If you’re looking at flights from Atlanta to Buffalo, you’re likely flying out of Hartsfield–Jackson Atlanta International Airport (ATL) and heading to Buffalo Niagara International Airport (BUF).

Key Things to Know About Atlanta–Buffalo Flights

For travelers starting in Atlanta, Georgia, here’s a quick snapshot of this route:

Keeping these basics in mind makes it easier to compare flights and plan connections, especially if you’re tying this trip into a bigger itinerary through Atlanta.

Choosing Flights From Atlanta to Buffalo

Nonstop vs. Connecting Flights

If you’re living in metro Atlanta, you’re probably used to having lots of options through Hartsfield–Jackson, one of the busiest hubs in the world. For the Atlanta to Buffalo route, you’ll typically see:

• Nonstop flights

  • Shortest total travel time (around 2 hours in the air).
  • Often depart from ATL’s domestic terminals (North or South).
  • Good choice if you’re traveling with kids, have limited time, or prefer simplicity.

• One-stop connecting flights

  • May connect through another U.S. hub.
  • Can sometimes be less expensive than nonstop options, especially at off-peak times.
  • Add total travel time due to layovers.

If your schedule is tight—like needing to be in Buffalo for a specific event, game, or interview—nonstop flights usually offer the least risk of delay from missed connections.

Typical Flight Duration and Timing

Most nonstop flights from ATL to BUF:

• Spend around 2 hours in the air.
• Often depart morning to mid-afternoon, with some evening options depending on the day.

If you’re in Atlanta and planning same-day activities once you land in Buffalo (driving to Niagara Falls, checking into a hotel, or heading to a campus), consider:

• Morning departures from ATL to arrive in Buffalo by midday.
• Allowing extra buffer for winter weather on the Buffalo end, especially November through March.

Getting to Hartsfield–Jackson Atlanta International Airport (ATL)

Which Terminal You’ll Use

For flights from Atlanta to Buffalo, you’ll almost always use:

• Domestic Terminal – North or South at ATL
  6000 N Terminal Pkwy
  Atlanta, GA 30320

Your exact check-in area depends on your airline, but all domestic departures to Buffalo leave from the domestic concourses (A–D, T). The Plane Train connects terminals and concourses inside security, so you can quickly reach your gate after security.

Transportation Options From Around Atlanta

Depending on where you’re staying or living in the metro area, you have several ways to get to ATL:

• MARTA Rail 🚆

  • Take the Red or Gold line directly to Airport Station, located inside the Domestic Terminal.
  • Useful if you’re coming from Downtown, Midtown, Buckhead, Doraville, College Park, or near any MARTA rail station.
  • Often the most predictable option during rush hour.

• Driving and Parking

  • On-site parking at ATL includes Hourly, Daily, Economy, Park-Ride lots, and various off-site private lots nearby.
  • If you live in the suburbs (e.g., Marietta, Roswell, Lawrenceville, Fayetteville), driving is often the most convenient option, especially for early morning flights.

• Rideshare and Taxis

  • Rideshare pick-up is well-marked at the Domestic Terminal.
  • Good if you don’t want to leave a car at the airport or are visiting Atlanta temporarily.

Aim to arrive at ATL at least 2 hours before your scheduled domestic departure, especially during peak times (early morning, late afternoon, holidays, and summer).

Booking Smart: Timing, Prices, and Flexibility

When Atlantans Most Often See Higher Fares

On the Atlanta–Buffalo route, prices typically rise around:

• Major winter holidays (Thanksgiving, Christmas, New Year’s).
• Summer travel season (June–August), when Niagara Falls tourism peaks.
• College move-in and graduation periods (Buffalo and nearby universities).

If you’re flexible:

• Look at midweek departures (Tuesday–Thursday), which can sometimes be less expensive than Friday–Sunday travel.
• Consider early morning or late-night flights, which may be cheaper than prime mid-day times.

One-Way vs. Round-Trip From Atlanta

For Atlantans:

• Round-trip tickets are often the simplest if your dates are set.
• One-way tickets can be useful if:
  • You’re continuing deeper into upstate New York or Canada and flying back from somewhere else.
  • You’re not sure how long you’ll stay in the Buffalo/Niagara area.

If you live in Atlanta and travel frequently, consider whether this trip can be combined with other flights through ATL to make better use of your travel budget and time.

What to Expect After Landing in Buffalo

Arriving at Buffalo Niagara International Airport (BUF)

You’ll land at:

• Buffalo Niagara International Airport (BUF)
  4200 Genesee St
  Buffalo, NY 14225

BUF is smaller and easier to navigate than ATL, which many Atlanta travelers find refreshing after leaving such a large hub. Baggage claim, rental car counters, and ground transportation areas are compact and well marked.

Ground Transportation in Buffalo

From BUF, common options include:

• Rental cars
  • Helpful if you’re heading to Niagara Falls, Rochester, Western New York suburbs, or plan to explore multiple spots.
• Taxis and rideshares
  • Available from designated pick-up zones outside the terminal.
• Shuttle services
  • Many hotels in the Buffalo area offer airport shuttles—check with your lodging ahead of time.

Plan your ground transport with weather and season in mind. In winter, snow and ice can slow driving times around Buffalo and upstate New York, so leave extra time if you’re connecting to an event or tour.

Packing and Weather: Leaving Atlanta for a Colder Climate

Atlanta travelers heading to Buffalo often underestimate the temperature difference, especially in winter.

• Winters in Buffalo
  • Colder and snowier than Atlanta.
  • Consider packing: a warm coat, waterproof shoes or boots, gloves, hat, and layers.
• Summers
  • Warm, but often less humid than Atlanta.
  • Light layers and a light jacket for evenings can be helpful, especially if you’re visiting the Niagara Falls area, where mist and wind can make it feel cooler.

Keep your essential winter layers in your carry-on if you’re traveling in colder months. That way you’ll have them immediately when you walk out of BUF, even if your checked bag is delayed.

Atlanta-Specific Tips for a Smooth Trip

Give Yourself Time to Navigate ATL

Even if you’re used to flying out of Hartsfield–Jackson, it’s easy to underestimate:

• Security lines at peak times.
• Transit time from parking or MARTA to your gate.
• Walking time once inside, especially to concourses further down the line.

✅ Local tip: If you live in Atlanta’s northern suburbs and drive to ATL, consider extra buffer time for traffic on I-75/I-85, especially during weekday morning or late afternoon rush hour.

Using ATL’s Amenities Before Your Flight

Because Buffalo flights are relatively short, many travelers prefer to:

• Eat a full meal in ATL’s main food courts or concourse restaurants before departure.
• Charge devices at gate-area charging stations.
• Pick up last-minute winter gear (gloves, hat) if you forgot them, especially when leaving Atlanta during a warm spell for a cold Buffalo winter.

Connecting Through Atlanta to Reach Buffalo

Some travelers may be starting somewhere else and connecting through ATL on the way to Buffalo. If you’re in this situation and trying to understand how it works:

• All Buffalo flights will depart from a domestic concourse at ATL (T, A, B, C, or D).
• If you’re connecting from an international arrival, you’ll likely:
  • Clear U.S. customs and immigration in Atlanta.
  • Re-check bags.
  • Go through security again and then take the Plane Train to your domestic departure concourse.

For tight connections, try to:

• Sit forward in the plane on your inbound flight for faster deplaning.
• Check your departure gate on airport monitors or mobile apps as soon as you land, in case of changes.

When Atlantans Might Choose Buffalo Over Other Airports

If you’re planning a trip from Atlanta to the Niagara region or Western New York, BUF can be a strategic arrival airport because:

• It’s relatively close to Niagara Falls, NY and easily accessible by car.
• It’s a manageable drive to Rochester, some parts of Ontario, Canada (via border crossings), and smaller towns in the region.
• It offers a simpler airport experience compared with some larger Northern airports.

If you’re based in Atlanta, consider whether flying to Buffalo and renting a car fits better than trying to get closer by connecting elsewhere and driving longer distances.

Practical Next Steps for Atlanta Travelers

1. Decide your dates and flexibility.

2. Choose your preferred flight type.

   • Nonstop for speed and simplicity, or one-stop if you’re prioritizing price or timing.

3. Plan how you’ll get to ATL.
