We do not offer or include airfare in our rates. With so many competitive air travel sites on the web, a diligent search often yields surprisingly good results. We use several different sites for this ourselves such as Travelocity, Expedia, Kayak, and Cheaptickets.com, to name a few.
The major airlines that fly to Jamaica such as Delta, American Airlines, Jetblue, Air Canada and so forth also have their own websites. Be sure to check out Southwest Airlines’ website. Their offerings do not appear to show up in searches on the major travel sites. See if they serve an airport near you because they usually offer fantastic fares to Montego Bay and generous free baggage allowances.
