Cheap Flights from San Juan to Philadelphia — $82

Luis Muñoz Marín International Airport (SJU) serves as Puerto Rico’s primary international gateway and usually functions as the island’s main hub for both legacy carriers and several low-cost airlines. Located about 10 miles (16 km) from Old San Juan, travel into the city center commonly takes 15–30 minutes by taxi or rideshare and roughly 45–60 minutes by public bus; fares commonly range from inexpensive bus tickets to moderate taxi/ride-share costs. The airport typically offers a mix of international connections, regional flights, and domestic U.S. service. Pros include frequent flight options and relatively short transfer times; possible downsides are occasional congestion at peak times and longer waits for ground transport during major events.

Philadelphia International (PHL) acts as the region’s main international and domestic hub, serving legacy carriers like American Airlines alongside a mix of low-cost and regional operators. Flights here can be competitively priced compared with larger East Coast gateways, though fares vary by season. The airport sits about 8 miles southwest of downtown Philadelphia; the SEPTA Airport Line typically takes around 25–30 minutes to 30th Street Station with fares usually under $10, while taxis or rideshares are often 20–30 minutes depending on traffic and can cost more. PHL offers broad connectivity and full services, but busy terminals and security lines can make peak times less relaxed for quick transfers.
