Frontier Airlines encourages passengers to check in online or through their mobile app to speed up the airport experience. If you’re bringing luggage, be sure to print your baggage tags at the self-service kiosks and drop them at the designated baggage counter. It's important to note that Frontier charges separately for carry-ons and checked bags, so pre-purchasing these services online can help avoid higher airport fees.

Security at Terminal 5 is managed by TSA, and like most terminals at LAX, the lines can get long, especially during peak hours. TSA PreCheck is available for eligible passengers, so if you qualify, this can significantly reduce wait times. Be sure to arrive at least two hours before your domestic flight to ensure a smooth process through check-in and security.
