search – What’s the use case for ‘flight schedule’ on airline website and apps

I’m working on redesigning the existing flight schedules feature on an airline mobile app. but I realize in terms of functionality, is very similar to the flight search but with lesser options. So in some sense these are competing features on the same platform.

I’m curious if anyone knows what’s the use case for ‘flight schedule’ on airline websites and apps. how are they different from flight search.enter image description here
