I've done this for years...if I am purchasing last minute then I fly WN because they reward me accordingly...if I am flying cheap fares I fly US because I get rewarded better. For example RT from PHX to ELP on WN last minute I'll get over 16k points right now (I'm A-List preferred and they have a double points bonus going on as well) same flight on US I net 1.5k (I'm US Gold)... but a cheap fair I get about 1.5k on either...what's more valuable...I would happily switch everything to US/AA if they rewarded me for the $'s spent but until then they will keep getting inexpensive fares and WN will get my high $ fares...anyone who is
