Frequently Asked Questions
What are the TSA checkpoint hours at Boston Logan?
Security checkpoints at BOS typically open approximately 2 hours before the first departure of the day. There is no published closing time — hours vary by flight schedule. TSA PreCheck lanes are available at all four terminals.
Does BOS have TSA PreCheck?
Yes — TSA PreCheck is available at all four terminals (A, B, C, and E) at Boston Logan. Dedicated PreCheck lanes are available from approximately 4:30am until late evening.
Are the BOS terminals connected after security?
Terminals B, C, and E are connected post-security via airside walkways — you can walk between them without re-clearing security. Terminal A (Delta only) is isolated and is not connected airside to any other terminal.
How long are BOS security lines?
Boston Logan security wait times typically range from 15–30 minutes. Peak hours are 6–9 AM and 4–7 PM. Midday flights (11 AM–2 PM) usually have the shortest lines. TSA PreCheck and CLEAR reduce wait times significantly.
Which BOS terminal should I use for my airline?

Terminal C serves JetBlue, Aer Lingus, Cape Air, Etihad, and TAP Air Portugal. Terminal E handles international flights including British Airways, Lufthansa, Air France, and Emirates.

How early should I arrive at Boston Logan?
Arrive at least 2 hours before domestic flights and 3 hours before international departures. The free MBTA Silver Line SL1 runs from all terminals to South Station in downtown Boston — a reliable option to avoid traffic.
How do I get between terminals at BOS?
Pre-security, a free inter-terminal shuttle bus and the MBTA Silver Line SL1 connect all terminals. Post-security, Terminals B, C, and E are connected via airside walkways. Terminal A passengers must exit security and take the shuttle to reach other terminals.
