Chicago, a vibrant metropolis famed for its stunning architecture, world-class museums, and deep-dish pizza, is a premier destination for travelers. When planning a visit, understanding the city’s airport landscape is crucial. While O’Hare International Airport often receives the most attention, Chicago Midway International Airport (MDW) serves as a vital and often more convenient gateway for many domestic and even some international travelers. Known for its accessibility and typically smoother travel experience, Midway caters to a specific segment of the airline industry, primarily focusing on low-cost carriers and point-to-point travel. This article delves into the airlines that operate out of MDW, exploring their reach, services, and what makes flying from this historic airport a unique experience.

Midway International Airport: A Strategic Hub for Travelers
Chicago Midway International Airport, often simply referred to as Midway, holds a significant place in aviation history and continues to be a crucial part of Chicago’s transportation infrastructure. Located just eight miles southwest of The Loop, Chicago’s central business district, MDW offers unparalleled convenience for travelers heading to the city center or its southern and western suburbs. Its compact size compared to O’Hare often translates into shorter walks between gates, quicker security lines, and more efficient baggage claim processes, making it a favorite for those prioritizing speed and ease.
The airport’s strategic location and operational efficiency have historically attracted airlines looking to serve the Chicago market with a distinct focus. While it doesn’t boast the extensive international network of O’Hare, Midway excels in providing direct, affordable connections to a wide array of domestic cities, predominantly across the United States. Its role as a major base for certain carriers has shaped its character, offering a streamlined travel experience that often contrasts with the sprawling nature of larger international hubs. This focus on direct flights and efficient turnaround times has cemented Midway’s reputation as an excellent choice for business travelers and leisure seekers alike, who value convenience and competitive fares.
The Dominant Players: Major Airlines at MDW
The airline landscape at Midway is characterized by a few key carriers that have made the airport a cornerstone of their operations. Unlike multi-airline hubs like O’Hare which host nearly every major global carrier, MDW’s tenant list is more curated, primarily featuring airlines that align with its operational model of efficient, point-to-point travel.
Southwest Airlines: The Unrivaled Presence
Without a doubt, Southwest Airlines is the undisputed king of Midway Airport. It operates the vast majority of flights from MDW, effectively using it as one of its busiest and most important hubs. Southwest is renowned for its low-cost model, excellent customer service, and unique boarding process, but perhaps most famously, for its policy of allowing two free checked bags per passenger. This makes it an incredibly attractive option for families, long-term travelers, or anyone needing to carry more luggage without incurring hefty fees.
From Midway, Southwest Airlines offers an extensive network of direct flights to dozens of cities across the United States. Their route map covers major business centers, popular vacation spots, and countless other destinations, making it possible for travelers to reach almost any corner of the country with a single direct flight or a convenient connection through another Southwest hub. The airline’s robust presence at MDW means frequent departures throughout the day, providing flexibility for passengers to choose flight times that best suit their schedules. For many flying out of Chicago Midway, their journey begins and ends with Southwest.
Delta Air Lines and Allegiant Air: Key Contributors
While Southwest dominates, other significant airlines also maintain a presence at Midway, offering alternative options and catering to different travel needs.
Delta Air Lines, one of the “legacy carriers,” operates a limited but important schedule out of MDW. Unlike its massive operations at other hubs, Delta at Midway primarily focuses on connecting passengers to its main hubs, such as Atlanta Hartsfield-Jackson International Airport or Detroit Metropolitan Airport. This provides passengers with access to Delta’s extensive domestic and international network, making it a viable option for those who prefer a full-service airline experience or need to connect beyond Southwest’s reach. While not as frequent, Delta’s flights from Midway are valuable for travelers seeking specific connections or loyalty program benefits.
Allegiant Air also holds a niche at Midway. Known for its ultra-low-cost model, Allegiant specializes in offering non-stop flights to smaller, leisure-focused destinations, often in warmer climates. Their strategy typically involves flying less frequently to these locations, perhaps only a few times a week, but at very competitive prices. This makes Allegiant an excellent choice for vacationers looking for direct access to popular tourist spots that might not be served by other carriers from MDW. Destinations in Florida, Arizona, and other sunbelt states are common on Allegiant’s route map from Midway, catering to the leisure traveler seeking an escape.
Frontier Airlines and Porter Airlines: Expanding Your Options
Rounding out the current roster of airlines at Midway are Frontier Airlines and Porter Airlines, each bringing a distinct flavor to the airport’s offerings.

Frontier Airlines, another ultra-low-cost carrier, provides a further option for budget-conscious travelers. Similar to Allegiant, Frontier focuses on offering highly competitive base fares, with additional services (like seat selection, carry-on bags, and checked luggage) available for an extra cost. Their route network from MDW often overlaps with some of Southwest’s and Allegiant’s destinations but also includes unique routes, particularly to other leisure-oriented cities and growing markets. For travelers who are adept at packing light and customizing their travel experience, Frontier can offer significant savings.
Porter Airlines stands out as a unique presence at Midway, being the sole carrier providing international service from the airport. Porter primarily connects Chicago Midway to Billy Bishop Toronto City Airport (YTZ) in Toronto, Canada. This service is particularly appealing to business travelers and tourists heading to downtown Toronto, as Billy Bishop Airport is located on an island minutes from the city’s financial district and major attractions. Porter is known for its distinctive turboprop aircraft, excellent service, and complimentary amenities like snacks and beverages on board, offering a more refined experience than many budget carriers. Its presence ensures that Midway isn’t exclusively a domestic airport, providing a crucial link to a major Canadian city.
Planning Your Trip from Midway: Tips and Considerations
Choosing to fly out of Midway comes with several advantages, but a well-planned trip requires understanding its unique aspects. From getting to the airport to navigating its terminals, a little preparation can enhance your travel experience significantly.
Navigating MDW: Check-in and Security
Midway’s compact design is one of its greatest assets. The single terminal building, with its three concourses (A, B, and C), makes for relatively straightforward navigation. All airlines operate from this one terminal, with check-in counters located on the main level. Security checkpoints are typically efficient, though, like any airport, they can experience surges during peak travel times. Arriving at least 90 minutes to two hours before a domestic flight and two to three hours for international travel (though Porter to Canada often requires less lead time than major international flights) is always a good rule of thumb. Utilizing services like TSA PreCheck or Clear can further expedite your passage through security, making the already quick process at MDW even faster.
Ground Transportation Options
One of Midway’s most compelling features is its direct connection to Chicago’s public transportation system. The CTA Orange Line provides rapid transit directly from the airport to The Loop and several other Chicago neighborhoods, offering an incredibly cost-effective and efficient way to reach the city center without battling traffic. The Orange Line station is conveniently located within the airport terminal, accessible via a covered walkway.
For those preferring private transport, taxis and rideshare services like Uber and Lyft are readily available. Designated pickup and drop-off areas are clearly marked. Car rental services are also housed in a consolidated facility, accessible via a free shuttle bus from the terminal, simplifying the process of picking up or returning a vehicle. The close proximity of Midway to downtown Chicago generally means shorter travel times and lower fares for these services compared to O’Hare.
Booking Your Flight: Tips for Best Deals
Given the competitive landscape at Midway, especially with the strong presence of low-cost carriers, finding good deals is often achievable.
- Book in Advance: As with most flights, booking several weeks or months ahead typically yields better prices, particularly for popular routes.
- Be Flexible with Dates: Mid-week flights (Tuesday, Wednesday) are often cheaper than weekend travel. Using flexible date search tools can reveal significant savings.
- Understand Fare Structures: Be aware that ultra-low-cost carriers like Frontier and Allegiant charge extra for services like seat selection, carry-on bags, and checked luggage. Factor these into your total cost when comparing with Southwest, which includes two free checked bags, or Delta, which has varying baggage policies depending on fare class and loyalty status.
- Sign up for Fare Alerts: Many airline and travel booking websites offer email alerts for price drops on specific routes.
- Consider Loyalty Programs: If you frequently fly with one of the carriers at MDW, joining their loyalty program can earn you points, status, and sometimes perks like free checked bags or priority boarding.

Beyond the Flight: Amenities and Services at MDW
While smaller than O’Hare, Midway doesn’t skimp on amenities to ensure a comfortable and convenient experience for travelers. The airport has undergone significant upgrades in recent years, enhancing its retail and dining options.
Travelers will find a variety of eateries, from quick-service cafes to sit-down restaurants offering local Chicago favorites and international cuisine. There are also several shops selling everything from last-minute travel necessities and souvenirs to books and fashion items. Free Wi-Fi is available throughout the terminal, allowing passengers to stay connected. Charging stations are increasingly common, ensuring electronic devices remain powered up for the journey ahead.
For those requiring assistance, MDW is fully accessible, with services for passengers with disabilities, including accessible restrooms and wheelchairs. Family restrooms and nursing rooms are also available, catering to the needs of travelers with young children. While Midway might not have the extensive lounge offerings of a major international hub, it provides all the essential services and comforts expected of a modern airport, maintaining its reputation for efficiency without sacrificing passenger experience.
In conclusion, Chicago Midway International Airport serves as an excellent choice for travelers prioritizing convenience, efficiency, and competitive fares. With Southwest Airlines as its anchor, complemented by the specialized services of Delta Air Lines, Allegiant Air, Frontier Airlines, and Porter Airlines, MDW offers a diverse range of domestic and a valuable international connection to Canada. Understanding which airlines fly out of Midway allows travelers to make informed decisions, ensuring a smooth and enjoyable journey to or from the Windy City.
