Boston Logan International (BOS) serves as the region’s primary international gateway and a full-service hub for major carriers, while smaller general aviation fields sit on the city’s periphery. Logan typically hosts a mix of legacy airlines and several low-cost carriers, so fares can range from premium on transatlantic routes to competitively priced domestic options. The airport lies roughly 3–5 miles from downtown Boston; taxis and rideshares usually take 15–30 minutes depending on traffic, shuttle services and the MBTA Silver Line bus provide 20–35 minute links (fares often under a few dollars), and the Blue Line plus free shuttle connects to terminals. Pros: central location and frequent flights; cons: can be busy with variable traffic delays and parking costs.
Luis Muñoz Marín International Airport (SJU) is Puerto Rico’s primary international gateway and a full-service hub for both legacy and low-cost carriers, typically handling most transatlantic, mainland U.S., and regional flights. It sits about 8 miles (13 km) east of Old San Juan, with taxi rides to the city center usually taking 15–25 minutes and costing roughly in the mid-single to low double digits; public buses and airport shuttles offer cheaper alternatives but can be slower. SJU tends to be competitively priced compared with smaller regional airports, especially on nonstop routes. Pros: broad route network and multiple ground-transport options; cons: periods of heavy traffic and occasional queueing at peak times.
