I joined the DART program and have switched to UA! I was thinking about switching to AA but because of very specific route I usually fly on 3 times a year on awards (to DME), and a few other reasons AA did not work for me as a choice, so Im now a comped UA1P that will be aiming at UA1K sometime next year.
I agree with everything stated in the OP, and most importantly the useless PMU's (thats what broke the camels back for me). Just chose my E+ seats on the upcoming UA trip and looking forward to those SWUs once I hit 1K (and unlimited domestic upgrades in both UA and CO starting this Spring) !
