Which airlines is good to travel around the caribbean directly?

I am going for my senior trip to the Caribbean and we will be needing to travel to several countries in our trip and not waste so much money, with that said can anyone help, ohh and the countries will most likely be, Jamaica, St. martin, bahamas, B.V.I., barbados. Thanks. (If there is a cheaper way to travel by boat plese do tell)

The only airlines that offer great connections throughout the Caribbean are:

* American Airlines/American Eagle (from San Juan): Provides service to every major island in the region with the exception of Cuba, Haiti, Jamaica, Turks & Caicos, the Bahamas and the Cayman Islands.

*LIAT (from Antigua): Reliable service to most of the Lesser Antilles and Puerto Rico.

*Air Jamaica (from Kingston and Montego Bay): Service to Cuba, the Cayman Islands, the Bahamas, Grenada, Curacao and St. Lucia.
