Air Jamaica was the national airline of Jamaica and headquartered in Trinidad and Tobago.  Air Jamaica used Douglas DC-8s for a large part of the 1970s, along with the McDonnell Douglas DC-9 and Boeing 727 which came toward the end of the decade when the government bought out Air Canada’s share. Air Jamaica became Caribbean Airlines in 2011 –  Thanks Mark EwingChow & Patrick Boulton for the images
