After check-in, you’ll proceed to the security checkpoint. The PHL Frontier Terminal security area tends to be less congested than larger main-terminal checkpoints, making the screening process relatively swift. Remember to have your boarding pass and government-issued ID ready. Frontier passengers are permitted one personal item and one carry-on, but size restrictions are strictly enforced, so pack accordingly to avoid delays or additional fees.
