There's the SAN-FLL fare for $170 all in; can get up to 6K EQM, 12 EQM after the double up. You have to look a bit to find more than 1 connection to get around 6K. Not necessarily the best flight time either. Don't forget the fly 3, get 25K mile bonus.

Do 2 of those, and get around 24K EQM; a bit cheaper than LON, though you won't get bangers and mash.
