Booking
Spirit Airlines runs nonstop flights to San Juan, Puerto Rico from several US cities. The best part: since Puerto Rico is a US territory, you don't need a passport and there's no customs line. Fares are often surprisingly low, especially during the fall months. Mundo Trip can help you compare dates and lock in the best price.
Cheapest Months to Travel
September, October, early November tend to offer the lowest fares on Spirit flights to San Juan. Demand drops during these months, and you'll find better pricing and availability.
Peak Travel Seasons to Avoid
December through April is peak season for Puerto Rico. Holiday weeks and spring break push fares up significantly.
Best Time to Book
For Spirit flights to San Juan, booking 4 to 8 weeks ahead usually gets you the best prices. For holiday or peak travel, booking 2 to 3 months in advance is safer.
Midweek Advantage
Tuesday and Wednesday departures on Spirit are almost always cheaper than Friday or Sunday flights. If you have flexible travel dates, shifting by a day or two can make a real difference.
Time Difference to Plan For
San Juan is in the Atlantic Time Zone (AST), which is 1 hour ahead of New York (ET) and does not observe Daylight Saving Time. During US Daylight Saving Time, San Juan and New York are in the same time. Planning around the time difference helps you pick better connection times and arrival windows.
