The Caribbean has a deal for every budget if you pick the right island and time it well. Here are the cheapest gateways from the US and exactly when to book them.
The cheapest islands to fly to
| Island | Passport? | Why it's cheap |
|---|---|---|
| Puerto Rico (SJU) | No (US territory) | Heavy competition, no passport friction - often the cheapest |
| Dominican Republic (PUJ/SDQ) | Yes | 2026 breakout; dense flights keep fares low |
| Jamaica (MBJ/KIN) | Yes | Strong resort competition, frequent deals |
| Aruba (AUA) | Yes | Good value, dry climate (outside hurricane belt) |
| Curaçao (CUR) | Yes | Rising deal availability, fewer crowds |
Puerto Rico is the easy winner for spontaneous trips - no passport, US dollars, and consistently competitive fares. The Dominican Republic is the breakout of 2026 with plenty of deals despite surging demand. All five appear in our broader cheapest places to fly in 2026 guide.
The cheapest time to fly to the Caribbean
Low and shoulder season - roughly late spring through fall - has the lowest fares. This overlaps hurricane season (June-November), which is why prices dip; the risk is real but manageable with flexible plans and travel protection. The most expensive window is mid-December through March, peak winter-sun season, plus spring break. Aruba and Curaçao sit outside the main hurricane belt, making them safer shoulder-season bets.
