San Diego airport is a joy to look out the window and convenient only if you arrange for someone to pick you up. Off airport rental cars are an extreme time sink and on-airport (Hertz Avis National) not much better. Why someone would design an airport such that you have to go down the stairs to get your bags on arrival go back up the stairs and then back down the stairs to cross over to parking or shuttles is beyond me. Lindberg Field was great until redesigned. If the airport wishes international traffic I am not sure why downtown in the current spagetti configuration makes no sense. Current proposals include a tunnel to a remote runway across the bay! Why not just build a proper airport and keep Linberg local. A long runway invites noise and a hub temptation that will hopefully die with Delta and United.
