I recently subscribed to Starter pack of FlightAware and I found that it gives access to only FlightXML Ver3 and NOT FlightXML Ver2?
I tried accessing Ver2 apis and got Authorisation errors while for Ver3, it worked.
Documentation for Ver3 has lot fewer apis than ver2.
Some of interest not present in Ver3 are AllAirlines() and AllAirports() to get ICAO identifiers of supported ones.
Can you suggest how I can do a workaround on that or by what timeframe(weeks/months?) all those api(s) would be available for Ver3 also?
