In logistics and shipping, understanding the nuances between different Estimated Time of Arrival (ETA) metrics is crucial for effective planning and communication. Two key ETA types—ETA First Ever and ETA Confirmed—serve distinct purposes in tracking
ETA First Ever
The ETA First Ever represents the initial estimated time of arrival provided at the time of booking a shipment. This estimate is essentially a preliminary forecast based on available data when the shipment is first scheduled. It reflects a more commercial perspective and does not necessarily account for real-time developments or changes in the shipment's status.
For instance, if a vessel has already departed, the ETA First Ever might differ significantly from the booking date’s ETA. This is because the initial estimate is based on the planned schedule, which can be altered by various factors such as delays or route changes that occur after the booking.
ETA Confirmed
Conversely, the ETA Confirmed is the updated time of arrival communicated after the vessel has departed. This ETA is based on real-time data and reflects the most accurate arrival time based on the vessel's actual progress. It is the default estimate provided to clients once the vessel is en route, offering a more reliable forecast of when the shipment will arrive at its destination.
The ETA Confirmed is typically communicated once the vessel has departed and is thus based on the current operational status. This estimate is crucial for clients as it provides a realistic timeframe for when they can expect their shipment.
Key Differences

|
Timing of Update |
Given at the booking stage, this is an initial estimate subject to change. |
Provided after the vessel's departure, reflecting real-time conditions and delays. |
|
Accuracy |
Less accurate as it is based on preliminary data and may not account for post-departure changes. |
More precise as it takes into account the actual departure and any real-time delays. |
|
Implications of Delays |
Remains unchanged even if the vessel is delayed. It is the first estimate given, regardless of subsequent changes. |
Will be updated if there are delays or changes after departure. It provides the most current estimate of the arrival time. |
|
Availability |
Available from the point of booking. |
Only available once the vessel has departed and real-time data is accessible. |
In summary, while ETA First Ever provides an initial, often optimistic estimate, ETA Confirmed offers a more accurate and up-to-date arrival time post-departure. Understanding these differences is essential for effective shipment planning and managing expectations with clients.
Scenarios & Precautions
If a trade flow reference is received after the shipment has already departed, the "ETA First Ever" will not align with the ETA provided at the time of booking. This discrepancy arises because we only access the ETA when the shipment file is created. Therefore, the "ETA First Ever" merely reflects the first estimate received after departure. However, if references are added to Dockflow early in the process, it may accurately represent the ETA at the time of booking.
It's important to note that the ETA Confirmed will not be adjusted for any delays that occur after the vessel has left. This estimate reflects the closest available ETA at the time of departure.
When a vessel has just departed, it typically has an ETA; however, any delays that arise post-departure are not considered in the Confirmed ETA. For the most current and precise arrival prediction, users should refer to the "ETA (latest)."
