The "Review Ticket Details" page (reviewRevenue.aspx) always says "This ticket is refundable," even for non-refundable fares.

All fare classes including A, C, D, J, and Z appear as "Coach".

Error messages such as "Continental doesn't serve that airport" are missing. Where the page used to show an error, and still does on (for example) car searches, there is now just an empty line in the HTML, like this: <span id="ctl00_ContentInfo_OandD_Destination_lblFieldEr r" class="fError"><BR></span>
