I use FlightXML3 requesting Palma de Mallorca airport (LEPA):
https://{username}:{api-key}@flightxml.flightaware.com/json/FlightXML3/AirportBoards?airport_code=LEPA
The response I get is:
{
“error”: “Invalid value "" for number input.”
}
There is plenty of data in the live version of the homepage:
http://flightaware.com/live/airport/LEPA
Why can I not get data for this airport?
