Why I hate giving American airlines my cash

I've had elite status in American Airlines for a few years now, actually it started with USAir and it was a good program then but has got nothing but worse since the merger.  I was often upgraded on USAir, not anymore, and the way they make your pay for upgrades now is crap, coupled with there ever decreasing focus on the customer, I can't wait to stop using them.  I have paying my own money (not business funded travel) every month for 5 years.  There relative suckiness was brought home again tonight as I fly on a United flight tomorrow on which I've been upgraded for free.   United recently matched my elite status on United based on my American Status.  I haven't flown United in years and despite that I was just upgraded, same thing happened with Alaska a few months ago.  Free upgrades on two airlines that matched my American Status but I have to pay for any upgrade on American or wait a ridiculous amount of fights to earn credits despite  spending 10s of thousands of my own cash.   United and Alaska have treated me better based on my American Status than American has.  I can't wait to be done with them and will be soon and will do everything I can to never give them a dime again.  United and Alaska treat me better than American does...
