LD-39 FAQ

The LD-39 is a lower-deck container with the IATA code AMU, rated Type 2BG. The same unit also appears under DMU, MMU, RMU, which are the prefixes different airlines assign to it.

Around 15.9–16.9 m³ of usable volume, up to 5,035–5,100 kg gross — the unit and its cargo together. The unit itself weighs 290 kg empty, so the payload is the difference between the two.

It is loaded on 747. A type is certified per aircraft and sometimes per door, so a unit that fits one freighter will not always fit another.

Track the shipment rather than the unit: the air waybill number is what the airline reports against. Enter it in the air tracking app, or make the same lookup one REST call with the API reference.
