First, Sorry for the Route/Road mismatch! In fact is it Road, i checked it before.
IATA PK -----------> ORIGIN PK +FK
spacee -----------> DESTINATION PK + FK
So IATA is a String of an Location/Place and Road has a StartPoint (ORIGIN) and an EndPoint (DESTINATION). So Road has a double relation with Location.
The idea behind this structure, in Java, is to know from one Road, for example, which the Details of the Origin/Destination from type Location are without using SQL and just work with Java classes.
