There are a limited number of flights per week between Northern America and Suriname. From Toronto, New York and Miami, you might book on Carribean Airlines, but there are only three flights per week via Post-of-Spain (Trinidad). An interesting option though costly in CO2 (2500 Kg) and more expensive (but regular) is to fly to Amsterdam and commute to Paramaribo the same day. See Northwest/KLM
