The other week Westjet announced it will offering flights to Trinidad from Canada during the winter season. For people who are look for air-only tickets this might be a good thing. I checked out out their website and was quoted a price less than $400 for a return flight out of Toronto. It appeared that taxes were included. If this is their regular price then it might be a great route to get to MI. It would depend on the cost of a return flight to MI from Trinidad and the frequency of those flights.
