I'm just trying to make sense of the information displayed in the arrivals hall (and on the airport website) when I'm picking somebody up. I feel like it always takes way longer than expected for people to show up after the flight status gets set to "Landed" (I haven't really seen any airport that differentiates between "Landed" and "Arrived").

In one recent case, people started showing up about 30 minutes after the flight status was set to "Landed". My friend whom I was picking up claimed they actually touched ground "5-10 minutes ago".
