In April, global schedule reliability improved by 1.7 percentage points M/M to 58.7%, the highest level recorded since November 2023, according to Danish maritime data analysis company Sea-Intelligence.
On a Y/Y level, the April score was higher by 6.5 percentage points.
Maersk was the most reliable top-13 carrier in April 2025 with a schedule reliability score of 73.4%, followed by its Gemini partner Hapag-Lloyd at 72.3% and MSC at 60.7%.
According to Sea-Intelligence’s methodology, alliance scores are based on arrivals in destination regions, but as that metric was not available for the new alliances in February, as the newly launched alliance services only had origin arrivals in February, the Danish analysts introduced a new measure for the new alliances, based on all arrivals, including the origin region calls on alliance services.
Both of these measures are shown in the following figure: “All arrivals” includes both origin and destination calls and is comparable to the February 2025 score, and “Trade arrivals”, which is comparable to the “old” alliances and only includes destination calls.
“When the new alliances are fully rolled out, these two measures will converge,” explain the analysts.
In March/April 2025, Gemini Cooperation recorded 90.7% schedule reliability across ALL arrivals, and 87% across TRADE arrivals, followed by MSC at 69.8% for ALL arrivals and 77.3% for TRADE arrivals, while Premier Alliance recorded 53% for ALL arrivals and 51.3% across TRADE Arrivals.
For the outgoing alliances, “ALL arrivals” are equal to “TRADE arrivals”, and Ocean Alliance scored 51.1%, while THE Alliance scored 49.8%, and 2M scored 33.5%.
“It is important to stress, though, that the new alliances will only be fully rolled out in July, and only then will it be possible to truly evaluate their performance,” noted Alan Murphy, CEO of Sea-Intelligence.
