What does POB refer to in airline terminology?

In airline terminology, POB stands for "Passenger On Board." This term is commonly used by flight crews to indicate the total number of passengers currently on the aircraft. Knowing the POB is essential for various operational reasons, including safety, weight and balance calculations, and in-flight management. It also plays a key role in emergency procedures, as accurate counts are necessary for ensuring all passengers are accounted for in case of an evacuation or other emergency situations. Thus, when discussing passenger load and logistics, it is vital for crew members to communicate and confirm the POB accurately.
