Jeju Air (7C) August 2025 Operational Report

Flight Activity Overview

Total arriving flights: 6,765

Year-over-year change: +1.33%

Jeju Air saw solid summer demand into Korea’s leisure markets, with Jeju and Seoul remaining the strongest arrival flows. The year-over-year change reflects a fuller restoration of regional travel and a careful matching of capacity to holiday peaks, especially on domestic trunk routes. Competition from full-service and low-cost rivals kept fares disciplined, but the airline leveraged higher aircraft utilization and dense morning-evening wave banks to protect connectivity.

On-Time Performance and Cancellations

On-time arrival rate: 91.16%

Change vs last year (on-time rate): +4.01 percentage points

Cancelled flights: 9

Year-over-year change (cancellations): -70.00%

Punctuality was shaped by seasonal weather over the Korean peninsula, air traffic flow management at busy Seoul terminals, and ground turnaround efficiency at Jeju. In response, Jeju Air tightened maintenance intervals before peak rotations, added reserve crews and spare aircraft windows on storm‑prone days, and refined gate/stand assignments to shorten taxi and block times. These measures helped stabilize schedule integrity even when localized thunderstorms and typhoon bands disrupted parts of the network.

Key Hubs

The backbone of the network runs through Seoul Incheon and Jeju, supported by Seoul Gimpo and Busan for domestic density. Incheon concentrates international leisure flows to Japan and Southeast Asia, while Jeju anchors island tourism and short‑haul connectivity to the mainland. Wave scheduling at morning and late evening facilitates tight connections despite curfews and peak apron congestion.

Outlook

For travelers, Jeju Air offers reliable coverage of peak holiday flows with clear strengths on Jeju and Seoul routes. Expect punctuality to remain broadly stable as storm‑season buffers and crew reserves stay in place, with small gains targeted through ground‑process automation. Looking ahead to the autumn shoulder, the carrier plans tactical capacity trims on softer days and selective frequency additions to Japan and Southeast Asia to protect connections and improve customer choice.
