I wonder if UA has a process to fix broken FIDS quickly. Does it help if we report problems to the gate agents?
Last Sunday in SFO, I passed by a set of them after 8 PM, yet the time on the FIDS are about 2 PM (frozen). It makes me wonder how in a busy hub, this kind of thing can be left unreported/unfixed for extended period of time.
I was looking at another set down the concourse and the arrivals screen was not refreshing properly.
I have also observed FIDS a few months ago at IAD that are displayed all different directions (side ways, etc.).
How they can be left broken and unfixed in hub airports really makes me wonder. Do they test them thoroughly? Do they monitor them to make sure they work? Do they have a process of fixing them quickly?
