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

What if my 521 AWB shows no tracking status? +

Tracking status for a 521 AWB may not appear immediately after booking. It becomes visible only after the cargo has been physically accepted at a Airhub Airlines 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 Airhub Airlines cargo customer service or your freight forwarder directly.
