Planning Based on Transportation

Your arrival time should be primarily determined by how you plan to reach the terminal. If you are being dropped off curbside, 1.5 hours is typically sufficient to get through check-in and security. If you are driving yourself, you must factor in the time required to park your vehicle and potentially take a shuttle from the Economy Lot to the terminal building.

Navigating Peak Travel Hours

  • Morning Peak: 5:00 AM – 8:00 AM
  • Afternoon/Evening Peak: 4:00 PM – 7:00 PM

Efficiency Tips for BOI Travelers

While TSA PreCheck can significantly expedite the security screening process, it does not exempt travelers from the need to arrive on time. You should still arrive within the recommended 1.5 to 2-hour window to account for non-security variables like parking capacity, bag drop-off deadlines set by your airline, and terminal navigation.
