Global container schedule reliability slipped to 62.8% in December 2025, down 1.2 percentage points month on month and marking one of the weakest readings since May, according to the latest Global Liner Performance report from Sea‑Intelligence.

Average delays for late vessel arrivals also inched higher to 5.04 days, even as both metrics remained improved compared with a year earlier.

Sea-Intelligence said Maersk was the most reliable top-13 carrier in December 2025 with schedule reliability of 76.7%, followed by Hapag-Lloyd with 75.2%.

Meanwhile, only four carriers recorded a M/M improvement, while all 13 carriers recorded a Y/Y improvement in schedule reliability.

In November/December 2025, Gemini Cooperation recorded 92.3% schedule reliability across ALL arrivals and 90.8% across TRADE arrivals, followed by MSC at 73.5% for ALL arrivals and 71.9% for TRADE arrivals.

Premier Alliance recorded 56.9% for ALL arrivals and 56.6% across TRADE arrivals. For the "old" alliances, "ALL arrivals" remain equal to "TRADE arrivals," and Ocean Alliance scored 58.8%.

"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," said Alan Murphy, CEO, Sea-Intelligence.

"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," he added.
