Travelers at St. Louis Lambert International Airport are facing long lines and missed flights as congestion peaks in July 2025. With new REAL ID rules and busy summer travel, passengers must plan carefully to avoid delays and frustration.
St. Louis Lambert International Airport (STL) is experiencing one of its busiest periods in recent memory. On July 13, 2025, travelers reported long security lines, missed flights, and mounting frustration. According to an airport spokesman, this surge is partly due to the summer travel rush, which brings thousands of passengers through STL’s terminals each day. The situation highlights the growing challenges faced by both travelers and airport staff as they try to keep up with rising demand and new federal identification requirements.
Why Are Lines So Long at St. Louis Lambert International Airport?
Several factors are causing the current congestion at STL. First, the summer months always see a spike in travel, with families, students, and business travelers all taking to the skies. This year, the numbers are even higher, as more people feel comfortable traveling again. Second, new security rules, including the REAL ID requirement, are slowing down the process at checkpoints.
REAL ID is a federal law that sets higher security standards for state-issued driver’s licenses and identification cards. Starting May 7, 2025, all travelers aged 18 and older must show a REAL ID-compliant license or another form of identification accepted by the Transportation Security Administration (TSA) to pass through security at STL and all other U.S. airports. Many travelers are still adjusting to this change, and some arrive at the airport without the correct ID, causing further delays.
How Security Checkpoints Work at STL
St. Louis Lambert International Airport has three main security checkpoints. Each checkpoint offers TSA PreCheck lanes, which allow approved travelers to move through security faster. TSA PreCheck is a program that lets travelers keep their shoes, belts, and light jackets on, and leave laptops and liquids in their bags. This speeds up the process and helps reduce lines for everyone.
Despite these efforts, the average security wait time at STL is about 28 minutes and 48 seconds. This is longer than many other U.S. airports, especially during peak hours. Some travelers have reported waiting even longer, especially during early morning and late afternoon rushes.
To help manage the crowds, STL also offers CLEAR+, a private service that uses biometric technology (like fingerprints or eye scans) to verify a traveler’s identity. CLEAR+ members can skip the regular ID check and go straight to the physical screening. At STL, CLEAR+ is available at Terminals 1-A, 1-C, and 2-E.
What Travelers Are Saying
Many passengers have voiced their concerns about the long lines and missed flights. Some say they arrived at the airport two hours before their flight, only to find themselves still in line as their boarding time passed. Others have missed important connections or had to rebook flights, leading to extra costs and stress.
A frequent flyer from St. Louis shared, “I’ve never seen lines this long at STL. Even with TSA PreCheck, it took me almost 40 minutes to get through security. People were frustrated, and some were crying because they missed their flights.”
Airport staff are working hard to keep things moving, but they admit that the surge in travelers and new ID checks are making their jobs more difficult. “We’re doing our best, but we ask passengers to arrive early and be patient,” said a TSA officer at STL.
The Impact of REAL ID on STL Travelers
The REAL ID law is one of the biggest changes affecting air travel in the United States 🇺🇸 this year. The law was passed after the September 11 attacks to make it harder for people to use fake IDs to board planes. Now, all states must issue driver’s licenses and ID cards that meet strict federal standards.
At STL, travelers who do not have a REAL ID-compliant license must show another form of approved identification, such as a passport or a military ID. If they do not have the right ID, they will not be allowed to pass through security, even if they have a valid ticket.
Key points about REAL ID at STL:
– Effective Date: May 7, 2025
– Who Needs It: All travelers aged 18 and older
– What to Bring: REAL ID-compliant license or another TSA-accepted ID
– What Happens Without It: You cannot pass through security or board your flight

How to Check Security Wait Times
To help travelers plan ahead, STL and the TSA offer several tools to check real-time security wait times. The TSA’s My TSA app provides up-to-date information on wait times at all three STL checkpoints. The airport’s own website also posts current wait times and tips for getting through security faster.
Tips for managing wait times:
– Check wait times before leaving home using the TSA app or STL’s website
– Arrive at least two hours before your flight for domestic travel, and three hours for international flights
– Consider enrolling in TSA PreCheck or CLEAR+ for faster screening
– Have your REAL ID or other approved ID ready before you reach the checkpoint
TSA PreCheck and CLEAR+: What’s the Difference?
Both TSA PreCheck and CLEAR+ help travelers get through security faster, but they work in different ways.
TSA PreCheck:
– A government program that requires a background check and fingerprinting
– Approved travelers get a Known Traveler Number (KTN) and can use special lanes at security
– Lets you keep shoes, belts, and light jackets on, and leave laptops and liquids in your bag
– Available at all STL checkpoints
CLEAR+:
– A private service that uses your fingerprints or eyes to confirm your identity
– Lets you skip the regular ID check and go straight to the screening area
– Requires a separate membership and fee
– Available at Terminals 1-A, 1-C, and 2-E at STL
Some travelers use both programs together for the fastest possible experience. For example, a CLEAR+ member with TSA PreCheck can use CLEAR+ to skip the ID check, then go through the PreCheck lane for a quicker screening.
Flight Delays and Missed Connections
Long security lines are not the only problem at STL this summer. The airport also sees an average of 12.1 minutes of flight delays during the summer months. While this is not as bad as some larger airports, it can still cause problems for travelers with tight connections or important meetings.
Tarmac wait times at STL are generally shorter than at bigger airports, but the overall efficiency of the airport depends on how well it handles the flow of passengers through security and onto their flights. When lines get too long, even a small delay can snowball into missed flights and unhappy travelers.
What Can STL Do to Improve the Situation?
As travel demand continues to rise, experts say that airports like STL will need to take more steps to manage congestion and improve the passenger experience. Some possible solutions include:
– Expanding security checkpoints to handle more passengers at once
– Adding more TSA staff during peak hours
– Upgrading technology to speed up ID checks and screening
– Encouraging more travelers to enroll in TSA PreCheck or CLEAR+
– Providing better real-time information about wait times and delays
According to analysis by VisaVerge.com, smaller airports like STL usually benefit from having fewer long-haul flights and less overall traffic compared to major hubs. However, during busy times, even these airports can struggle to keep up with demand.
Advice for Travelers: How to Avoid Problems at STL
If you are flying out of St. Louis Lambert International Airport this summer, here are some steps you can take to make your trip smoother:
1. Arrive Early: Give yourself plenty of time to get through security, especially if you are traveling during peak hours (early morning, late afternoon, or holidays).
2. Check Your ID: Make sure you have a REAL ID-compliant license or another approved form of identification before you leave home. If you are not sure, check the TSA REAL ID page.
3. Use Technology: Download the TSA’s My TSA app or visit the STL website to check current wait times and get tips for faster screening.
4. Consider TSA PreCheck or CLEAR+: If you travel often, enrolling in one or both programs can save you time and stress at the airport.
5. Pack Smart: Follow TSA rules for liquids, electronics, and other items to avoid extra screening or delays.
6. Stay Informed: Keep an eye on your flight status and be ready for possible delays. Sign up for text alerts from your airline if available.
The Broader Impact on the Community
The congestion at STL affects more than just travelers. Airport staff, airline workers, and local businesses all feel the impact when flights are delayed or passengers miss connections. For families, students, and business travelers, a missed flight can mean lost time, extra costs, and added stress.
Local hotels and transportation services may also see changes in demand as travelers adjust their plans. Some may choose to arrive in St. Louis a day early or stay overnight if they miss a flight. This can help local businesses, but it also puts pressure on the city’s infrastructure.
What Are Officials Doing?
Airport leaders and city officials are aware of the problems and are working to find solutions. The St. Louis Airport Commission holds regular meetings to discuss policy changes, new technology, and ways to improve the passenger experience. Travelers can find updates and meeting schedules on the City of St. Louis Airport Department website.
The TSA is also working to hire more staff and improve training to handle the summer rush. They encourage travelers to use TSA PreCheck and CLEAR+ to help reduce lines for everyone.
Looking Ahead: The Future of STL
As more people return to air travel, STL and other airports across the United States 🇺🇸 will need to keep adapting. This could mean bigger security areas, more staff, and better technology to keep lines moving. It may also mean more communication with travelers about what to expect and how to prepare.
For now, the best advice is to plan ahead, arrive early, and be patient. The airport experience can be stressful, but with the right preparation, travelers can avoid the worst delays and enjoy a smoother journey.
