Seconded. For example, there is no way to delete something once it is added into your itineraries. If your schedule changes frequently, as mine does, it becomes a mess. Today for example, I have 12 flights showing - yes, 12, plus 4 hotel bookings - because of how many changes I've made. And no way to delete the now irrelevant info. And the flight status updates are nowhere near timely enough to be useful.

AA iphone app? I dunno, doesn't matter really to me as the mobile site is pretty good.
