Yeah, I'm thinking "fell in a crack." I'd expect ET to initiate, because they're the ones who would benefit from MP members booking their flights, and also because they'd know if they introduced a new booking code.
I can't imagine that the people who would reach out to ET to verify earnings would have permission to override the table. It's much more likely that they just send a request to ET and get a response back that says "yes, jsloan flew ET1234 in class P and hasn't credited it to any other program," and then they look up the earnings table for ET, see 0%, and deny credit.
