M-6 Twin Car Rack FAQ

The M-6 Twin Car Rack is a main-deck pallet with the IATA code PRA, rated Type 1P. The same unit also appears under PMA, P4A, P4M, PZA, which are the prefixes different airlines assign to it.

Up to 8,900 kg gross — the unit and its cargo together.

It is loaded on 747F, 747 Combi, 777F (center loading only). 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.
