From a Penguin Random House review:
In this gorgeously illustrated collection of airline route maps, Mark Ovenden and Maxwell Roberts look to the skies and transport readers to another time. Hundreds of images span a century of passenger flight, from the rudimentary trajectory of routes to the most intricately detailed birds-eye views of the land to be flown over. Advertisements for the first scheduled commercial passenger flights featured only a few destinations, with stunning views of the countryside and graphics of biplanes. As aviation took off, speed and mileage were trumpeted on bold posters featuring busy routes. Major airlines produced highly stylized illustrations of their global presence, establishing now-classic brands. With trendy and forward-looking designs, cartographers celebrated the coming together of different cultures and made the earth look ever smaller.
A nostalgic and celebratory look back at one hundred years of passenger flight, featuring full-color reproductions of route maps and posters from the world’s most iconic airlines, from the author of bestselling cult classic Transit Maps of the World.
