What is the ruling regarding a lady who wants to perform Umrah but her mahram is not willing to accompany her ? Is she allowed to travel with an agency?

There are alot of ladies who travel from jeddah to makkah in bus without mahram and perform umrah. When i asked they said our mahram is in jeddah not very far from makkah so we can perform umrah without them. Is it permissible?
