Aircraft on Ground: Contingency Plans for the Car
An unserviceable aircraft turns a transfer into a whole day of arrangements, usually at short notice.
What the term actually means
Aircraft on ground, shortened to AOG throughout the industry, describes an aircraft that cannot fly until a technical issue is resolved. It ranges from a component swap taking an hour to a fault that keeps the aircraft in a hangar for days. The passenger sees only the outcome: a departure that is not happening on time, and sometimes not happening at all from that airfield.
The shapes a delay can take
There are broadly three outcomes and they demand different responses. A short delay means waiting, comfortably, at the facility. A long delay means the party leaves and returns later, which needs a vehicle for the intervening period. A cancellation means new arrangements entirely: a hotel, a replacement aircraft from elsewhere, a scheduled flight, or a long road journey instead. The ground plan has to be able to become any of these.
- Short delay: hold at the facility, vehicle standing by
- Long delay: leave and return, with the car retained
- Cancellation: hotel, replacement aircraft or a road alternative
Keeping the car in the arrangement
The instinctive reaction to a technical delay is to release the vehicle and rebook later. Sometimes that is right; often it is not, because the second booking has to compete with whatever else is happening that day. Where a delay is likely to be measured in hours rather than the whole day, retaining the vehicle usually produces a better outcome, and how that time is treated is agreed at the point the decision is taken.
Road as the fallback
For domestic trips, a car can sometimes replace the flight entirely. A journey that was going to be a short hop north or west is a long but entirely achievable drive, and for a party with a fixed commitment it may be the answer. That decision needs taking early, because a drive that works if it starts at midday does not work if it starts at four, and the aircraft will not always give a clear answer by then.
Planning for it without dwelling on it
None of this needs an elaborate contingency document. It needs one conversation at the booking stage: who decides if the aircraft goes technical, how the car is treated while everyone waits, and whether a road alternative is realistic for this particular journey. Ten minutes of thought in advance is worth several hours of improvisation on the day.

Frequently asked questions
What does AOG mean?
Aircraft on ground: an aircraft that cannot fly until a technical issue is fixed. It covers everything from a short repair to a fault that keeps the aircraft out of service for days, and the passenger experiences it as a delayed or cancelled departure.
Should the car be released during a technical delay?
It depends on how long the delay is likely to be. For a few hours, retaining the vehicle is usually better than rebooking into a busy day. How the waiting period is treated is agreed at the moment the decision is taken rather than assumed.
Can we drive instead if the aircraft is unserviceable?
For domestic journeys, often yes, and for a party with a fixed commitment it may be the best option. The decision needs taking early, because a long drive that works starting at midday does not work starting in the late afternoon.
How do we plan for this in advance?
With one short conversation when the booking is made: who makes the call, how waiting time is handled and whether a road alternative is realistic for that route. That is usually enough to make an unexpected day manageable rather than chaotic.
