Sea-Intelligence has published issue 170 of the Global Liner Performance (GLP) report, with schedule reliability figures up to and including September 2025.
In September 2025, global industry schedule reliability recorded a marginal M/M improvement of 0.1 percentage points to 65.2%, the second-highest figure for the month (across 2019-2025). On a Y/Y level, schedule reliability in September 2025 was up 14.7 percentage points. The average delay for late vessel arrivals was unchanged M/M at 4.88 days.
Maersk was the most reliable top-13 carrier with schedule reliability of 77.0%, followed by Hapag-Lloyd with 73.6%. There were five carriers each in the 60-70% and 50-60% range. Wan Hai was the only carrier under the 50% mark and had the lowest September 2025 reliability of 47.9%.
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. They continue 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.
In August/September 2025, Gemini Cooperation recorded 89.1% schedule reliability across ALL arrivals, and 86.4% across TRADE arrivals, followed by MSC at 79.9% for ALL arrivals and 84.1% for TRADE arrivals, while Premier Alliance recorded 58.2% for ALL arrivals and 59.9% across TRADE Arrivals. For the “old” alliances, “ALL arrivals” are equal to “TRADE arrivals”, and Ocean Alliance scored 68.6%.
