Yes, Boston Logan International Airport (BOS) is exceptionally busy, currently ranking as the 16th busiest airport in the United States as of early 2026. Handling over 43 million passengers annually, it serves as a primary transatlantic gateway and a major hub for JetBlue and Delta. In 2026, traffic has reached record levels, surpassing pre-pandemic benchmarks and often leading to significant congestion in the central parking areas and at Terminal E security during evening international rushes. A high-value peer tip for 2026: Logan is notorious for its "tunnel traffic" and limited roadway access; always allow an extra 45 minutes for travel to the airport if you are using a ride-share or taxi during peak commuting hours. Despite its size, Logan is praised for its efficient "Silver Line" bus connection and the integrated AirPower system that makes moving between its five terminals relatively straightforward for the millions of travelers passing through each month.
