Transit Time (T/T)
Transit Time (T/T) is the elapsed time a shipment takes to move from origin to destination. It is quoted either port-to-port (the ocean or air leg only) or door-to-door (including pickup, customs and final delivery). Transit time is one of the most important service commitments a forwarder or carrier makes, directly affecting inventory planning and customer satisfaction.
Ocean transit times depend on the trade lane, the service string and the number of transshipments; air transit is faster but costlier. Accurate, real-time transit-time prediction — factoring in port congestion, rollovers and weather — is a core capability of AI-driven logistics platforms, which compare promised versus actual T/T to flag at-risk shipments early.
Transit time is one of the core promises a carrier makes, and it drives inventory and customer planning. The catch is what is included — a port-to-port quote hides pickup, customs and delivery — so predicting the real, door-to-door T/T, and flagging when it is slipping, is where AI adds value.
What is the difference between port-to-port and door-to-door transit time?
Port-to-port covers only the ocean or air leg; door-to-door adds pickup, export and import customs and final delivery — so the door-to-door figure is always longer and more useful for planning.
What affects ocean transit time?
The trade lane and service string, the number of transshipments, port congestion, rollovers and weather. AI-driven prediction factors these to forecast real arrival and flag at-risk shipments.
