I didn't get the survey. Multi-year EXP, but the number of times I have purchased Y on a flight with F is near zero so I rarely experience UDUs. At this point, AA is down to about 70% of my flying as I switch to whomever has better times, non-stop routes, or a marginally better aircraft. As a NY-based traveler, AA, B6, and DL all are viable choices on most transcon routes. And for mid-con routes they all tend to suck, but some suck with a connection vs. without. AA seems determined to wring the last shred of value out of EXP, which wrings the last drop of loyalty out of me.
