Yeah, it's a strange one. I'm not sure why they're waiting till last minute to change them. Its similar with flights flying out today and the next couple of days. They have J class but refuse to sell J on the routes. I think the only way to get J is to call in to change cabins once you see your seat change notification. I'm still waiting for a seat change notification for my flight as well.
yeah- It’s weird- not sure how they can love you to J when J=0. They have nothing to sell nor upgrade when it is all zeroed out.
A few days ago some of the changed flights were something like J9 C9 D4 Z2 P0 R9…. But the last couple of days they have just zeroed about the J cabin.
