How this was worked out

Standard domestic guidancePublished guidance · US airlines and the TSA commonly recommend arriving two hours before a domestic departure.+120 min
Peak departure hourFlyerIntel data · Your departure hour is among the busiest at OAK, so check-in, bag drop and security all queue at once.+20 min
What this does not include.
  • FlyerIntel cannot currently obtain live security wait times for OAK, 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.
