If you really want a meaningful response, do what I once did around 15 years ago: print out an old-fashioned paper letter and mail it to a bunch of senior AA managers. In my case, it was replete with photos of all the broken equipment that had negatively impacted my very expensive first class flights (plural). I addressed it to one specific executive and "Cc'd" all the others. I sent the letter via FedEx to the main recipient rather than USPS. The rest went out via certified mail. Not only did I get more miles in compensation than I ever have before or since, I got an apology phone call from one of the VPs.

I honestly do not make a habit of complaining to AA (nearly all of my grievances go on this forum only), and only do so when I feel it's really warranted. But if anything that egregious ever happened again, I'd consider doing the same thing.
