Routes data for specific Airline

Could you please help me with routes data. How can I get all routes for specific Airline, for example, WizzAir (WZZ, W6) ? I’ve checked all requests for XML 3 but didn’t find a necessary one, that can return such information.

Can you clarify by what you mean when you say “route”? Do you mean just origin + destination for each flight, or do you mean navaid routes used by pilots to plot the track of the flight?

Thank you for the consideration. I mean just exactly " just origin + destination for each flight".

Look at the AeroAPI ✈ Version 3.0 - Flight Status API / Flight Tracking API / FlightAware API - Commercial Services - FlightAware function
