CP Air: Worldwide Network, c.1983

The wonderfully random route network of Canadian Pacific Airlines in its classic CP Air age, when it was the airborne division of Canada's premier transport companies but not able to fly it's premier international routes. A unique collection of flights fan out to four other continents, two across the Pacific: Vancouver—Tokyo—Hong Kong and Vancouver—Honolulu—Nadi—Sydney, and one venturing south to the cone of Latin America: Mexico City—Lima—Santiago—Buenos Aires.

From the Alberta prairie, a transpolar route links Edmonton to Amsterdam, linking to a Rome—Athens route. A second trans-Atlantic flight from Montreal lands at Amsterdam, while a third European route also starts in Montreal, but leaps southward to Santa Maria in the Azores, then to Lisbon, Madrid, and connecting again at Rome. Paris and London are absent.

CP Air: Worldwide Routes, October 1978

The incredibly complex connectivity of the classic Canadian Pacific Air Lines route network in October 1978 is shown here in this blazoning vintage advert. Then operating as CP Air, the aviation arm of the Canadian conglomerate offered passenger services to 14 international airports on five continents from no less than five separate gateways across Canada.

Particularly key was the European gateway of Amsterdam, which lined to four Canadian cities: Edmonton, Calgary, Winnipeg and Toronto, although somewhat oddly not its primary airport, Vancouver. CP Air jets also departed Toronto for Milan, and Rome, with onward service to Athens from both Rome and Amsterdam. Rome and Lisbon, but not Amsterdam, were served from Montreal, which also enjoyed service to Mexico City. Toronto was also linked to Mexico City as well as Acapulco and Lima. Whether the continuing service from Lima to Santiago, finally terminating at Buenos Aires, were originally from Toronto or Vancouver is unclear.

CP Air also connected all its international gateways, except Montreal, to Honolulu, from whence it plunged far south to Antipodea. CP Air's Pacific operations, shown above, will be detailed in the following post.

American Airlines Hub Maps, 2002: Boston Logan

Boston has never been a true hub for any airline, other than a feeder to a handful of European airlines or a catchment for high-value local passengers. American's array in 2002 included more code-shares than mainline services, mostly long-range transcontinental runs; connections to hubs; and its flagship transatlantic routes, often on glistening silver B777s. Links via other carriers to Canada, Down-east, the Islands are shown; all of this intersperses at right, with Bermuda, New York, Paris, London, Halifax and Burlington shown in counter-clockwise arrangement from 4 to 1 as being equidistant from Logan. Islip, Ottawa, Vancouver and Chicago are all arrayed from 11 to 8.

American Airlines Hub Maps, 2002: Chicago O'Hare

Chicago O'Hare serves both as American's upper midland superhub to ferry domestic passengers from one side of the continent to the other, as well as a premium business hub for origin-and-destination traffic: Tokyo is at upper-left; a vertical row of ten European non-stops are at upper-right. Honolulu is at far bottom left, a smattering of Mexican cities is served, but the farthest into the Caribbean basin is the non-stop to the San Juan complex: travelers to Latin America must connect through Dallas or Miami.
