I was last at BEG in 89. Not one of the worlds noteworthy airports even then, although it did have two old JAT aircraft in its small “museum” a Convair 440 and a Sud Caravelle. It would certainly figure for Boeing to open a service centre there as JAT has a fairly large 737-300 fleet as well as a leased 400. The last 727s and DC9-30s go this year and the sole DC10-30 is now based in Havana on lease to Cubana.
