AOG

Transportation & Travel abbreviation · Aviation

AOG stands for Aircraft on ground, an aviation abbreviation.

Highest-priority maintenance status meaning an aircraft is grounded by a technical problem and cannot fly until a part or repair arrives. AOG orders trigger round-the-clock shipping of parts, often by courier on the next available flight.

Example: We're AOG in Anchorage with a cracked windshield, and the replacement is flying in from Seattle tonight.

Usage notes

Parts suppliers and airlines run 24-hour AOG desks because an idle airliner loses revenue every hour, with widebody costs commonly estimated in the tens of thousands of dollars per day. Packages are labeled "AOG" for priority handling by freight forwarders and customs brokers.
