If you don't want to see this new "enhancement" and you're using FF...
get the ....... Plus Element Hiding Helper add-on and add this line to your Preference file:
flyertalk.com##table[cellpadding="3"][cellspacing="0"][border="0"][width="100%"]
I received a PM that my little fix breaks the "airport code lookup" quick-link. If you don't use this feature then there's no need to change anything.
However, if you do use the "airport code lookup", you may want to replace the above Element Hider statement with this one:
flyertalk.com##div.tborder
