Flying From Atlanta to Houston: A Practical Guide for ATL Travelers

Flying from Atlanta to Houston is one of the easiest and most common routes out of Hartsfield–Jackson Atlanta International Airport (ATL). Whether you live in metro Atlanta, you’re here on business, or you’re connecting through the city, this guide breaks down what you need to know to plan a smooth trip to Houston.

Overview: Atlanta–Houston Flight Basics

For most travelers in Atlanta, flights to Houston are:

• Nonstop from ATL to both major Houston airports
• Short (around 2–2.5 hours in the air)
• Frequent throughout the day
• Served by multiple major U.S. airlines

You’ll typically fly:

• From: Hartsfield–Jackson Atlanta International Airport (ATL)
• To:
  • George Bush Intercontinental Airport (IAH) – North Houston, major hub
  • William P. Hobby Airport (HOU) – Closer to downtown and southeast Houston

If you’re based in Atlanta, you’ll enjoy strong nonstop options, especially because ATL is a major U.S. hub.

How Long Is the Flight From Atlanta to Houston?

Nonstop flights from Atlanta (ATL) to Houston (IAH or HOU) generally take:

• Approximate flight time:2 hours to 2 hours 30 minutes in the air
• Gate-to-gate time: Often closer to 3+ hours when you include taxiing and boarding

Time zone note:

• Atlanta (Georgia) is in the Eastern Time Zone (ET)
• Houston (Texas) is in the Central Time Zone (CT)
• Houston is 1 hour behind Atlanta

So if you leave ATL at 4:00 p.m. ET, you may land around 5:00 p.m. CT, even though you’ve been in the air about 2 hours.

Which Atlanta Airport Do You Use?

Houston Airports: IAH vs. HOU

When searching for flights from Atlanta to Houston, you’ll see two main destination airports. Both are usable from ATL, but they serve different sides of the city and suburbs.

George Bush Intercontinental Airport (IAH)

• Location: North Houston, roughly 20–25 miles from downtown
• Best for:
  • Connections on a major carrier
  • Travelers staying in North Houston, The Woodlands, or near major business campuses
• Travel time to city: Often 30–60 minutes by car, depending on traffic

William P. Hobby Airport (HOU)

• Location: Southeast of downtown Houston, closer in
• Best for:
  • Travelers staying near downtown, the Medical Center, or the southeast side
  • Those who prefer a smaller, easier-to-navigate airport
• Travel time to city: Often 15–35 minutes by car, depending on traffic

When you’re choosing flights from Atlanta:

• If you value quick access to central Houston, look for flights into HOU.
• If you’re connecting onward or staying in North Houston, IAH may be more convenient.

Typical Flight Options From Atlanta to Houston

From Atlanta, you’ll find:

• Nonstop flights throughout the day to both IAH and HOU
• Early morning, midday, and evening departures, useful for work trips or weekend getaways
• A mix of mainline jets (larger planes) and regional jets, depending on time and airline

Most Atlanta-based travelers can:

• Leave Atlanta in the morning
• Have midday or early afternoon meetings in Houston
• Fly back the same evening if needed, thanks to the short flight time and time zone advantage

3. Clear TSA security
4. Ride the Plane Train to the correct concourse

Weather Differences

Atlanta and Houston share some similarities: both can be humid and hot in summer. But there are some planning considerations:

• Summer: Houston can feel even more humid than Atlanta; pack breathable clothing.
