Chicago Midway International Airport uses the IATA identifier MDW to manage millions of commercial passengers every year. Located on Chicago's Southwest Side, MDW operates as a high-density hub primarily serving low-cost carriers like Southwest Airlines. Unlike O'Hare International Airport (ORD), which covers massive acreage on the far Northwest Side, Midway sits just eight miles from the Loop, making it a compact alternative for travelers heading directly into downtown Chicago.
When you look up flight itineraries, track luggage, or print boarding passes, the MDW code ensures your route syncs precisely with global aviation databases. Knowing how to navigate its single terminal building, security checkpoints, and ground transit options saves you time and avoids common logistical headaches.
Understanding the MDW Airport Layout
Midway features a single terminal building split into three concourses—Concourse A, Concourse B, and Concourse C—totaling 43 gates. Because the airport sits on a relatively small footprint compared to other major hubs, the terminal layout is linear and straightforward, though concourses can get crowded during peak departure banks.
- Concourse A: Handles a large share of Southwest departures and arrivals, offering multiple dining options and retail kiosks.
- Concourse B: Houses additional gates, primarily for Southwest and select regional operators.
- Concourse C: Features gates used by various carriers, located adjacent to the central security screening area.
Security screening is consolidated into a single large checkpoint facility located on the ticketing level before the pedestrian bridges leading to the concourses. During early morning rush hours, security queues can back up quickly, so arriving at least two hours before domestic departures is standard practice.
Ground Transportation: Getting from MDW to Downtown Chicago
One of MDW’s biggest selling points is its proximity to the city center. You have several reliable transit choices depending on your budget and luggage load.
The CTA Orange Line
The Chicago Transit Authority (CTA) Orange Line train offers the fastest, most predictable route into downtown. The CTA station sits at the Midway Transportation Center, linked to the airport terminal via an enclosed, climate-controlled pedestrian bridge and escalators.
- Travel Time: Roughly 25 to 30 minutes to downtown stations like Loop, Clark/Lake, or Harold Washington Library.
- Cost: Standard CTA rail fare applies (currently $2.50). You can pay with a Ventra card, contactless credit card, or smartphone payment at the turnstiles.
- Frequency: Trains run roughly every 10 to 15 minutes from early morning until late evening.
Rideshares, Taxis, and Car Rentals
If you prefer door-to-door service, rideshare pickups (Uber and Lyft) and designated taxi stands operate from the lower-level outer curb outside the baggage claim area. Follow the overhead airport signage directing you to the designated rideshare pickup zone.
The Rental Car Center is located off-site, accessible via a dedicated shuttle bus service that picks up passengers from the lower-level curb outside baggage claim. Major rental brands operate out of this facility, providing vehicles for travelers venturing beyond city limits.
Parking Options at Midway
If you're driving to the airport or picking up arriving passengers, MDW offers structured parking facilities connected to the terminal, alongside economy options.
- Garage Parking: Located directly across from the terminal building, the main parking garage offers hourly and daily rates. It provides covered parking and an easy walk to the terminal elevators.
- Economy Parking Lot: Situated further away with dedicated shuttle service running 24/7 to the terminal lower level. It's the most budget-friendly official airport parking choice for multi-day trips.
- Cell Phone Lot: A free waiting area where drivers can park while waiting for arriving passengers to collect their bags, keeping terminal roadways clear of congestion.
