ATL to Chicago: Which Airports You’ll Use

Departing from Atlanta: Hartsfield–Jackson (ATL)

Nearly all commercial flights from Atlanta to Chicago leave from:

Hartsfield–Jackson Atlanta International Airport (ATL)
6000 N Terminal Pkwy
Atlanta, GA 30320
General info: 800-897-1910

Key points for Atlanta travelers:

• Terminals & concourses:
  • Check your airline and gate before you leave home.
  • Domestic flights depart from the Domestic Terminal (North or South), then connect via the Plane Train to concourses A–E (and T by walking).
• Time to arrive:
  • For domestic flights to Chicago, aim to arrive 2 hours before departure, especially at peak times (early morning and late afternoon).
• Ground transportation to ATL:
  • MARTA: Airport station on the Red and Gold lines connects directly into the Domestic Terminal (great from Midtown, Downtown, Buckhead, Doraville, College Park, etc.).
  • Rideshare/taxi: Dedicated pick-up/drop-off areas at ATL; good option from the suburbs.
  • Parking: On-site economy and park-ride lots, plus many off-airport parking facilities around Airport Blvd and surrounding areas.

If you’re staying downtown or in Midtown, riding MARTA to the airport is often the most predictable way to avoid traffic on I‑75/85.

Arriving in Chicago: O’Hare vs. Midway

When searching Atlanta to Chicago flights, you’ll see two airport options. For someone starting in Atlanta, your choice affects your overall travel time and cost once you land.

Chicago O’Hare International Airport (ORD)

• Larger, major hub with more flight options and connections.
• Located northwest of downtown Chicago.
• Connected to downtown by the CTA Blue Line train and multiple bus and shuttle services.
• Often used by travelers continuing to other U.S. or international destinations.

Best for:

• Travelers from Atlanta connecting to another flight
• Those staying in Chicago’s North Side or suburbs north/west of the city
• People who prioritize more departure time choices

Chicago Midway International Airport (MDW)

• Smaller than O’Hare, often easier to navigate.
• Located southwest of downtown Chicago.
• Connected to downtown by the CTA Orange Line train.
• Can be closer to some neighborhoods and certain suburbs.

Best for:

• Quick trips where you value shorter walks inside the terminal
• People staying in downtown Chicago or on the South/Southwest Sides
• Travelers who prefer a less overwhelming airport experience

If you’re flying from Atlanta for a weekend trip, Midway’s size and easier layout can be a big plus, while O’Hare typically offers more flight times throughout the day.

Typical Flight Times and Daily Schedules from Atlanta

Because ATL is one of the busiest airports in the world, Atlanta–Chicago flights operate throughout the day.

You can generally expect:

• First flights out: Often around 6:00–7:00 a.m. from ATL
• Last nonstop flights: Often early to mid-evening, though options vary by airline and day
• Peak travel windows:
  • Early morning (6–9 a.m.)
  • Late afternoon and early evening (3–7 p.m.)

If you need to be in Chicago by morning from Atlanta, consider:

• Taking a very early nonstop from ATL; or
• Flying up the night before and staying near downtown or the airport.

Cost Factors for Flights from Atlanta to Chicago

Prices on the Atlanta to Chicago route can change based on:

• Time of booking:
  • Booking 1–3 months in advance for leisure travel usually offers better options than last-minute purchases.
• Day of the week:
  • Midweek flights (Tuesday–Thursday) are often more affordable than peak Friday/Sunday schedules.
• Time of day:
  • Early morning and late-night flights can sometimes be cheaper than midday departures.
• Airport choice:
  • You may see slight price differences between ORD and MDW depending on the airline and schedule.

If you live in metro Atlanta and your schedule is flexible, it can help to:

• Try different days of the week (e.g., shifting a Friday-to-Sunday trip to Thursday-to-Saturday).
• Compare very early or late departures from ATL vs. midmorning flights.

When Atlanta Travelers Should Arrive at the Airport

Because ATL is such a busy hub, especially on business routes like Atlanta–Chicago, plan your timing carefully.

Recommended arrival times at ATL

• Domestic flight with checked bags: Arrive 2 hours before departure.
• Carry-on only, TSA PreCheck, off-peak time:
  • You might be comfortable with 75–90 minutes, but 2 hours is still safer in case of traffic or long security lines.
• Holiday periods or Monday morning rush:
  • Give yourself extra buffer; aim for 2+ hours.

The North and South Security Checkpoints can sometimes have very different wait times. If you’re local, using the MARTA Airport Station can help you avoid parking and ground traffic delays altogether.
