When to Arrive for MDW Security Check-In?

Each airline establishes its own check-in policies. Nevertheless, travelers should adhere to these general guidelines:

• For domestic flights, you must arrive at least two hours early.
• For international flights, you need to arrive at least three hours before departure.

Ultimately, arriving early ensures you have ample time to check your bags, complete the airline check-in process, and pass through TSA security comfortably, thereby avoiding any last-minute rushing.

MDW Airport Check-In Options:

Midway International Airport (MDW) is primarily served by Southwest Airlines, as well as Delta Air Lines, Porter Airlines, Frontier Airlines, and Volaris.

Here are the main check-in options available to travelers at MDW Airport:

1. Counter Check-In (Upper Level):

The airline ticketing and check-in counters sit on the Upper Level of the single terminal. First, use this option if you have checked baggage. 

Additionally, it suits passengers who need special assistance, are traveling with infants, or are carrying international documents. Therefore, arrive at least two hours early for domestic flights and three hours early for international departures.

2. Online/Mobile Check-In:

Most airlines at MDW Airport, including Southwest and Delta, offer mobile check-in 24 hours before departure. You can simply use the airline’s website or app to check in, choose your seat, and get a digital or printable boarding pass. Then, if you carry only hand luggage, head straight to security. However, if you check bags, stop at the bag drop.

3. Self-Service Kiosks:

Self-service kiosk technology powers the check-in experience for airlines like Southwest and United at MDW Airport. To begin, the passenger locates and engages their airline’s touchscreen device. Next, to access their flight details, users enter a confirmation code, loyalty number, passport number, or mobile pass.

Once verified, the kiosk offers a comprehensive suite of functions, including generating boarding passes, printing and facilitating payment for bag tags, allowing passengers to modify seat selections, and updating essential data such as a KTN. Therefore, this system dramatically reduces wait times and shortens standard check-in lines.

4. Curbside Check-In:

MDW Airport’s Curbside check-in availability depends on your airline. Some carriers may offer this service, while others may not.

To confirm:

• Visit your airline’s official website
  
• Call the airline’s reservation number.
  
• Check the airline links listed on the MDW airlines page.
  

Therefore, always verify curbside options in advance to avoid last-minute confusion.

Essential MDW Security Travel Tips:

You can speed up the MDW security check-in process by preparing before you reach the checkpoint:

• Make sure your luggage does not include any prohibited items.
  
• Keep your valid ID and boarding pass ready for inspection.
  
• Remove liquids and large electronics, such as laptops, from your carry-on bag.
  
• Take off your shoes, outerwear, and bulky jewelry before screening.
  
• Empty your pockets while you wait in line.
  
• Place all valuable items securely in your carry-on bag.
  

Therefore, these simple steps help TSA officers screen passengers more efficiently and reduce delays.

1. Check for Prohibited Items Before You Fly:

Prohibited items are the primary reason screening takes longer. You can guarantee a faster trip through the checkpoint by checking your belongings beforehand. Use the “When I Fly, Can I Bring My…” tool on TSA.gov,

This tool clearly shows what you can pack in:

• Carry-on baggage
  
• Checked luggage
  

Knowing the rules ahead of time helps you pack correctly and pass through security faster.

2. Understand the TSA 3-1-1 Liquids Rule:

TSA strictly enforces the 3-1-1 liquids rule at MDW Airport security check-in:

• Liquids, gels, aerosols, creams, and pastes must be 3.4 ounces (100 ml) or less
  
• All containers must fit in one quart-size clear plastic bag.
  
• You must place this bag in a screening bin.
  

Therefore, oversized liquids often cause delays, so double-check sizes before heading to the airport.

3. Pack Smart for Faster Screening:

You must pack smart to fly through security. A well-organized carry-on allows TSA officers to visually inspect your bag faster, minimizing delays at the checkpoint. This benefits both you and everyone waiting in line.

4. TSA Cares: Assistance for Travelers With Special Needs:

MDW Airport supports travelers who need extra help during security screening through TSA Cares. This helpline assists passengers with disabilities, medical conditions, and exceptional circumstances.
If you need further support:

• Call (855) 787-2227
  
• Contact at least 72 hours before travel.
  

Moreover, injured service members and veterans, including those connected to wounded warrior programs, can use TSA Cares to facilitate the screening process.

Conclusion:

MDW Airport security check-in becomes far less stressful when you plan and take a few smart steps. First, arrive early to allow enough time for screening, especially during peak travel hours. Next, pack your carry-on according to TSA guidelines to avoid delays at the checkpoint. Additionally, keep your ID and boarding pass easily accessible for quick verification. 

If eligible, use TSA PreCheck to enjoy faster screening with fewer restrictions. Meanwhile, passengers who need extra help can request assistance through TSA Cares.  Overall, preparing in advance ensures a smooth, efficient, and more comfortable security experience at Midway International Airport.
