ALM Antillean Airlines Network, Date Unknown.

Via this Dutch Caribbean website comes this vintage route map of ALM Antillean Airlines. The image is undated but does not seem to be contemporary with the end of the little airline's life in 2001, so could be from anywhere between 1985-1995, although the airline had its origins in 1964. 

The "Dutch Anitllean Airlines" logo sits over the mid-Atlantic ocean, the same light blue as the nautical  labels and coordinate lines. The airline's routes spoke outward from the ABC islands, with three separate services to New York, one via St Maarten, and two to Miami via Kingston, Jamaica. Port-au-Prince, Santo Domingo, and San Juan are also served. 

These tiny Dutch constituencies hug the massive South American coast, and likewise ALM's routes seem to skirt around the territory, particularly the southeasterly service which terminates at the Dutch-speaking Paramaraibo, Suriname, via Port-of-Spain, Trinidad and Georgetown, Guyana. Other, shorter routes pierce the mainland, linking major Colombian and Venezuelan cities with the airline's home airports, Queen Beatrix International in Aruba and Hato International Airport at Willemstad, Curaçao. 

BWIA: Caribbean Network, 1967.

A luscious vintage brochure from British West Indian Airways from 1967, when Barbados and Trinidad were in their first years of independence, and Antigua and other islands were still colonies of the crown.

Ruler-sharp red lines span the Windward Islands, connecting each to Barbados, with its direct service to both Georgetown and New York. Several straight lines terminate at Port-of-Spain to stretch across the brow of South America.

A dense web of island-hopping services across the Leewards includes Beef Island off of Tortola, with a number of lines ending at San Juan. Trans-ocean routes from Antigua branch off toward New York JFK and Miami, with a planned pan-Atlantic route to London Heathrow just in planning, "subject to government approval" (it was soon authorized). BWIA enjoyed decades of glory before sadly coming to an end on the last day of 2006, remade as Caribbean Airlines.
