I wanted to ask if it’s permissible for a female to travel abroad without a male mahram accompanying her, for both leisure (holidays) or for more compulsory reasons such as work or visiting family.
For holiday reasons, if I have the permission of my parents and am going with females and do not intend to engage in anything sinful, is this permissible?

As you mention that there is no fear of sin then you are allowed to travel but again I request you to make sure that there is no fear of falling haram or sin
