If you're flying with Frontier, it's essential to arrive at this specific terminal to ensure a smooth check-in and boarding process. The airport's layout is relatively straightforward, with clear signage directing passengers to the correct terminal. However, it's always a good idea to double-check your terminal information before heading to the airport, as gate assignments can occasionally change.

Lambert Airport Terminal Map
Navigating Lambert-St. Louis International Airport (STL) can be straightforward if you know where to look. The airport’s terminal map is a critical tool for passengers, especially those flying with Frontier Airlines. Frontier operates out of Terminal 1, which is the main terminal at STL. This terminal is divided into two concourses: Concourse A and Concourse C. Frontier Airlines typically uses Concourse C for its departures and arrivals, though gate assignments can vary. Understanding this layout ensures you arrive at the correct gate without unnecessary stress.
To effectively use the Lambert Airport terminal map, start by identifying Terminal 1. The map clearly marks the location of Concourse C, where Frontier Airlines gates are situated. Look for the blue or green lines on the map, which often denote different concourses. Concourse C is on the east side of Terminal 1, accessible via the main security checkpoint. If you’re checking in, Frontier’s ticket counters are located in the main hall, directly opposite the baggage claim area. Pro tip: Arrive at least 90 minutes before your flight to account for check-in and security lines, especially during peak travel times.
One common mistake travelers make is confusing Terminal 1 with Terminal 2, which is much smaller and primarily serves private flights. Always double-check your boarding pass or airline confirmation to confirm you’re heading to the right terminal. The terminal map also highlights key amenities near Concourse C, such as restrooms, charging stations, and dining options. For example, if you have time to spare, grab a quick bite at one of the food courts located near Gate C2. Knowing these details can make your travel experience smoother and more enjoyable.
For families or passengers with mobility concerns, the terminal map includes accessibility features like elevators, escalators, and wheelchair assistance points. Frontier Airlines offers pre-boarding for passengers needing extra time or assistance, so familiarize yourself with the nearest assistance desk, typically located near the security checkpoint. Additionally, the map shows the location of family restrooms and nursing rooms, which are often near high-traffic areas like Concourse C’s central corridor. Planning ahead with these specifics can alleviate travel-day anxiety.
Finally, leverage digital tools to complement the physical terminal map. Most airports, including Lambert, offer a mobile-friendly version of their map on their website or app. Downloading this ahead of time allows you to zoom in on specific areas, like Frontier’s gates in Concourse C, and even provides real-time updates on gate changes or delays.

The check-in process at Lambert is tailored to ensure efficiency, whether you’re a seasoned traveler or a first-timer. Here’s what you need to know to navigate it seamlessly.
Steps to Check-In: Begin by arriving at least 2 hours before your domestic flight or 3 hours for international travel.
