MAWB (Master Air Waybill)
The master transport document for air cargo: an 11-digit IATA number — 3-digit airline prefix + 7-digit serial + 1 check digit (serial mod 7). The prefix identifies the airline; TrackJet resolves it against its own carrier directory. A House AWB (HAWB) is the forwarder-issued counterpart and follows the forwarder's own numbering.
