I can't find on the third party website — in this case, Vayama — what the purchased fare is for LAN (e.g., G, N, O, Q, S). Where can I find this fare code, for future reference?

Also, I called AAdvantage customer service and the rep said she can't tell without the fare code.

How can I be guaranteed that the base miles will be 100%, along with some kind of EQM?

I'm new to this and appreciate your help.
