I don't see the changes on the site but brought up the webpage code and did a search for million. I see in two places:
<div style="margin: 0px;display:none" id="millionMilerTooltipContent">
AAdvantage miles earned through select mileage activity count toward Million Miler<sup>SM</sup> status. <br />
The Million Miler program rewards AAdvantage members with additional benefits when specific mileage thresholds are achieved.<br /> To learn more, read about the <a href="/homePage.do">Million Miler program</a>
</div>
<!-- -Added Code for Million Miler -->
<div id="pbnMillionMilerMilesBody" class="topNegative10 displayNone" >
<!-- Condition for checking MillionMilelevel code If Code is null or not -->
<table id="tblpbnMillionMilerMilesBody" width="100%" cellspacing="0" cellpadding="0" summary="Mileage Activity table" class="zeroTopMargin">
