Istanbul vs. Atlanta: A Mega-Airport Comparison in the Era of Triple Parallel Runway Operations

As Istanbul Airport (IST) achieved a major milestone with the activation of triple parallel runway operations, it joined the ranks of only a few airports in the world with such advanced air traffic management capabilities. Among these elite hubs is Hartsfield-Jackson Atlanta International Airport (ATL)—consistently ranked as the busiest airport in the world.

This article explores how these two global aviation powerhouses compare in terms of passenger capacity, air traffic management, strategic importance, and operational infrastructure.

1. Airport Capacity and Infrastructure

Both airports are mega-hubs, but their core focus and capacity plans differ.

FeatureIstanbul Airport (IST)Atlanta Airport (ATL)
Design Capacity200 million passengers (future plan)~107 million passengers (2023 actual)
Current Passenger Volume~76 million (2023)~107 million (2023)
Aircraft Movements (2023)~500,000~724,000
Runways5 parallel5 parallel
Triple Parallel Ops✅ Enabled✅ Enabled

Both ATL and IST are capable of triple independent parallel runway operations, a critical feature that enables high-volume simultaneous landings and departures, significantly improving efficiency and throughput.

2. Strategic Location and Connectivity

Geography plays a huge role in each airport’s connectivity and influence.

FactorIstanbul Airport (IST)Atlanta Airport (ATL)
LocationCrossroads of Europe, Asia & AfricaSoutheastern U.S.
Transfer RoleMajor global connectorPrimarily domestic with international extensions
Time Zone AdvantageIdeal for East-West transfersEfficient for North & South America
Global FunctionIntercontinental transfer hubU.S. domestic and American region hub

IST excels as a global connector, especially for flights bridging Europe, Asia, and the Middle East. ATL, while less prominent for intercontinental transfers, is the backbone of domestic U.S. connectivity and a vital link to Latin America.

3. Air Traffic Management (ATM) Systems

The backbone of any airport’s efficiency is its ATM capabilities.
