Trans-Pacific on-time performance sinks to 26.9% as booking risk climbs

Only 26.9% of Asia–North America shipments arrived on time in September, down 7 percentage points from 33.9% in August, and WiseTech Global expects vessel capacity on the lane to tighten further as carriers withdraw sailings into late October.

The four-week Ocean Freight Risk Outlook, published by the logistics software provider, combines forecast demand, planned carrier supply, booking responses, arrival performance and port conditions. Its message for shippers is blunt: on the trans-Pacific, securing space is about to get harder, and deliveries are already late.

"Capacity is forecast to tighten towards the end of the outlook period, driven by reduced planned carrier capacity rather than stronger demand," WiseTech said of the Asia–North America trade. That distinction matters. This is a supply-side squeeze engineered by carriers, not a demand surge — a caveat shippers should weigh before assuming rates signal underlying trade strength.

The booking security risk indicator for the lane is expected to rise and stay well above its historical average, meaning greater difficulty obtaining space on preferred sailings. The latest weekly on-time reading, 26.8%, barely improved on September's monthly figure, and delays of eight days or more remained the largest arrival-outcome category.

What is driving the trans-Pacific deterioration?

WiseTech attributed September's waterside pressure to continuing disruption at Asian ports, with vessel delays effectively cutting trans-Pacific capacity. China's Golden Week holiday adds a further wrinkle: because the holiday disrupts production and cargo flows, a post-holiday easing in demand may not immediately translate into better booking availability or schedule reliability.

Scheduled transit times look deceptively healthy. Published Asia–North America transits range from 26.2 to 27.6 days across the outlook period, below the recent 28-day baseline. WiseTech cautioned that weak actual performance continues to create uncertainty around arrival dates despite those schedules — the paper promise and the port reality diverge.

The company advised forwarders and beneficial cargo owners to book early against contracted allocations, pad delivery commitments with extra time, and weigh each carrier's individual reliability. Its analysis found substantial differences in service performance and booking acceptance risk among the trade's top 10 carriers — though the report does not name them, which limits how far shippers can act on that finding without their own data.

How bad is Asia–Europe reliability?

Worse, in raw terms. September on-time performance on Asia–Europe fell to 9.9% from 22.9% in August — the sharpest monthly deterioration of the three east-west trades. The latest weekly figure recovered modestly to 11.5%, but 45.5% of that week's volume arrived eight days or more late.

Capacity, however, is not the problem there. Planned carrier supply remains above projected demand, and booking security risk sits well below its historical average. Some tightening is expected late in the period as carriers trim planned capacity — again a carrier decision, not a demand signal. Delivery execution, not vessel space, is the principal risk.

"Shorter published schedules do not indicate improved service reliability, with recent arrival performance continuing to show substantial delays," WiseTech said. Planned Asia–Europe transits of 37.8 to 39.9 days sit below the recent 40.7-day baseline.

The report pointed to Asian port congestion and the ongoing split between Suez Canal–Red Sea routings and diversions around Africa as likely contributors to network disruption. Even the stronger-performing carriers show weak recent on-time results, limiting how much protection carrier selection alone can offer.

Is the trans-Atlantic any better?

Relatively, yes. Europe–North America shows planned supply exceeding forecast demand throughout the period, with booking security risk generally easing below its historical average. Conditions improve initially on increased planned capacity and softer demand, then tighten modestly as planned capacity declines later in the outlook.

Reliability still slipped: monthly on-time performance fell to 39.2% in September from 42.8% in August, before recovering to 38.6% in the latest weekly reading — where on-time arrivals remain the largest outcome category.

Carrier choice matters most on this lane. September on-time performance ranged from roughly 14% to 61% among carriers — a spread wide enough that route selection is a genuine operational lever, not a marginal optimization. Scheduled transits hold near the recent 19.1-day baseline, ranging from 17.7 to 19.5 days.

The through-line across all three trades: capacity numbers alone no longer tell shippers what to expect. With carriers managing supply downward and reliability deteriorating even where space is plentiful, forwarders and BCOs should treat published schedules with skepticism and build buffer into commitments until weekly on-time readings stabilize.
