What does the SSR code AVIH indicate?

The SSR code AVIH stands for "Animal transported in the hold." This code is primarily used in the airline and travel industry to denote that a live animal is being shipped in the cargo area of the aircraft, rather than in the passenger cabin. This designation is crucial for ensuring that all necessary arrangements are made for the safe and appropriate handling of the animal during transport.

The AVIH code communicates specific requirements related to the animal's transport, such as temperature control and ventilation, which are vital for the animal's welfare. Furthermore, it allows airline staff to be prepared for the arrival and unloading of the animal upon reaching the destination.

Other options relate to special assistance needed for passengers but are not relevant to the context of transporting animals.
