This works originating in DAL as well, with much more availability. Also consider flying in F using promo code BALLER20 (20% off base F and MCS fares) for $245.50 RT, example date May 6. It reprices down from a higher fare on VX.com once you select a seat.

This mini-trick is all gone now, everything is normal priced, but it was fun while it lasted
