ data.

The underlying data in FlightXML 3 is updated near realtime as new information becomes available. How many updates are possible daily will depend on the traffic volume and conditions at a given airport.

Translating this into a reasonable query amount will likely be based on what kind of refresh interval is needed in an application.
