The average delay of late vessels globally was nearly five days in September, according to data from Sea-Intelligence Maritime Analysis, reported IHS Media.
Global on-time performance in September was the lowest recorded this year, in which the best carriers could achieve was 77.7 per cent in June when huge amounts of capacity were blanked on the major trade lanes.
Transpacific was the worst, as a record surge in US imports from Asia clogged the southern California ports of Los Angeles-Long Beach and led to delays.
Sea-Intelligence data show Asia-US west coast trade reported on-time performance of 46.7 per cent in September, down from 62.2 per cent in August and a sharp decline from 86.7 per cent in June.
Carrier performance on the Asia-US east coast was little better, with the 49 per cent schedule reliability in September down 11.7 percentage points from August and 38 percentage points since June.
On-time performance on the Asia-North Europe trade declined 10.4 percentage points from August to 69 per cent in September, which is down from a 2020 high of 91.6 per cent in June.
