Alitalia routes, 1973
This suite of maps, from a route map booklet, follow general air ways. We’re not a huge fan of this style, travelers do not necessarily need to know what air ways their flight will take as much as they need – or are interested – to know what routes they fly. Still, these Alitalia maps are relatively clear and easy enough to follow.
