Hartsfield-Jackson International Airport, which started as a humble airfield on an abandoned racetrack, set a world record Sunday by handling 100 million passengers in a single year.
The milestone capped a surprising 5 percent increase in passenger traffic this year.
"It's our commitment that we maintain our position as the world's most traveled airport," Atlanta Mayor Kasim Reed said in a ceremony before the flight arrived Sunday morning.
The official 100 millionth passenger: Larry Kendrick, of Biloxi, Miss. He stepped off his flight wearing blue jeans, an orange t-shirt, a ball cap and a bemused expression as he was greeted by dark-suited dignitaries, airport and airline workers and even the drumline from Tri-Cities High School.
Kendrick was selected based on accountants’ estimates of when the record-setting passenger would arrive.
“That’s a very big surprise,” said Kendrick, who got prizes including a new car and two Delta round-trip tickets.
“I have no clue where I’m going to go. Probably to Disneyland,” he said.
As commonplace as eye-popping numbers at Hartsfield-Jackson seem today, Sunday’s milestone remains a remarkable feat for an airport in a city many times smaller than others around the globe like New York, Mexico City and Tokyo.
One factor was the foresight of city officials in establishing and marketing Atlanta as an air hub. Another was the rise of the hub-and-spoke system that funnels passengers in and out of Hartsfield-Jackson.
About two-thirds of passengers in Atlanta are connecting, most of them on Delta Air Lines, which made Atlanta its home base in the 1940s and has since grown into a global power. It has a gigantic hub operation at Hartsfield-Jackson, which is owned by the city of Atlanta.
“It’s not because Atlanta has wonderful concessions or a brand new terminal,” Colorado-based airline consultant Mike Boyd said of Hartsfield-Jackson’s statistical prowess. “It’s decisions made by Delta Air Lines, period. That’s what’s done it.”
Delta is by far Hartsfield-Jackson’s biggest tenant, though a string of other carriers have had large operations contributing to its rise. They range from Eastern Airlines and Southern Airways to ValuJet, AirTran Airways and now Southwest Airlines.
Another factor that boosts traffic at Hartsfield-Jackson is the fact it’s the only commercial airport in the region. Bigger cities like Chicago and New York have second hub airports.
Various efforts over the years to create a “second airport” here have gone nowhere so far, though Paulding County’s small airport is currently trying to gain commercial certification and attract limited service. Both Delta and the city of Atlanta now oppose the idea, saying it would divert resources from improvements to Hartsfield-Jackson.
The airport has a $6 billion master plan to renovate the domestic terminal and concourses, demolish and rebuild the parking garages and eventually expand with more concourses and a sixth runway.
At one time passenger projections showed Hartsfield-Jackson with more than 120 million annual passengers by now. Various factors including the Great Recession slowed the growth rate, but it has picked up again and the 100 million milestone came faster than expected, airport officials said.
The title of world’s busiest could be at risk in coming years, however. Chicago O’Hare already regained the title for the most takeoffs and landings for 2014, though Atlanta still has the most passengers.
Many expect China’s Beijing International to soon surpass Atlanta as the world’s busiest airport, and Dubai’s airport is expanding to be able to accommodate as many as 240 million passengers a year.
Boyd said Atlanta — whose status as a Southeast economic superpower is largely credited to the airport — could even face increased rivalry from Charlotte, where American Airlines plans to grow its hub in the wake of a merger with US Airways.
“There’s going to be a lot more competition,” Boyd said.
