Transit passenger is a term used to describe a person who is passing through a location on their way to a final destination. However, there are several other terms that can be used to describe transit passengers. For instance, the phrase "transit traveler" is another way to refer to someone who is passing through. Alternatively, one could use the term "transit visitor" to describe someone who is in a particular location for only a short period of time. Additionally, the term "layover passenger" could be used to describe someone who is waiting for their connecting flight or mode of transport. Whatever the case, there are plenty of synonyms and alternate terms that can be used to describe someone in transit.
