Clearing customs and immigration at Boston Logan International Airport (BOS) typically takes between 30 and 60 minutes, though this can fluctuate wildly based on the arrival of multiple "heavy" international flights in Terminal E. During peak afternoon windows (2:00 PM – 5:00 PM), wait times can occasionally exceed 90 minutes. In 2026, travelers using Global Entry or the Mobile Passport Control (MPC) app often breeze through in under 10 minutes, as these programs have dedicated lanes that bypass the primary kiosks. Once you pass through passport control, you must collect your bags and walk through the "Customs" exit; if you have nothing to declare, this part is almost instantaneous. For domestic travelers, there is no customs check. To ensure a smooth arrival, Logan officials recommend allowing at least three hours if you have a connecting flight, as you must re-clear TSA security after entering the United States.
