JetBlue continued its 12 days of deals on Saturday, with flights to Puerto Rico and the Dominican Republic starting at $20. Availability is limited, so this is a now or never booking situation.

The cheapest flights, for $20 to $25, are between Caribbean destinations like San Juan and Saint Thomas. Flights from Florida to San Juan are available for $50. Flights from New York City to the Dominican Republic are available for $100.

The sale is Saturday only, so flights must be booked before 11:59 p.m. ET.

JetBlue is revealing a new deal each day at 1 p.m. ET through next week. If you haven't booked a winter getaway yet, set an alarm. Previous days' deals have included $54 flights to Cuba, and more $20 flights.
