How Long Is the Flight from Atlanta to Las Vegas? A Local’s Guide from ATL to LAS

If you’re in Atlanta and planning a trip to the Las Vegas Strip, you’re probably asking a simple but important question: How long is the flight from Atlanta to Las Vegas?

While the answer is fairly straightforward, your actual gate-to-gate and door-to-door time can vary a lot depending on the airline, time of day, and airport logistics at Hartsfield–Jackson Atlanta International Airport (ATL).

The Short Answer: Flight Time from Atlanta to Las Vegas

For a nonstop flight from Atlanta (ATL) to Las Vegas (Harry Reid International Airport – LAS):

• Average nonstop flight time:4 to 4.5 hours
• Distance: About 1,740–1,800 miles (varies by route)
• Time zone change: Las Vegas is 3 hours behind Atlanta (Eastern vs. Pacific Time), which can make the trip feel shorter on the clock.

You’ll usually see airlines list the scheduled flight duration as around 4 hours 10 minutes to 4 hours 30 minutes. Actual time in the air may be slightly less or more depending on:

• Winds and weather
• Air traffic congestion
• Runway and taxi delays at ATL or LAS

Typical Atlanta–Las Vegas Flight Options

Most trips from Atlanta to Las Vegas fall into two main categories: nonstop and one-stop.

Nonstop Flights

Nonstop flights are the fastest and most convenient for travelers starting in metro Atlanta.

• Typical duration: About 4–4.5 hours in the air
• Ideal for: Short trips, weekend getaways, business travel, or anyone who wants to avoid layovers

You’ll usually be flying directly from ATL to LAS without changing planes or airports, which simplifies the journey, especially if you aren’t a frequent flyer.

One-Stop or Connecting Flights

If you can’t find a nonstop option that fits your schedule or budget:

• Typical total travel time:6 to 9+ hours (including layover)
• Common connection cities: Dallas, Houston, Denver, Phoenix, Charlotte, Chicago, and others

These flights may include:

• One flight from Atlanta to a hub city
• A second flight from that hub to Las Vegas

While this can sometimes reduce ticket cost, it increases:

• Total in-air time
• Layover time
• Chance of delays or missed connections

For most Atlanta travelers, a nonstop flight is usually the better balance of time and convenience for this route.

How Atlanta Travelers Can Choose the Best Flight Time

For someone living in or visiting Atlanta, here are practical tips for picking a flight to Las Vegas that fits your schedule.

Think About Your Schedule in Eastern Time and Pacific Time

Because Las Vegas is 3 hours behind Atlanta, your body may still feel like:

• 7:00 p.m. in Vegas = 10:00 p.m. in Atlanta
• Midnight in Vegas = 3:00 a.m. in Atlanta

If you have evening plans in Vegas on your arrival day, consider:

• Mid-morning or midday departure from ATL, arriving in Vegas early afternoon local time
• Avoid very late departures from Atlanta if you don’t handle time changes well

Consider Your Transportation to ATL

From around metro Atlanta:

• Downtown / Midtown / Buckhead: Plan 30–60 minutes to ATL by car or ride share, depending on traffic
• North suburbs (Sandy Springs, Roswell, Alpharetta): Plan 45–75 minutes in heavier traffic periods
• Southside communities (College Park, East Point, Forest Park): Often 15–30 minutes, but still build in cushion

If you use MARTA:

• The Airport Station is directly connected to the domestic terminal
• Add time for:
  • Driving or ride share to your MARTA station
  • Waiting on a train
  • Riding time to the airport

This ground time is easy to underestimate when you’re focused on the flight duration alone.
