SJC tips first-timers miss

  • Check your terminal: American, Delta, Frontier and United use Terminal A; Southwest, Alaska and Hawaiian use Terminal B
  • Both checkpoints reach every gate, since Terminals A and B connect after security
  • Checkpoints open at 4:00 a.m. (Terminal A) and 4:15 a.m. (Terminal B), so arriving earlier for a first-wave flight means waiting
  • PreCheck lanes are not open all day; they run during TSA-set peak periods
  • Reserve parking online to lock in a space; Economy Lot 1 is cheapest and has a 24-hour shuttle
