Airport staff don't maintain infrastructure, at best they maintain front ends to it

You consider signage infra? Same with conference rooms. Most of the places I have worked have facilities type people working on it. Tier 3 is usually a direct phone call away for them

You would send an engineer into an airport to reboot a sign?

Of course not. Thats the point I was making

At some airports, staff does maintain infrastructure.

At others, airline staff is responsible for it. And just like airport staff, a tech who can deal with Firefox on Windows is cheaper than someone who can troubleshoot the same in Linux or a more custom system.
