In the past, the bulkhead C+ seats of many narrow body aircraft were blocked but could be selected at exactly 24 hours prior to departure. This past week I have noticed that is no longer the case. The seats are still blocked (unassigned but not selectable) but they do not release at 24 hours. Anyone else noticing the same? Specifically 5CD on the CRJ-900 and 4DE of the A319/320.
I've noticed the opposite for a few bookings lately, and just assumed it was a glitch or something. For example, 21ABC on the 75U. usually blocked off, but were the blue C+ seats on the seat map when I clicked through.
