How Nonstop vs. Connecting Flights Change Your Total Travel Time

Here’s how the options compare:

For most people leaving from Atlanta, a nonstop flight is the most efficient choice. Given ATL’s status as a major hub, nonstop options are usually easy to find throughout the day.

Time You Should Budget on Each Side of the Flight

The flight time is only part of the story. From an Atlanta traveler’s perspective, your door-to-door time includes:

1. Getting to Atlanta Airport (ATL)

Depending on where you are in metro Atlanta:

• Intown (Midtown, Downtown, East Atlanta, Westside):
  Around 20–35 minutes by car in light traffic, but allow 45–60+ minutes during rush hours.
• North Atlanta / Perimeter / Sandy Springs / Dunwoody:
  Often 35–60 minutes, longer if you hit heavy I-285 or GA-400 traffic.
• Further suburbs (Alpharetta, Marietta, Lawrenceville, McDonough, etc.):
  Often 45–75+ minutes, depending on the time of day.

Public transit option:

• MARTA Train to ATL:
  The Red and Gold Lines go directly to the Airport Station, attached to the Domestic Terminal.
  • From Five Points: roughly 20 minutes
  • From Buckhead: roughly 30–35 minutes
    This often gives you more predictable timing than driving at rush hour.

2. Airport Arrival and Security at ATL

For a domestic flight from Atlanta to Chicago, common guidance is to arrive:

• At least 2 hours before departure
• Consider 2.5 hours if:
  • You’re checking bags
  • You’re unfamiliar with ATL
  • You’re traveling at a busy time (early morning, Sunday evening, holidays)

Security line times at ATL can vary, especially at:

• Main Security Checkpoint (Domestic Terminal)
• North Security Checkpoint
• South Checkpoint, which sometimes is less crowded but may not serve all airlines

If you have TSA PreCheck, CLEAR, or both, your time from curb to gate can be much shorter, but it’s still safer not to cut it close.

3. In Chicago: Deplaning, Baggage, and Transit

Once you land in Chicago:

• Taxiing and deplaning: 10–25 minutes is common
• Baggage claim: 15–30 minutes after landing, if you checked a bag

  • From ORD to Downtown Chicago: ~30–60 minutes by train (Blue Line) or car, depending on traffic
  • From MDW to Downtown Chicago: ~25–45 minutes by train (Orange Line) or car

Factors That Can Make the Flight Longer or Shorter

Even on a short route like Atlanta to Chicago, several variables affect your actual time in the air and overall journey.

Weather

• Summer thunderstorms in the Southeast and Midwest can cause:
  • Departure delays at ATL
  • Holding patterns or rerouting near Chicago
• Winter snow and ice can slow operations in Chicago, especially at ORD.

Time of Day and Congestion

Both ATL and ORD are busy hubs, so:

• Early morning flights can be less affected by cascading delays from earlier flights
• Midday and late afternoon flights may be more prone to delays during busy periods
• Evening flights can sometimes face “ground stops” or flow control if storms pass through

Air Traffic Routing

Airlines and air traffic controllers may adjust:

• The route between Atlanta and Chicago for weather or congestion
• Altitude and speed, which can slightly change the flight duration (for example, tailwinds vs. headwinds)

Which Chicago Airport Is Faster From Atlanta: O’Hare or Midway?

From an Atlanta traveler’s perspective, both Chicago airports can be reached in roughly the same flight time, but your ground time in Chicago may differ depending on where you’re headed.

Flying ATL to Chicago O’Hare (ORD)

• Typical flight time: about 1 hour 50 minutes to 2 hours 5 minutes
• Best if you:
  • Have an onward connection on a major airline
  • Are staying near the North or Northwest suburbs of Chicago

The choice between ORD and MDW usually comes down to your airline, price, and where you’re staying in Chicago, rather than major differences in air time.

When to Arrive at Hartsfield-Jackson (ATL) for Your Chicago Flight

For a domestic flight from ATL to Chicago, a good rule of thumb:

• 2 hours early: Minimum for most Atlanta-based travelers
• 2.5 hours early: Safer during:
  • Monday mornings
  • Thursday and Sunday evenings
  • Holidays and school breaks
  • Big events in Atlanta that increase airport traffic

If you’re starting from farther out in the metro area, consider:

• Building in extra drive time for I-75, I-85, I-285, and GA-400 traffic
• Using MARTA to avoid parking and rush-hour gridlock, especially from:
  • Downtown (Five Points, Peachtree Center)
  • Midtown
  • Buckhead
  • Doraville / Chamblee / Brookhaven (Gold Line)
  • Sandy Springs and North Springs (Red Line)

Tips to Make the ATL → Chicago Trip Smoother

Here are some Atlanta-focused strategies to keep your trip close to the “ideal” timeline:

1. Choose Your Departure Time Wisely

• Early morning departures from ATL often:
  • Have fewer delays
  • Encounter lighter traffic driving to the airport
• If you must fly later in the day, allow extra buffer time for both traffic and possible delays.

2. Use the Right Terminal and Checkpoint at ATL

From Atlanta:

• Verify whether your airline uses the Domestic Terminal (North or South) or the International Terminal (Concourse F) for check-in, even for domestic flights.
• If you’re flying a domestic route like ATL → Chicago, most travelers will check in at the Domestic Terminal.

Security options:

• Main Checkpoint (between North and South): Typically the busiest
• North or South Checkpoint: May be faster depending on time and airline
• TSA PreCheck / CLEAR lanes: Can significantly reduce wait times

3. Consider Checked Bags vs. Carry-On

For a short route like Atlanta to Chicago:

• Carry-on only can:
  • Shorten your time at ATL check-in
  • Reduce waiting at baggage claim in Chicago
• Checked bags may make sense if:
  • You’re packing for a long stay or winter in Chicago
  • You want to avoid carrying heavy bags through ATL’s large concourses and Plane Train system
