1. There’s no rule here. TK can do whatever they want. I had a flight which for months didn’t have J class availability and a few days before the flight they release a few J class seats.
2. Never heard about this rule (the part I quoted). In fact, I managed to upgrade many times with this “rule” not interfering.
