Separately, I thought $35 upgrades were only from full fare? Has that changed?
Edited to say -- apparently it has --
http://www.airtran.com/info/faq/index.jsp#inflight
<font face="Verdana, Arial, Helvetica, sans-serif" size="2">Business Class upgrades are available in advance for $35.00 over the full one-way coach fare for nonstop flights and for $70.00 over the full one-way fare for connecting flights. They are not available for use with discounted fares.</font>
But then it continues...
<font face="Verdana, Arial, Helvetica, sans-serif" size="2">Currently, as a special promotion, for the amounts listed above, you may upgrade from any fare class on a first come, first served basis, upon checking in for travel.</font>
