Sea-Intelligence has published issue 179 of the Global Liner Performance (GLP) report, with schedule reliability figures up to and including June 2026.

Schedule reliability dropped M/M in June 2026 by ‑1.9 percentage points to 62.6%, which is still the second‑highest reliability figure for the year. On a Y/Y level, schedule reliability was lower by ‑4.7 percentage points. Despite declining schedule reliability, the average delay for LATE vessel arrivals improved, decreasing M/M by ‑0.34 days to 5.31 days, although it is still the third-highest figure for this month.
