I don't think JM
flew the 707. They did have the DC8s in their fleet, and that is confirmed by the picture you posted.
Around 1964 the government of Trinidad and Tobago took control of BWIA. After that was in place the airline shifted its focus to the northern Caribbean and set up a base in Jamaica. Eventually the Jamaican government took over BWIA's Jamaica base and, with help from BWIA itself and later Air Canada, formed Air Jamaica. That explains the ties the two airlines had. The 727 you see there was actually one of BWIA's airplanes and not Air Jamaica's.
With regards to actually JM
727s, they flew with JM
even in the new / current paint scheme, and were gotten rid of when Butch Stewart decided to simplify the fleet, going with Airbus. JM
also during that time flew the MD83s.
That's all I know. The 747s I imagine were wet leased for long haul flights. There is also a big in the database of a wet leased BW
747 as well.
