The phrase "queues up" is commonly used to refer to waiting in a line. However, there are several synonyms that can be used in its place to convey the same meaning. One such option is "lines up," which is especially common in North America. Another synonym is "waits in line." The phrase "forms a line" can also be used, although it describes the action of creating a line rather than waiting in one. Other options include "gets in line," "stands in line," and "queues." Ultimately, the choice of synonym will depend on context and personal preference.
