A fully flex to OAK from SEA was 410 bucks rt and that was all that was avail when I last flew on a quick trip last week. A FC ticket was 440 RT, with a As50, it was a great use of miles for 1.5 eqm.
One way use of AS50 on a BOS F ticket is a fine thing as well.
I have also gladly paid the extra 50 bucks for an upgrade SAN-SEA on a AS50.
