Nonstop vs. Connecting Flights from Atlanta to Milwaukee

Nonstop flights

If you live in the Atlanta area or are staying near downtown, nonstops out of ATL are almost always the best balance of time and convenience.

Connecting flights

You’ll sometimes see one-stop itineraries from Atlanta to Milwaukee, especially:

• At off-peak times
• On certain airlines or on busier travel dates
• If nonstop options are sold out or more expensive

For one-stop flights, total travel time is usually:

• 4 to 7+ hours total, depending on layover city and length
• Common layovers might be in Chicago, Charlotte, or another hub city, depending on airline

If you prefer a shorter travel day, filter for “nonstop” when searching flights from ATL to MKE.

Time Zone and Arrival Time: What Atlanta Travelers Should Expect

Atlanta and Milwaukee are in different time zones:

• Atlanta: Eastern Time (ET)
• Milwaukee: Central Time (CT), which is 1 hour behind Atlanta

This means when you fly from Atlanta to Milwaukee:

• If you depart Atlanta at 2:00 p.m. ET, a roughly 2-hour flight might land in Milwaukee around 2:00–2:15 p.m. CT
• It can feel like you “gain” an hour on the clock

On the way back Milwaukee → Atlanta, the opposite is true:
