This past weekend was my final trip as a DL elite (silver).
Two segments cleared the day ahead (SEA - CVG & CAE - ATL); one went to gate lottery (ATL - SEA) with GIDS opening @ 10 "unassigned" FC - I was #1 of 2 at that point (all three segs were U fares), clearing about 20 mins before boarding.
My only other paid DL flight under new system (Silver, last autumn) was SEA - SLC - SEA. Outbound failed, but the exit row was OK for a 90 min flight; return cleared GIDS @ 1 minute before FC boarding.
