Pro Tips for Finding Cheap Flights to San Juan

Fly During Off-Peak Seasons: Snag cheaper flights to San Juan by traveling during the off-season, like late spring or early fall. You'll dodge the tourist crowds and inflated prices – win-win!
Be Flexible with Your Dates: Got a little wiggle room in your schedule? Play around with different travel dates! Mid-week flights (Tuesday and Wednesday) are often lighter on your wallet than weekend getaways.
Set Up Price Alerts on RatePunk: Don't have time to constantly check flight prices? No sweat! Set up a price alert on RatePunk and let the app do the work. You'll be the first to know when prices drop, ensuring you catch the best deal!
Consider Nearby Airports: Sometimes, flying into a smaller, less popular airport near San Juan can save you some serious cash. Check out airports like Rafael Hernández Airport in Aguadilla – you might be surprised!
Mix and Match Airlines: Don't be afraid to mix and match airlines for your outbound and return flights. Sometimes booking with different carriers can unlock significant savings.
Book in Advance (But Not Too Early!): While last-minute deals are rare, booking too far in advance isn't always the best strategy either. Aim to book about 2-3 months before your trip for the sweet spot in pricing.
Embrace Red-Eye Flights: If you can handle a little sleep deprivation, red-eye flights (those overnight journeys) often come with a lower price tag. Just think of it as extra time to explore San Juan once you land!
Look for Package Deals: Keep an eye out for package deals that bundle flights and accommodations. These can sometimes be cheaper than booking everything separately, especially if you find a good deal with a trusted vendor.
Use Incognito Mode: Airlines and travel sites sometimes track your browsing history and raise prices based on your interest. Browse in incognito mode to see the most unbiased prices.
Leverage Travel Rewards: If you're a travel rewards member, now's the time to cash in those points or miles! You might be able to snag a nearly-free flight to San Juan, leaving you with more spending money for delicious mofongo.
By keeping these tips in mind, you’ll be well-equipped to find the cheapest flights to San Juan and make the most of your travel budget. After all, the more you save on your flight, the more you can spend on a Broadway show, a nice meal, or an extra tour in San Juan! 🎉✈️
