Sea-Intelligence has published issue 177 of the Global Liner Performance (GLP) report, with schedule reliability figures up to and including April 2026. 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 April 2026, global industry schedule reliability increased by 0.4 percentage points M/M to 62.4%, making this the highest figure for 2026 so far. On a Y/Y level, schedule reliability was higher by 4.0 percentage points. With improving schedule reliability, the average delay for LATE vessel arrivals also improved, decreasing M/M by -0.27 days to 5.34 days. Despite this, on a Y/Y level, the April 2026 figure was 0.31 days higher.

Maersk was the most reliable top-13 carrier in April 2026 with schedule reliability of 76.1%, followed by Hapag-Lloyd with 75.1%. Five carriers each were in the 60-70% and 50-60% ranges, while Wan Hai was the least reliable carrier in April 2026 with schedule reliability of 39.6%. Five carriers recorded an M/M improvement in schedule reliability in April 2026, while 11 of the 13 carriers recorded a Y/Y improvement.

In March/April 2026, Gemini Cooperation recorded 85.0% schedule reliability across ALL arrivals and 85.6% across TRADE arrivals, followed by MSC at 73.4% for ALL arrivals and 72.3% for TRADE arrivals. Premier Alliance recorded 54.2% for ALL arrivals and 54.2% across TRADE arrivals as well. For the "old" alliances, "ALL arrivals" remain equal to "TRADE arrivals," and Ocean Alliance scored 67.6%.

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 2025, 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.
