Korean Air completes Incheon 'Smart Terminal', lifting cargo capacity by 25%

Korean Air has finished modernising its cargo terminal at Incheon International Airport (ICN), a project that lifts the facility's handling capacity by more than 25% and pushes its throughput from 18 to 30 unit load devices (ULDs) per hour.

The work ran from June 2025 to September 2026, and the airline says cargo operations continued without disruption throughout the renovation — a point that matters commercially, because a live terminal upgrade that stops freight flow would cost an operator far more than the construction itself.

The 'Smart Terminal' label is Korean Air's own, and the substance behind it sits in two pieces of equipment: automated guided vehicles (AGVs) and new elevating transfer vehicles (ETVs), which move containers around the terminal with far less manual handling than before.

What actually changed on the floor?

The core of the project is mechanical, not decorative:

• AGVs and ETVs now shuttle cargo containers through the building, replacing much of the manual movement.
• The bypass system, which routes containers through the facility, has been expanded from a single line to two automated transfer lines linked to the new ETVs.
• That doubling of lines is what drives the jump from 18 to 30 ULDs per hour.
• Korean Air expects the terminal's overall cargo handling capacity to rise by more than 25% as a result.

ULDs are the standard containers and pallets used to carry air freight, so hourly ULD throughput is the most direct measure of a terminal's ability to absorb volume. A 67% increase in that figure — 18 to 30 units — suggests the headline 25% capacity gain is, if anything, a conservative framing constrained by other bottlenecks such as dock space and aircraft turnaround.

The airline is also expanding facilities for special cargo, a category that typically earns higher rates than general freight. That is where the margin sits: perishables, pharmaceuticals and other specialised shipments command premiums that plain palletised cargo does not.

The workforce angle

Korean Air frames the project as much as a labour measure as a capacity one. Automating heavy equipment reduces how often workers handle cargo manually, and the airline says other infrastructure upgrades improved the overall work environment at the terminal.

A Korean Air representative said the renovation was an essential step in responding to rapid changes in global logistics by upgrading equipment and adopting smart technologies.

That rationale tracks with what ground handlers across the industry face: cargo handling is physically demanding work with high turnover, and automation offers a way to sustain throughput without a constantly replenished labour pool.

What comes next

With Incheon complete, Korean Air has already moved on. The airline is now modernising its cargo terminal at John F. Kennedy International Airport (JFK) in New York, with completion planned for 2027.

The JFK project gives Korean Air a second data point on whether the Incheon formula — AGVs, twin ETV lines, expanded special-cargo space — can be replicated at an overseas hub rather than just proven at home. If the 2027 delivery matches the Incheon result, the carrier will have a repeatable template for terminal automation across its network.
