After check-in, proceed to the TSA security checkpoint in Terminal A. Security wait times can vary depending on the time of day and season, so arriving at least 2 hours before your scheduled departure is recommended.

Once you clear security, board the automated people mover (tram) to reach Airside 1. The ride takes less than 2 minutes and delivers you directly to Frontier’s departure gates. Digital signage and staff are available along the way to guide you.

What to Expect at the Gate Area
Frontier Airlines uses a zone boarding system, clearly marked on boarding passes. Boarding announcements begin approximately 30 to 40 minutes before flight departure. Be sure to arrive early at the gate to avoid missing your boarding window.

Airside 1 offers a functional and passenger-friendly experience. It includes:

Flight information displays

Comfortable seating

Charging stations (though they can be limited)

Family restrooms and ADA-compliant facilities

While Airside 1 isn’t as expansive as some international terminals, it has all the essentials for a short domestic flight wait.
