here's the comment for Barb's reply to this question earlier this month:
***********************
Almost all the airlines include the $35 departure tax now. USAir is the only one I am aware of that does not. If the taxes add up to about $80 or $90 or more, it is included (unless they have a lot of extra stops on the flights). If they add up to $60 or so, it is not included. The $35 BZ dept tax also breaks down into a few different taxes with code letters, one of which is the "FU" tax (really!) If you see that with a dollar amount before it, it is most likely included.
Should look something like this (with BZ dept tax included):

7.50AY 15.00FV 1.30FW 3.80FU
15.00BU 4.50XF

I have an upcoming FF tcket & taxes were $60.06 and do include the FU tax so go figure.........

The taxes vary airport to airport so who knows what the threshold is to know if its in or not simply by looking at the $$.....the code is there, so I guess I' set, but ya know.....$35 ain't gonna stop me one way or the other!!!
Me thinks also that since most are now incldued, those few old tix still out there have a real good shot of not having to pay as agents become acclimated to current situations.
