Just noticed large changes in this year's schedules. Have one of my itineraries from PDX-ATL that doesn't even pull up the right flight number for the rescheduled itinerary (flight that didn't previously/doesn't exist). Used to have status with Delta but moved to American couple of years ago. Regretting it right now with generic non-elite wait times of 6hr for call and 1.5 hour for chat. Last nights east coast winter blast probably isn't helping.
