On average, it takes about 12 to 20 minutes to get through security at Boston Logan International Airport (BOS), though this varies significantly by terminal and time of day. During peak morning hours (5:00 AM – 8:00 AM) and evening rushes (4:00 PM – 7:00 PM), wait times can spike to 25–30 minutes. Terminal B and Terminal C tend to be the busiest due to the high volume of domestic flights from JetBlue, American, and United. If you have TSA PreCheck, your wait is typically under 5 minutes, and many terminals at Logan now also offer CLEAR for even faster processing. To ensure a smooth experience, the airport authority (Massport) recommends arriving 2 hours prior to domestic departures and 3 hours prior to international departures, especially since Terminal E (International) can have longer queues during the evening departure bank for European flights.
