(And no, this well precedes the pandemic). Even in today's supposedly ultra-globalised world, there is not ONE direct flight between anywhere in Latin America/Caribbean and anywhere in the Indian Subcontinent, and only from Havana and some Brazilian cities are there direct flights to parts of Africa (Angola, Cape Verde and Ethiopia, principally from Sao Paulo). Further, within Africa only Egypt, Ethiopia and Kenya have direct flights to India, while the other countries in the Subcontinent have no flights to Africa whatsoever. And let's not even mention the Pacific Islands, which can only really be reached via Australia or New Zealand (which themselves only have direct flights to a small number of countries).
And even within the Americas and Africa in particular, the options can be extremely limited and difficult, e.g. try booking a flight from the Cayman Islands to Paraguay, or Sierra Leone to Burundi. We in the West may take it for granted that we can travel to most places almost literally with the click of a button, but that is far less true in many other places.
