Located mostly in East Boston and partially in Winthrop, Massachusetts, Boston Logan International Airport covers 2,384 acres and features six runways. As the largest airport in Massachusetts and New England, it processed 43.5 million passengers in 2024. Logan serves as a northeastern hub for Cape Air, a secondary transatlantic hub for Delta Air Lines, an operating base for JetBlue, and a major focal point for American and United.
The airport is organized into four lettered passenger terminals: A, B, C, and E. Inbound international flights arrive at Terminal E for customs screening, except those with U.S. border preclearance. All terminals are linked pre-security by moving walkways, shuttle buses, and MBTA Silver Line BRT service, while indoor post-security walkways connect Terminals B, C, and E for seamless passenger transfers.

Lost, delayed or damaged baggage at BOS
If your checked bag doesn't turn up on the belt, act before you leave the baggage-claim area — that's where every airline keeps its Baggage Service Office.
- Go to your airline's Baggage Service Office in the baggage-claim hall of your arrival terminal.
- File a Property Irregularity Report (PIR) and get your file reference (WorldTracer) number. Keep your bag-tag receipt and boarding pass.
- Track it online using that reference on your airline's baggage-tracking page — most bags are located within 24–48 hours.
- Claim your essentials. On delayed bags airlines reimburse reasonable interim purchases (toiletries, clothing) — keep receipts. International trips are covered by the Montreal Convention.
- If it's truly lost (generally after 21 days) or damaged, file the claim at the same office — damage must be reported before you leave the airport.
Left something in the terminal (not a checked bag)? That's handled by the airport Lost & Found. Items left at a TSA security checkpoint are held by the TSA, not the airline.
