I guess we could call this an Semi-Oil Run? From New York to Port of Spain, Trinidad via Miami with American Airlines. British Airways flyers would obtain 160TPs on this route. Most travelers would usually this a base to explore Tobago or other islands in the region, although Port of Spain has some interesting places to see.
Most flights are on normal US Domestic Flights with a 2-2 seating. Here is a Trip Report from EWR-DFW on an Airbus 321 from 2019.
