This change doesn't really affect me as I usually end up with about $25K spend, miles are also a non issue, EQM are over 150K for me. So thinning out EXPs is a good thing.
However, I find EXP pretty useless. Usually purchase J or F tickets as I don't want to play the upgrade game. SWUs are useless, scarce availability to use for someone else or me at booking. Elimination of F on most international routes means I can't really use them unless I go to LHR for a J to F upgrade. New Flagship lounges are nice, but I'd get access with my international J or as a lifetime Platinum member so no perk there. First class check in has disappeared, now its all one big priority line with everyone who has an AA credit card or Gold. Flagship check in is ok when available and I'm traveling to a qualified destination.
