Thanks for the replies. When I started the thread, I was concerned with balancing PQM vs. PQD. With the CC waiver through Plat, now I need to determine just how much Plat is worth to me. On paper, there doesn't seem to be much difference between Gold and Plat, but comments at FT suggest Plats get quite a few more upgrades over the course of a year.
The upcoming flight I mentioned is three segments of 2:20, 2:50, and 2:10, so they're right at that duration where F / J becomes a little more tempting.
