What time does Boston Logan airport open in the morning?

The Boston Logan Airport is open 24 hours a day, however the TSA checkpoints vary in hours. The checkpoints for Terminals A, B, and C open at 4:00 AM and Terminal E checkpoints open at 4:30 AM.



Boston Logan International Airport (BOS) is technically a 24-hour facility, but its functional "opening" for passengers begins at 4:00 AM. Most airline check-in counters and TSA security checkpoints in Terminals A, B, C, and E begin operations between 4:00 AM and 4:30 AM to accommodate the first wave of "early bird" domestic departures, which typically start around 5:30 AM. If you are arriving on an international "red-eye," the Customs and Border Protection (CBP) area in Terminal E is staffed around the clock. However, don't expect much to be open before 5:00 AM; while the terminal itself is accessible, most Starbucks, Dunkin' locations, and newsstands don't open until 5:00 or 5:30 AM. If you have an exceptionally early flight, the "pro-tip" for 2026 is to arrive by 4:15 AM to beat the massive rush that usually hits around 5:00 AM, especially at the busy Terminal C (JetBlue) and Terminal B (American/United) checkpoints.
