Sea-Intelligence has published issue 166 of the Global Liner Performance (GLP) report, with schedule reliability figures up to and including May 2025. As the 120-page report is quite comprehensive and covers schedule reliability across 34 different trade lanes and 60+ carriers, this press release will only cover highlights from the full report.

In May 2025, schedule reliability recorded a sharp 7.4 percentage point improvement M/M and reached 65.8%. This is the highest figure recorded since November 2023 and continues the trend of consistent M/M improvements since February this year. On a Y/Y level, schedule reliability was up 10.0 percentage points. Maersk was the most reliable top-13 carrier with schedule reliability of 75.9%, followed by Hapag-Lloyd with 72.5%. The next 6 carriers were in the 60%-70% range, and the remaining carriers were in the 55%-60% range. ONE had the lowest May 2025 schedule reliability of 55.1%.

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, we introduced a new measure, based on all arrivals, including the origin region calls on the East/West trades. We 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 April/May 2025, Gemini Cooperation recorded 90.9% schedule reliability across ALL arrivals, and 88.4% across TRADE arrivals, followed by MSC at 70.5% for ALL arrivals and 77.9% for TRADE arrivals, while Premier Alliance recorded 55.2% for ALL arrivals and 52.7% across TRADE Arrivals. For the “old” alliances, “ALL arrivals” are equal to “TRADE arrivals”, and Ocean Alliance scored 57.4%.

It is important to stress though, that the new alliances will only be fully rolled out in July 2025, and only then will it be possible to truly evaluate their performance.
