How Far Is Atlanta From Houston By Plane?

The Quick Answer

Atlanta is approximately 702 miles (1,130 km) from Houston by plane. A nonstop flight takes about 1 hour and 55 minutes gate to gate, with the actual in-air time closer to 1 hour and 35 minutes. This is one of the shortest major-city routes in the country.

It's barely enough time to get comfortable, watch a couple of YouTube videos, and start thinking about what you want for dinner.

Airlines Flying Nonstop

This route is packed with options. Four airlines offer nonstop service:

• Delta Air Lines — About 61 nonstop flights per week (nearly 9 per day). Atlanta is Delta's home base, so they dominate here.
• United Airlines — About 31 nonstop flights per week (4-5 per day). Houston IAH is United's hub.
• Spirit Airlines — About 12 nonstop flights per week. Budget-friendly option if you're traveling light.
• Frontier Airlines — Additional budget carrier option with periodic service.

Between Delta and United alone, you've got well over a dozen nonstop flights every single day. Finding a convenient departure time is never an issue on this route.

Which Houston Airport?

Houston has two airports, and both serve Atlanta:

• George Bush Intercontinental (IAH) — Delta, United, and Spirit fly nonstop to ATL from here. More options overall.
• William P. Hobby (HOU) — Southwest offers connecting service. Some nonstop options available depending on the carrier.

If you want the most nonstop choices, IAH is your best bet. If you live closer to Hobby and don't mind a potential connection, that works too.

Flight Schedule

Flights run from early morning to late evening:

• First departure — Around 5:05 AM from Houston
• Last departure — Around 9:48 PM from Houston
• Peak times — Early morning (6-8 AM) and late afternoon (4-7 PM) have the most options

The earliest flights are great for business travelers who want to get to Atlanta and have a full workday. You can leave Houston at 5 AM, land by 8 AM Eastern, and be in a meeting by 9.

Time Zone Difference

Houston is in the Central time zone and Atlanta is in the Eastern time zone — a 1-hour difference. You'll "lose" an hour flying east to Atlanta, but the flight is so short that the impact is minimal.

Leave Houston at noon Central, arrive in Atlanta around 2:55 PM Eastern. You've been traveling for under 2 hours but the clock jumped almost 3 hours. On the way back, you gain that hour — a 5 PM departure from Atlanta gets you into Houston around 5:55 PM Central.

What Does It Cost?

Short route plus heavy competition equals good prices for travelers:

• Economy round trip — $100 to $300 is typical
• Budget carriers (Spirit/Frontier) — As low as $29-50 each way during sales
• Business/First — $300 to $800 round trip

Getting the Best Price

• Check Spirit and Frontier first for rock-bottom base fares, but factor in bag fees before celebrating
• Southwest doesn't appear on Google Flights — Check their site directly
• Tuesday and Wednesday flights are cheapest
• Book 2-4 weeks out — On short domestic routes, you don't need to book as far in advance
• Same-day changes — Delta and United both allow same-day standby or changes for a fee (or free with elite status)

What to Expect on the Flight

At under 2 hours, this is a quick hop. Here's the reality:

• Seatbelt sign — May stay on for a good chunk of the flight due to the short duration and Southern weather patterns
• Beverage service — You'll get one drink service, maybe snacks. That's it.
• No meal service — Even in first class, expect a snack box at best on this short segment
• Wi-Fi — Available on Delta and United, but barely worth connecting for such a short flight
• Entertainment — Bring your own. Some aircraft have seatback screens, but many don't on short-haul flights.

Honestly, by the time you reach cruising altitude and the seatbelt sign goes off, you're almost starting your descent. Bring a book or podcast and you're set.

Atlanta Airport (ATL) Tips

Hartsfield-Jackson is the busiest airport in the world, but it's actually well-organized:

• The Plane Train connects all concourses underground — fast and efficient
• Domestic terminal has two sides (North and South) — check your terminal before heading to the airport
• MARTA rail connects directly to the airport, making it one of the best-connected US airports for public transit
• Security lines can be long during peak hours — TSA PreCheck saves serious time here

Houston Airport Tips

• IAH — Large airport with 5 terminals connected by the Skyway automated train. Arrive 90 minutes early for domestic flights.
• Parking at IAH is expensive — consider rideshare or the SuperShuttle if you're solo
• HOU (Hobby) — Smaller, easier to navigate, and closer to downtown Houston. Arrive 75 minutes early.

Should You Drive Instead?

The driving distance from Houston to Atlanta is about 790 miles, which takes roughly 11-12 hours. It's doable in a long day, and some people do it to save money or bring more luggage.

But with flights taking under 2 hours and fares often under $100 each way on budget carriers, flying is almost always the smarter choice unless you need a car in Atlanta or are traveling with a group that can split gas costs.

Business Traveler Tips

This is a huge business travel route connecting two major Southern economic hubs. If you're flying for work:

• Early morning flights let you do a full day trip — leave Houston at 6 AM, work in Atlanta, catch a 7 PM flight home
• Delta Sky Club access at both ATL and IAH makes the pre-flight experience much more productive
• United Club at IAH is solid for United loyalists
• Both cities have excellent airport food if you didn't have time to eat — One Flew South at ATL is particularly worth seeking out
