I was booked into A for an itinerary last week, actually. When the flights initially posted, they were listed as "A" on the Miles/Points column of my OnePass Statement and gave me 1.5 EQP, but only the base mileage for EQM. However, I noticed this morning that my EQP total went down, so I again checked my statement. Turns out those flights have had their fare code replaced with ZH... as if I were upgraded via the complimentary elite upgrade system, on an H fare ticket.
The fare basis was one of the H-UP type fares, but it was always listed as an "A" fare. And since it was purchased (domestic) First class, I'd think it should get the bonus EQM/P... though of course the website does not, as noted above, actually list the A fare anywhere, so its a hard case to make.
Might have to reach out to CS to ask about this.
