Shippingtelegraph: Container line schedule reliability saw first drop since January

Denmark-based research and analysis specialist Sea‑Intelligence reported that global schedule reliability saw the first drop in July since January 2025.

Sea-Intelligence released its 168 issue of the Global Liner Performance (GLP) report, with schedule reliability figures up to and including July 2025.

“In July 2025, schedule reliability declined M/M for the first time since January 2025, dropping by -2.2 percentage points M/M to 65.2%,” said Alan Murphy, chief executive officer of Sea-Intelligence.

On a Y/Y level, schedule reliability in July 2025 was up by 13.0 percentage points. The average delay for late vessel arrivals deteriorated, increasing by 0.14 days M/M to 4.68 days.

Maersk has climbed in the first place as the most reliable top-13 carrier in the report with schedule reliability of 80.6%, followed by Hapag-Lloyd with 74.0%.

The next 6 carriers were in the 60%-70% range, and the remaining carriers were in the 50%-60% range.

Traditionally, alliance scores are based on just the arrivals in destination regions, but as that metric was not available for the new alliances in February, Sea-Intelligence introduced a new measure, based on all arrivals, including the origin region calls on the East/West trades.

Sea-Intelligence continues to present both measures, “All arrivals” which is comparable to the February measure, and “Trade arrivals”, which is comparable to the “old” alliances. When the new alliances are fully rolled out, these two measures will converge.

According to the report, in June/July 2025 Gemini Cooperation recorded 92.0% schedule reliability across ALL arrivals, and 89.6% across TRADE arrivals, followed by MSC at 76.5% for ALL arrivals and 76.2% for TRADE arrivals, while Premier Alliance recorded 54.6% for ALL arrivals and 54.8% across TRADE Arrivals. For the “old” alliances, “ALL arrivals” are equal to “TRADE arrivals”, and Ocean Alliance scored 69.4%.
