Use fare alerts to monitor any temporary promotions outside festival periods.

The best time to find cheap economy flights from Luis Muñoz Marín International Airport (SJU) is during shoulder seasons (April–May, September–October) and on weekdays (Tuesday–Thursday).

Direct flights from Luis Muñoz Marín International Airport (SJU) save time and reduce connection risk but can cost more in economy compared to connecting itineraries.
