Frontier Airlines currently operates at Los Angeles International Airport (LAX) primarily out of Terminal 1 , with some flights using Tom Bradley International Terminal (Terminal B) west gates for departures.

  • Most check‑in, security, and all arrivals are handled at Terminal 1.
  • Some departures board from Terminal B (Tom Bradley), with passengers typically checking in and clearing security at Terminal 1, then taking an airside shuttle to the west gates.

Because LAX gate and terminal assignments can change, always double‑check your specific flight on:

  • Your booking confirmation or airline app, and
  • The live LAX “Flight Status” page on the day of travel.
