Tracking status for a 921 AWB may not appear immediately after booking. It becomes visible only after the cargo has been physically accepted at a SF 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 SF Airlines cargo customer service or your freight forwarder directly.
