From what I know I don’t have to make this a feature request but correct me if I am wrong.
Recently KSEA has been getting renovations of it’s N Terminal, adding a couple gates (which are already in service), and S terminal. It would be nice if the Airport Editing Team could push an update out to this airport sometime.
The Airport Editing Team is aware that airports are changing every time. Eventually, an editor would be interested and renovate it. We usually don’t take requests from the public as we edit the airports we want or that have some priority/value, but I’m sure we’ll someday get to redo KSEA.
