What term is used for passengers who have arrived at an aerial port but have not reached their final destination?

The correct term for passengers who have arrived at an aerial port but have not yet reached their final destination is "in-transit passengers." This designation refers to individuals who may have scheduled connections or stops that are part of their overall journey and are waiting for their next leg of travel before completing their flight itinerary.

In-transit passengers often remain within the airport's international transit area and may not go through customs or immigration until they reach their final destination. It’s important to note that this term highlights their temporary status at the airport as they continue toward their end goal.

Other options, while related to air travel, do not accurately encapsulate the situation described. For instance, "transfer passengers" typically refers to those who change flights at the airport but may occasionally imply that they have more significant layovers. "Connecting passengers" also suggests travelers who must change planes, but it doesn’t specifically address their state of having arrived yet not reached their ultimate destination. "Layover passengers" usually refers to those who intentionally stop at an airport for an extended period, often implying a break in their journey rather than simply awaiting a connecting flight. Thus, "in-transit passengers" remains the best description for the scenario given in the question.
