St. Louis Lambert International Airport is not a very big airport, and travellers report that it usually takes under 15 minutes to get through security and to your gate. During peak travel periods, such as early mornings and evenings, wait times tend to be longer, but even then, travellers report wait times of up to 10 minutes. If you are connecting flights, a layover of 45-55 minutes is considered to be enough time, as the terminals are relatively small and linear.

The St. Louis airport is small and can be traversed in 10 minutes
St. Louis Lambert International Airport (IATA: STL) is the primary international airport serving metropolitan St. Louis, Missouri, United States. Covering 3,793 acres of land, it is the largest and busiest airport in the state of Missouri. Despite its size, the airport can be traversed in 10 minutes, as attested to by several sources.
One source states that the Southwest Airlines concourse can be traversed in under 10 minutes, with the record being under 7 minutes. Another source mentions that the airport is "tiny" compared to others like Atlanta or Chicago. This is echoed by another commenter, who refers to the airport as a "baby airport".
The small size of the airport is advantageous for passengers with layovers, as they can easily reach their next gate within a short time. For example, one passenger with a 55-minute layover mentions that they had enough time to deplane, have a drink at a bar, walk down the concourse, and still have time to spare. Another passenger with a 45-minute layover on Southwest Airlines, which operates out of Terminal 2, mentions that it is "not an issue in the slightest" as the terminal is small and linear.
However, it is important to note that the time required for luggage transfer between connecting flights may vary. While the airport provides a lost and found section and baggage claim locations, some passengers have experienced delays in receiving their checked luggage. Therefore, while the St. Louis airport can be quickly navigated, the efficiency of luggage transfer should also be considered when assessing layover times.

A 55-minute layover is enough time to deplane, eat, and walk the concourse
St. Louis Lambert International Airport (STL) is the only major airport serving St. Louis and is located 12 miles from the city centre. It is used by airlines such as Southwest, American, United, Frontier, Delta, and Southern Airways Express.
A 55-minute layover at St. Louis Airport is enough time to deplane, eat, and walk the concourse. The airport is relatively small compared to others such as Atlanta or Chicago. One passenger even commented that they had a 20-minute layover in Dallas and were still able to make it from one end of the terminal to the other without running.
If you are travelling with Southwest, you will be in Terminal 2, which is very easy to navigate. Terminal 2 is also where you will find food options such as Shake Shack, Blue Note, and Auntie Anne's Pretzels. There is also a grab-and-go station outside a restaurant between gates 18 and 20, and another one at the big curve heading for gates 34+. However, it is important to be quick and efficient if you want to grab a bite to eat, and you may prefer to bring your own food to save time.
In addition to eating, you will have time to walk down the entire concourse and back to your gate. If your incoming and outgoing gates are close together, you may even have time to watch an episode of a TV show before boarding your next flight.

Peak hours at the airport are 5:00-8:00 and 4:00-7:00, with higher passenger volumes
Peak hours at St. Louis Lambert International Airport are 5:00 a.m.–8:00 a.m. and 4:00 p.m.–7:00 p.m. During these times, the airport experiences higher passenger volumes due to the number of departing and arriving flights. As a result, security lines tend to be longer, and wait times can be longer too.
If you're travelling during peak hours, it's recommended that you arrive at the airport early to account for the longer wait times. You can also speed up your security process by ensuring that you have the necessary documents readily available, such as your boarding pass and identification. Additionally, familiarizing yourself with TSA guidelines and procedures, as well as packing your liquids and gels according to regulations, can contribute to a smoother experience.
The average wait time at St. Louis Lambert Airport is reported to be up to ten minutes. However, during peak travel periods, these wait times can extend. Off-peak hours at the airport are generally late mornings to early afternoons and late evenings, specifically between 10:00 a.m. and 3:00 p.m., and after 8:00 p.m., when passenger traffic is lighter.
The size of the airport also plays a role in determining the required layover time. St. Louis Airport is considered relatively small, making it easier to navigate within a short time frame. Individuals with personal experience at the airport have reported that a 55-minute layover is sufficient to deplane, walk the concourse, and even purchase snacks or drinks.
However, it's important to consider factors such as the time required for the airline to unload and load checked baggage for your connecting flight. While St. Louis Airport may be small, baggage claim processes can sometimes be lengthy. Therefore, when determining the ideal layover duration, it's crucial to take into account both the size of the airport and the potential time needed for baggage handling.

The longest part of the airport day is when your gate is at the end of the terminal
St. Louis Airport is not very big, and travellers with a layover can easily traverse the concourse in under 10 minutes. However, the longest part of the airport day is when your gate is at the end of the terminal, and you have to walk with your luggage. This can be a tiring and time-consuming process, especially if you have mobility limitations or heavy luggage.
When your gate is at the end of the terminal, you might have to walk a considerable distance, which can be challenging, especially if you are running late or have a tight connection. The walk can be even more daunting if you are travelling with children, have mobility issues, or are carrying multiple bags. In such cases, you can contact the information booth upon arrival and request an escort to be dispatched to your location.
Additionally, the time taken to walk to your gate can be further extended if you need to stop for food or use the restroom. The food lines at St. Louis Airport can be long, and the quality of the food has been described as terrible. Therefore, it is advisable to grab snacks from a convenience store like Hudson News or use one of the vending machines.
Furthermore, if you have checked baggage, you may need to factor in additional time for your luggage to be unloaded and loaded onto your connecting flight. Baggage claim and retrieval can sometimes take over an hour, and there is a risk of your luggage being misplaced or sent on a different flight. Tracking your bags through the airline's app can help alleviate some of the stress and keep you informed about their location.
Overall, while St. Louis Airport is relatively small, the time taken to reach your gate, especially if it is at the end of the terminal, can feel like the longest part of your airport experience, impacting your overall journey and potentially causing delays if you have a tight connection.
