Showing people information like this removes uncertainty and makes them feel more calm and in control, even if they can't necessarily act on the information immediately. It promotes the idea that the airport believes that user time is valuable, that the airport cares about performance, and that they are trying to optimize processes when possible and provide useful information. This contrasts strongly with the attitude that one normally associates with airports, which is that the entire travel process is insanely uncertain and no one working there gives a shit about you. This improves both passenger and staff morale (as staff are the obvious targets of undirected passenger anger and frustration) and makes the process feel more seamless.
