Airline give you an ETA (ESTIMATED time of arrival). It's not a guaranteed arrival, and there is nowhere you will see that they guarantee you will arrive at that time. As I asked earlier, would you take a road trip that is exactly 14 hours long without any traffic etc (perfect circumstances), and leave exactly 14 hours ahead of time, or would you plan ahead and give yourself extra time for unforseen circumstances?
As far as your comment about being compensated, the airlines do compensate people when they have to bump you, or of your flight gets delayed/cancelled.
they base their own scheduling on their own estimates
so it's pretty clear that the airlines reasonably assume that they're going to land when they say they will
since they are the ones with all of the data supporting their assumptions, why are we the idiots for relying on their say so?
