Understand historical performance of ocean legs to help you plan ahead. Available for ocean legs of international shipments, you can now find average historical sailing times for a given carrier.
Included in this new insight:
Average sailing time - this is represented by the dashed line going across the chart
The total sailing times of the most recent sailings - this is represented by the points shown in the chart
Hovering over individual points on the chart will give you the departure date of a given sailing and its total sailing time.
What is a sailing?
A sailing is an individual trip between two ports completed by a vessel. There can be multiple sailings started on the same day if the sailings are completed by different vessels.
How is travel/sailing time calculated?
The total travel time, or sailing time, for an individual sailing is calculated by taking the difference between the actual time of arrival (ATA) and actual time of departure (ATD).
How is average sailing time calculated?
To calculate the historical average sailing time we first look at all the sailings in your data for a given carrier between the two ports of interest. In order to calculate the average, we look at the 5 most recent sailings and only consider a sailing if it arrived in the last 12 months from the leg's date of arrival. The average is rounded to the nearest day.
To give you the most up-to-date average sailing time, we calculate the average once an ocean leg starts its move. This means we wait to see an ATD for the leg before we calculate the average.
If a leg is still in progress, we'll continue to look for recent sailings until the leg's ATA date. This means you may see the average change if a new sailing is taken into consideration.
I'm not seeing the average sailing time. Is something wrong?
In order to calculate the average sailing time there need to be at least 5 sailings between the specified ports completed by the same carrier in the previous 12 months. If you are not seeing the historical average sailing time insight it is likely that there were not enough sailings in your data for us to calculate the average
The average changed since I last looked at this shipment. Why is that?
When viewing an in-transit leg we'll look for matching sailings which have completed (have an ATA) on or before the current date. If additional qualifying sailings complete before the leg arrives, we're recalculate the average to give you the most up-to-date average. We'll continue to look for recent sailings until the leg's ATA date. This means you may see the average change if a new sailing is taken into consideration.
