Cheapest Months to Travel
September, October, and November tend to have the lowest fares. Hurricane season keeps demand down, though San Juan rarely gets direct hits. You'll find good deals if your dates are flexible.
Peak Travel Seasons to Avoid
December through April is when fares are highest. Holiday travel, winter escapes, and spring break all push prices up significantly on this route.
Best Time to Book
Book 3 to 6 weeks in advance for the best pricing. For holiday travel, 8 to 12 weeks ahead is safer to lock in a reasonable fare.
Midweek Advantage
Tuesdays and Wednesdays are typically cheaper for San Juan flights on Frontier. Weekend demand from both tourists and Puerto Rican diaspora keeps Friday and Sunday fares higher.
Time Difference to Keep in Mind
Puerto Rico runs on Atlantic Standard Time year-round (UTC-4). During winter, San Juan is 1 hour ahead of the US East Coast. During summer daylight saving, they're on the same time. The West Coast is 4 hours behind San Juan in winter, 3 hours in summer.
