I've had 3 762 flights since 1/15, all without power ad all upgraded from coach fares. Only one came with a proactive contact from AA CS. I sent an email about one other and received appropriate compensation. The last of the three was just a couple of days ago, so I'm going to wait to see what, if anything, posts.
One question for the wisdom of this particularly knowledgeable crowd though: I have at least another 7 762 flights between now and the end of March. My plan is just to send one email at the end of them requesting bundled comp. Anybody have any thoughts as to whether that would be met with a better reception than emailing after each flight and trying to get myself into the auto-comp "system" that currently seems to be very, very hit or miss?
