What does the code PETC refer to in airline requests?

The code PETC refers to "Animal in Cabin," which is used by airlines when passengers request to have a pet accompany them in the cabin of the aircraft. This term is important in the context of airline operations as it indicates to the flight crew and ground staff that a passenger has a pet with them that needs to be accommodated according to the airline's policies and regulations regarding cabin animals.

Understanding this code is crucial for ensuring that all necessary arrangements are made prior to boarding, including seating considerations and any required pet documentation. Additionally, it allows for communication regarding the pet's needs, which can help the passenger have a more comfortable flight experience.
