I’d be happy to help!
The phrase “八百多的自由飞成人票” is likely referring to the concept of “one-way tickets.”
So, in this context, you’re asking if a ticket that allows freedom flights for more than 800 people (八百多) can only have one person on it.
To answer your question: generally speaking, yes. A one-way ticket means there’s no return trip or round-trip option; the passenger embarks from one place and disembarks at another without coming back.
