LAX-MIA on a 77W (2 class) if that matters and I’m Plat.
Thanks

1) No, AFAIK, although there might have been some scattered reports of upgrade offers at check-in. I'll let others confirm.
2) No, for sure. If you could just pay the fare difference to a higher fare bucket or class of service then that would defeat the use it or lose it restrictions of BE.
