How accurate is this feature? Can I be reasonably certain that my flight will be delayed based on that feature, and that there is just a lag in the update to the flight status?
No. Do not trust it at all. Aircraft get swapped in and out of routes all day, every day. Such is the job of the resource managers. Be at the gate minimum 15 minutes prior to scheduled departure - earlier if possible.
