SWR should be clear on who they want to cater -- passengers or airport employees.
If it is just airport employees, then trains should be run according to their shift timings and so should not publicise that train conneiis there for passengers.
If it is meant for passengers, then SWR should run hourly trains from SBC to Airport (via YPR YNK) on hourly basis round the clock with a dedicated platform. Also Whitefield to airport (Via KJM YNK) on hourly basis round the clock.
