Massport works with the TSA to monitor security line length and tries to keep the wait time less than 15 minutes; however to avoid any problems, we recommend arriving two (2) hours prior to domestic departures and three (3) hours prior to international departures to ensure adequate time for check-in, security screening ...

That depends on several factors, but here’s a general guide for Boston Logan International Airport (BOS):

For Domestic Flights

• Recommended arrival: 1.5 to 2 hours before your scheduled departure.
• Why: This allows time for check-in, bag drop (if needed), and security. Security wait times can vary significantly by terminal and time of day.

For International Flights

• Recommended arrival: At least 3 hours before your scheduled departure.
• Why: International flights often require additional document checks, and airlines have earlier cutoff times for check-in and baggage.

Key Factors to Consider (Adjust your timing based on these):

1. Time of Day & Day of Week:

   • Peak Times: Mornings (5:00 AM - 10:00 AM), holiday periods, and Monday mornings/Thursday evenings are busiest. Add extra time.
   • Evenings: Security lines are often shorter after 8:00 PM.

2. Traveler Type:

   • TSA PreCheck / CLEAR: You can often arrive closer to the 1-hour mark for domestic, as security lines are much faster.
   • Checking Bags: Airlines have strict cut-off times (usually 45-60 mins before departure for domestic). Factor in potential lines at the bag drop.
   • No Bags & Mobile Boarding Pass: You can proceed directly to security, saving significant time.

3. Terminal Knowledge:

   • Terminals A, B, C, and E are connected post-security, but
