Global industry schedule reliability fell month-on-month by 3.5 percentage points to 61.4% in October 2025, according to a press release from Sea-Intelligence.
The decline marked only the second significant M/M drop in 2025 and followed three months of stable performance.
Year-on-year, schedule reliability increased by 11.1 percentage points.
The average delay for late vessel arrivals edged up M/M by 0.04 days to 4.98 days, while remaining 0.87 days lower Y/Y.
Maersk was the most reliable top-13 carrier in October 2025 with 74.1%, followed by Hapag-Lloyd at 69.6% and MSC at 65.9%.
Nine of the remaining ten carriers were in the 50–60% range, and PIL ranked lowest at 44.9%. Sea-Intelligence noted that it continues to use two alliance metrics: “All arrivals,” introduced in February when data for destination-only arrivals was unavailable for new alliances, and “Trade arrivals,” aligned with the earlier methodology.
The two measures are expected to converge once the new alliances are fully implemented.
In /October 2025, Gemini Cooperation recorded 88.6% schedule reliability across All arrivals and 86.0% across Trade arrivals. MSC followed with 77.5% for All arrivals and 80.5% for Trade arrivals.
Premier Alliance reported 64.6% for All arrivals and 54.6% for Trade arrivals. For the “old” alliances, where both metrics coincide, Ocean Alliance posted 65.0%.
