Estimated time of arrival, or ETA, is the forecast date and time when a vessel, aircraft, vehicle or shipment is expected to reach a specified location. It is an estimate that can change as conditions change.
What location does ETA refer to?
It may refer to a port, airport, terminal, warehouse or customer site. The location and time zone should be stated.
How is ETA produced?
Carriers and tracking systems use schedules, current position, route, speed, congestion, weather and operational events to update the forecast.
ETA versus delivery date
Arrival at a port or terminal does not mean cargo is cleared or delivered. Customs, discharge, availability, pickup and final transport can add time.
How should ETA changes be managed?
Keep the original plan, current forecast, source and update timestamp. Notify affected inventory, production or customer teams when the change crosses a defined threshold.
What other milestones matter?
Review estimated departure, actual departure, actual arrival, cargo availability, customs release and proof of delivery rather than relying on ETA alone.
