Mrs prometa and I are headed RT to CDG next week, on different PNRs because my ticket is employer paid. Both R/K tickets.
interestingly, my price for cash upgrades is $1000 less to go J to CDG ($2200 vs $1200) and a few hundred cheaper for R or J on the return, each. I am plat, she is GM. Hadn’t seen reports of variable pricing in a while—at least this variability is in the direction you’d want.
