Political pressure from US President Donald Trump on Latin America has effectively severed Cuba’s access to its primary petroleum sources in Venezuela and Mexico.

While the rationing may not disrupt shorter regional flights, it presents a significant challenge for long-haul routes from countries like Russia and Canada - a critical pillar of Cuba’s tourism economy.
