What this does not include.
  • FlyerIntel cannot currently obtain live security wait times for BOS, so this figure does not account for the queue on the day.
  • It does not include your journey to the airport, parking, or a shuttle from a remote lot.
  • International departures, and travel with children, checked pets or special assistance, need more time.
