They have only been including the departure tax ($20) on new tickets purchased since about Dec 2003. Now they will be adding in the new $35 dep tax on tickets purchased from now on. So if you purchased tix within the last few months, they probably will have the old dep tax included but you will have to pay the $15 difference. If you purchase tickets from now on, they will have the $35 dep tax included. Except USAir which has not been including the old or the new dep tax and you will have to pay the $35 at checkin.
