What to Consider for On-Time Arrival at St Louis Lambert Airport

Preparing your Documents

Make sure you prepare all your necessary documents before heading to St. Louis Lambert Airport to ensure a smooth travel experience. Typical required documents include:

Identification: For domestic flights within the U.S., acceptable forms of identification include state-issued driver's licenses or ID cards, among others listed on the TSA website. If your ID has expired, check that it expired within the last year to remain valid.

Visa: If you're flying internationally from STL, verify the visa requirements for your destination well in advance to avoid any last-minute complications upon arrival.

Passport: Remember, a valid passport is essential for international travel, with many countries requiring it to be valid for at least six months beyond your intended return date.

Domestic Flights: Plan to arrive at least two hours before your domestic flight to complete check-in and security procedures comfortably.

Online Check-In: Some airlines offer mobile check-in options starting 24 hours before departure, which can expedite the process. However, certain circumstances, such as traveling with an infant on your lap, may still require you to check in at the airline counter.

International Flights: For international departures, arrive at least three hours early to accommodate check-in, customs, and additional security checks. Ensure all necessary documents are current and easily accessible to prevent any delays.

Understanding Customs and Immigration Wait Times

As one of the key international gateways in the Midwest, STL manages a range of flights from domestic to several international destinations. Wait times vary depending on flight schedules, passenger volume, and staffing levels. For international arrivals, STL operates customs and immigration checkpoints efficiently, but it's advisable to allow ample time for processing, especially during peak travel periods. Checking real-time flight information and using mobile apps can provide updates on wait times, helping you plan accordingly. For departures, pre-clearance options may expedite customs procedures at select international destinations, streamlining the departure process from STL.

Average Wait Time to Get Through Security

The average wait time to get through security at St. Louis Lambert Airport (STL) can vary based on the time of day, day of the week, and passenger volume. On average, travelers report wait times of up to ten minutes. However, during peak travel periods, such as early mornings and evenings, wait times tend to be longer as more flights depart and arrive. TSA PreCheck and CLEAR programs are available at STL, which can expedite the security screening process for eligible travelers.

Peak Hours and Off-Peak Hours

Peak hours at St. Louis Lambert Airport (STL) are early mornings (around 5:00 AM to 8:00 AM) and late afternoons to evenings (from about 4:00 PM to 7:00 PM). During these times, the airport experiences higher passenger volumes due to the number of flights departing and arriving. Off-peak hours at STL are generally late mornings to early afternoons and late evenings. Specifically, between 10:00 AM and 3:00 PM, and after 8:00 PM, passenger traffic tends to be lighter. Travelers departing or arriving during these times may experience shorter security lines and quicker check-in processes compared to peak hours.

Navigating Security Checkpoints Efficiently

While security waiting times vary depending on factors outside of your control, you can speed up the process by ensuring that you are prepared. Make sure you have your boarding pass and identification (such as a driver's license or passport) easily accessible and valid. Pack liquids and gels following TSA regulations and dress in attire that makes it easy to remove your shoes and wear minimal metal accessories.

Familiarizing Yourself with TSA Guidelines and Procedures

Familiarizing yourself with TSA guidelines and procedures is essential for a smooth travel experience through St. Louis Lambert Airport. Pack liquids, gels, and aerosols in containers of 3.4 ounces or less, all fitting into a quart-sized clear plastic bag. Ensure that you do not travel with prohibited items, such as aerosol cans and sharp knives. Keep in mind the rules regarding laptops and large electronics, which must be removed from your bag and placed in a separate bin for screening. If you travel regularly, you might want to consider enrolling in TSA PreCheck or CLEAR for expedited security lanes if eligible.

TSA Pre-Check: Benefits and How to Enrol

If you travel frequently, it’s worth exploring TSA PreCheck, which offers significant benefits for travelers passing through security checkpoints at St. Louis Lambert Airport (STL) and other participating airports across the United States. This expedited screening program allows eligible passengers to enjoy shorter wait times, as they do not need to remove shoes, belts, light jackets, laptops, and compliant liquids from carry-on bags. To enroll in TSA PreCheck, applicants must complete an online application on the TSA website, schedule an in-person appointment at an enrollment center, and undergo a background check and fingerprinting. Once approved, travelers receive a Known Traveler Number (KTN) that can be added to their airline reservations, granting access to TSA PreCheck lanes for five years. The enrollment fee is $85, and many credit cards and loyalty programs offer reimbursement for this cost.

The Best Parking Options for Getting There on Time

The airport has seven different airport parking options with varying features and price points. Both terminals have large garage facilities within walking distance, while long-term lots are a shuttle bus ride away. If you want to ensure you arrive on time, the short-term and long-term garages are your best option. 

Comparing Parking Lots

For those who prioritize convenience over price, the Terminal 1 Parking Garage and Terminal 2 Parking Garage are the best options. Both are situated within walking distance of major airlines. Terminal 1 is best for airlines such as Air Canada, Alaska Airlines, Delta, and American Airlines, while Terminal 2 is closer to Charter Flights and Southwest Airlines. 

If you’re less bothered about being within walking distance of the airport but would prefer to keep your car close, Lot A is an excellent option. Shuttle services run every 8-15 minutes and prices are slightly cheaper than the terminal garages. 

Lot B is the best option for long-term parking with a daily rate of $12. Located conveniently for extended stays, shuttles run every 8-15 minutes. Meanwhile, Lot C offers covered and non-covered options at daily rates of $12 and $10 respectively, catering to various vehicle sizes with shuttle services every 8-15 minutes and similar payment options.

Those seeking the best deals should stick to Lot D, which offers the lowest daily rate of $9. Shuttles run every 10 minutes. Lot E, located east of Terminal 2, is the newest parking lot. Rates are similar to the terminal garages, but it’s worth checking availability early due to high demand.

Choosing Between Long-Term and Short-Term Parking

There is no dedicated short-term parking lot at St Louis Airport, though if you are only picking up passengers you can use the Cell Phone lots. For anything longer than an hour, it’s best to use the parking lots. Some parking lots, such as Lot D, only offer daily rates, while others offer hourly. For the most cost-efficient parking, long-term parking offers the best value for money.

Most airlines have their own apps too, which all allow travelers to manage their bookings, check-in for flights, access boarding passes digitally, and receive real-time updates on flight statuses, gate changes, and baggage claim details.

Understanding Boarding Procedures and Gate Locations
