Imagine similarly two airlines were to say, "Look, Airline A, we'll take the route from LA to Chicago," and Airline B says, "We'll take the route from Chicago to DC, and we won't compete."
Supponete che due compagnie aeree dicano, "Noi della Compagnia A facciamo l'itinerario da Los Angeles a Chicago," E la Compagnia B dice,  "Noi prendiamo la tratta da Chicago a DC, e non competeremo."
