Overall Schedule Reliability Performance

Global schedule reliability has stabilized between 65-68% since May 2025, which represents significant improvement compared to 2024. In August 2025 specifically, global schedule reliability reached 65.3%, marking the second-highest figure for the month across 2019-2025. Sea-Intelligence

Trans-Pacific Specific Performance

For the Asia-North America routes during peak season:

1. Asia to U.S. West Coast: Achieved 78% reliability in June 2025, showing a five-point improvement month-over-month C.H. Robinson
2. Asia to U.S. East Coast: Reached 71.2% reliability in June 2025 C.H. Robinson
3. Average delays for late vessels improved to approximately 4.5-5 days, which is the best performance in nearly two years

Carrier Performance Rankings

Among top carriers during this period:

1. Maersk led with 76.4% reliability (some reports show 75.9%)
2. Hapag-Lloyd followed with 72.5% reliability
3. Wan Hai posted the lowest among top carriers at 53.3% TFG Global

Peak Season Context

The 2025 peak season showed some unique characteristics:

1. Early Peak: The typical September surge occurred earlier this year, with peak volumes shifting to late summer
2. Golden Week Impact: China's Golden Week (October 1-8, 2025) was extended due to overlap with Mid-Autumn Festival, creating significant scheduling pressures
3. Blank Sailings: Carriers implemented aggressive capacity management, with approximately 544,000 TEU withdrawn across Trans-Pacific and Asia-Europe routes in September through blank sailings TFG Global

Additional Disruptions

1. Typhoon Ragasa shut down key South China terminals (Yantian, Shekou, Nansha, Hong Kong) between September 22-25, creating backlogs that affected reliability
2. Port congestion at major transshipment hubs continued to impact overall performance

Summary

The trans-pacific on-time performance for peak season 2025 showed significant year-over-year improvement, with reliability in the 65-78% range depending on the specific route. This represents a 12+ percentage point improvement compared to 2024, though it still falls short of pre-pandemic performance levels. The Asia-West Coast route performed best at 78%, while the industry managed to maintain this improved reliability despite typical peak season challenges and weather disruptions.
