I've recently been schooled on Fare codes, during some recent business travel. Info on Fare Codes is easy to find, and specific codes for most airlines are also easy to find.

I've yet to find a breakdown of Fare Codes for Southwest flights.

Goal here is to maximize my point earning while doing business travel. When forced to book through a client's travel agency, I'd like to specific the Fare Code Class I'd like a ticket in, to maximize my point earnings.
