Thanks for your reply.

If this is the case I understand from a business perspective, but from a customer perspective it is disappointing.

I arranged these dates back in September for upgraded travel as they were originally going to be on the 787. Then they took off the Dreamliner and replaced it back to the 764, which is fine. Now, with a further downgrade to the 76H, I feel I am wasting my GPUs. In addition with no Y+, it is even worse.

As of yesterday there were still 16 C seats open.
