# Schedule Reliability for Sea Freight

*Last updated: 2026-06-18*

> Freight forwarders, shippers, and procurement teams rely on schedule reliability to assess how consistently liner carriers adhere to their published port-to-port timetables.

Freight forwarders, shippers, and procurement teams rely on schedule reliability to assess how consistently liner carriers adhere to their published port-to-port timetables. It is expressed as the percentage of sailings arriving or departing within a defined tolerance – commonly 24 hours – of the scheduled time. Poor reliability has immediate operational consequences: demurrage and detention charges accumulate, customs filings require revision, and downstream production or distribution plans are disrupted. Root causes include adverse weather, port congestion, Suez or Panama Canal restrictions, and vessel mechanical failures. Data providers such as Sea-Intelligence publish regular carrier rankings, giving forwarders a factual basis for service selection.
