Hi there! You’ll be going to Terminal 5 if you’re flying with Frontier Airlines out of LAX. Although it’s simple, it accomplishes the goal. Allow additional time because security queues might be hit or miss. While the Frontier Airlines LAX Terminal has a few good dining options, there may not be as much seating available during busy times. Expect to pay for refreshments and luggage as part of the trade-offs associated with Frontier’s low rates. In general, if you know what to anticipate, it’s okay. Have a safe trip!
