Boston is served mainly by Logan International Airport (BOS), the region’s primary international and domestic gateway, and by smaller general aviation fields nearby. Logan typically handles full-service carriers and major international airlines, while budget carriers also operate several routes; fares can be competitive but often rise during peak travel. The airport sits just across Boston Harbor, about 3–5 miles from downtown; travel options include the MBTA Silver Line bus (25–35 minutes, low single-digit fares), Blue Line + shuttle (20–30 minutes), taxis or rideshares (15–25 minutes, fares varying with traffic), and express shuttles. Pros: strong connectivity and frequent flights; cons: congestion, occasional delays, and airport fees that can add to ticket cost.
Lisbon Airport (Humberto Delgado, LIS) is Portugal’s main international gateway and typically functions as the city’s premium hub, handling long-haul carriers alongside a strong presence of European network and low-cost airlines. Located about 7–8 km northeast of central Lisbon, it can be reached by metro in around 20–30 minutes (single tickets usually fall in a low fare band) or by taxi and ride-hailing services in roughly 15–25 minutes depending on traffic, with airport express buses and local buses offering cheaper alternatives. Travelers can expect a mix of modern facilities and busy peak periods; conveniences include multiple lounges and good public transport links, while drawbacks can be crowding at peak times and occasional queues at security and passport control.
