How Does Zartico Distinguish Inbound and Outbound Passengers?

Device Observations

Devices are observed in the AIRSIDES of the partner airport, extending out to where the planes park at the gates. Airside areas provide the cleanest observation data of actual passengers, and will not have drop-off drivers, pickup drivers, family members, or other greeters. In addition, employees are filtered from these observations. 

An Airport’s Long-Term and Economy Parking areas, as well are Rental Car areas, are observed separately and have their own insights. 

Inbound vs. Outbound

When a device is observed in the Airport’s Airsides, we calculate the distance between that device observation and the “Common Evening Location” of that device—where the device lives. If the distance is LESS than 150 miles, the device observation is declared “Outbound” and is included in the Catchment insights in the ZDOS. If the distance is MORE than 150 miles, the device observation is declared “Inbound” and is included in the Origin insights in the ZDOS.

Outbound = Devices (i.e. passengers) who live within 150 miles of the airport, parking or POI. 

Inbound = Devices (i.e. passengers) who live more than 150 miles from the airport, parking, or POI. 

Duplicate Observations on the Same Day

If a device is observed several times in one day in the airport, we discard the extra observations and count them as one observation.


Zartico’s observations are then SUMMARIZED by month. There will be one accumulated count of devices seen in your airport within a month from one city. For example, it will show something like 500 devices from Lakeland, FL seen in the Tampa airport in January, 600 in February, 550 in March, etc.

You will not be able to see Catchment or Origin insights by week, or by day.
