Baltimore/Washington Thurgood Marshall Airport (BWI) functions as a major U.S. hub for both legacy and low-cost carriers, often serving as a more budget-friendly alternative to nearby Washington-area airports. Typical airlines include Southwest, American, Delta and several ultra-low-cost operators, so fares can be competitive, especially on domestic routes. BWI is about 10–12 miles south of downtown Baltimore; the light rail and shuttle buses connect the terminal to the city in roughly 25–40 minutes with fares often under $5–$15, while taxis and rideshares usually take 20–30 minutes depending on traffic and cost more. Pros: good low-cost connectivity and modern facilities; cons: can feel busy during peak periods and is farther from some central neighborhoods than smaller city airports.

Luis Muñoz Marín International Airport (SJU) is Puerto Rico’s primary international gateway, typically serving a mix of full-service carriers and regional airlines on transcontinental and Caribbean routes. Flights here can be mid-to-higher in price compared with smaller island airports, though low-cost carriers may offer budget options. The airport sits about 10–20 minutes (7–10 km) from Old San Juan by car; taxis and ride-hailing usually take 15–25 minutes, while shared shuttles and buses can take 25–45 minutes depending on stops, with fares varying by service. Pros: comprehensive amenities, many nonstop options and good ground-transport links. Cons: can be busy during peak seasons and may involve longer queues and higher parking or on-site costs. Isla Grande Airport (SIG) is a smaller, domestic-focused facility close to central San Juan that typically caters to general aviation, regional commuter flights and some charter services rather than major international carriers. Because it’s nearer to the city — generally a 5–15 minute drive to Old San Juan — it can be a convenient, lower-hassle alternative for short hops; however, options and scheduled frequencies are more limited than at the international airport. Ground transport is mostly taxis, ride-shares and private transfers with short travel times; public bus links are less frequent. Pros: quick access and simpler terminals. Cons: fewer commercial flight choices and limited amenities.

Fly nonstop from San Juan to Baltimore for the quickest, most convenient way to get between Puerto Rico and the Mid-Atlantic — less hassle, no layovers, and more time to enjoy your trip.
