Delta’s AI Routes 100,000 Bags Daily at World’s Busiest Hub

ATLANTA — Before the plane even arrives, Mike Davis is already on his way to the gate. Behind the wheel of a baggage tug at Hartsfield-Jackson Atlanta International Airport (ATL) — the world’s busiest airport by passenger volume — Davis is guided not by instinct alone, but by an artificial intelligence system built by Delta Air Lines to orchestrate the movement of more than 100,000 bags on a busy day.

On a peak travel day, Delta handles over 100,000 bags in Atlanta alone, with three-quarters of those passing through en route to other destinations. An average of nine airline employees touch each bag somewhere along its journey, according to NPR, which was granted rare behind-the-scenes access to the operation.

The Challenge of the World’s Busiest Airport

ATL has been the world’s busiest airport for 27 of the last 28 years, handling 106.3 million passengers in 2025 — the only airport globally to cross the 100 million mark. Delta’s primary hub sees approximately 40 percent of the airline’s customers pass through daily, and one-fifth of Delta’s total bag volume moves through Atlanta.

“Atlanta is an enormous operation, Delta’s biggest by a long way,” Paul Buckley, Delta’s director of operations in Atlanta, told NPR.

Baggage AI: A Rideshare Algorithm for the Tarmac

To manage this complexity, Delta built an in-house AI platform called “Baggage AI” that functions like a ridesharing app for the 250 ramp agents responsible for moving bags between aircraft. The system uses real-time flight data, bag locations, and connection times to create optimized driving routes for each driver, prioritizing bags with the tightest connections — known as “hot bags.”

According to Delta’s News Hub, the system re-optimizes routes every two minutes based on real-time conditions such as gate changes, flight time adjustments, and tight connections. The airline reports a nearly 30% improvement in bag transfer success rates, translating to thousands more passengers receiving their bags on time.

“Think of it as a rideshare-like app that optimizes routes for our baggage transfer drivers,” Richard Cox, Delta’s senior vice president of airport customer service, told AirlineGeeks. “We make sure our customers can travel with peace of mind.”

Human-AI Collaboration on the Ramp

For veteran ramp agents like Mike Davis — an 11-year Delta employee and multiple-time Driver of the Month — the system has transformed the job. “I don’t have to focus on crunching numbers and trying to figure out my own route. It does all that for me,” Davis told NPR. “It tells me which gate. All I got to do is just to get there.”

Davis acknowledged the system isn’t perfect, sometimes assigning very tight connections. But he embraces the change: “You know how they say, ‘out with the old and in with the new?’ That’s what it is. It’s called continuous improvement. You have to change with the times to be relevant.”

Crucially, Delta emphasizes that AI will not displace human ramp employees. “We don’t see AI as something that is going to replace our people,” Buckley said. “We see AI as an enabler, an enabler of performance, and giving the tools to our people to go produce at an even better level.”

Broader Investment in Innovation

Baggage AI is part of a larger push by Delta to modernize ground operations. The airline has invested $110 million in infrastructure at ATL, including $40 million in 2025 to connect baggage systems across Concourses B, C, and T. Delta has also deployed autonomous jet bridges on Concourse B — the first in commercial aviation — which have supported more than 1,100 flights with zero incidents, and autonomous bag tugs that have logged 4,000 miles since 2023 without injury or damage.

Delta handled 127 million bags worldwide in 2025, with fewer than 1% mishandled, according to the company. Aerospace Global News noted that during peak periods like Thanksgiving, Delta carries over 380,000 bags daily, with more than 99% arriving on time.

What’s Next

Delta plans to expand Baggage AI to its hubs in Detroit (DTW) and Minneapolis-Saint Paul (MSP) later in 2026. Future enhancements include optimization for ramp congestion and weather-related delays, autonomous dispatching that eliminates empty drives across the airport, and bag scanning for transfer drivers to enable real-time adaptation when customers rebook mid-flight.

As the Memorial Day weekend kicks off the busiest travel season of the year, Delta’s Baggage AI represents a significant step forward in applying artificial intelligence to the complex, real-time logistics of aviation — ensuring that millions of bags arrive where they need to be, when they need to be there.
