I know that there are a lot of this kind of question but I've looked through as many as I can find and none fit my recollection of this story.

- There's a world where humans are able to teleport long distances, by visiting a central hub, like an airport, to do so.
- There's some talk about how occasionally people just don't show up the other end, but statistically it's still safer than air travel etc.
- Over the course of the story, the main character "goes missing" and it turns out that the teleport streams are being hijacked to build a secret resistance to something. 

My memory gets fuzzy there but I'd really like to re-read it.

As I recall, it was likely in an anthology that my parents had. They had a lot of old school anthologies. Ones that I remember were edited by James White and Isaac Asimov, I believe.
