LD-6 FAQ

The LD-6 is a lower-deck container with the IATA code ALF, rated Type 6W. The same unit also appears under DLF, MLF, RLF, AWA, AWF, AWC, which are the prefixes different airlines assign to it.

Around 9.1 m³ of usable volume, up to 3,175 kg gross — the unit and its cargo together. The unit itself weighs 230 kg empty, so the payload is the difference between the two.

It is loaded on 747, 767, 777, 787, DC-10, MD-11, A300, A310, A330, A340, A380, IL86, IL96, L1011. 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.
