A House Air Waybill (HAWB) is issued by the freight forwarder to the individual shipper and uses the forwarder's own numbering system.

Tracking status for a 525 AWB may not appear immediately after booking. It becomes visible only after the cargo has been physically accepted at a UNI AIR cargo terminal and the AWB has been activated in their system. This typically takes 2–8 hours after acceptance. If your AWB still shows no status after 12 hours, contact UNI AIR cargo customer service or your freight forwarder directly.
