Quick verdict

For many Caribbean trips, start watching fares before the 24 to 69 day window and take a strong price seriously once you are in it. For Christmas, New Year, and spring break, start earlier. The most useful tactic is still tracking the exact island and airport pair you want, because Caribbean routes do not all move the same way.

How to do this

Use 24 to 69 days as the main booking window: Google's current guidance for Mexico and Caribbean travel points to a lower-price window 24 to 69 days before departure, with about 43 days out as the clearest target. Once you are in that range, a solid fare is worth taking seriously.
Start earlier for Christmas, New Year, and spring break: Peak beach weeks tighten faster than ordinary travel dates. If the trip falls around a school break or holiday, start monitoring well before the general window and expect nonstop flights to move first.
Track the exact island and airport pair: Treat San Juan, Aruba, Nassau, Montego Bay, and St. Lucia as separate markets. The best time to buy can shift with airport size, airline competition, and how many seats serve that route.
Test the small flex points that change price fastest: Check a one-day shift in either direction, a nearby departure airport, and one-stop options. Caribbean leisure trips cluster around the same weekends, so small changes can reshape the fare.
Use Google Flights if you are actively shopping one route: Google Flights can track a searched route, flight, or date and notify you when the price changes. That works well when you are already planning one specific trip and do not mind setting up the search yourself.
Use a wishlist if you care about several islands over time: Snagfly is 29.99 USD per year (about 2.50 USD per month), billed annually only with a free 7-day trial, alerts only when a fare falls 50 to 90 percent below the verified rolling 90-day median for that route, caps emails at 3 per week and 1 per day, and sends you to book directly with the airline, with no markup. If you already know the Caribbean routes you want, pin them once and let Snagfly keep watching.

FAQ

How far in advance should I book Caribbean flights?

For many Caribbean trips, the best current window is 24 to 69 days before departure, with Google data pointing to about 43 days out as a useful target.

Does the same timing work for Christmas and New Year trips?

Christmas, New Year, and spring break usually need earlier tracking and earlier booking than the general Caribbean window because demand is higher and nonstop seats tighten sooner.

Are Caribbean flights ever cheaper at the last minute?

Last-minute Caribbean fares can drop on some softer routes, but popular islands and peak dates are more likely to get more expensive than cheaper.

Is Google Flights enough for Caribbean airfare alerts?

Google Flights is useful for tracking a route, flight, or date you already searched, but a wishlist service is better when you want ongoing alerts for the exact islands you care about without rebuilding searches.
