We always fly AA, and have had two times when they included the departure tax, and a whole bunch when they didn't. I think it depends of where you book, through the AA system, or through a booking agent. Sometimes, on places like "cheaptickets.com" they will say price includes all taxes and fees. In this instance, they should be included. Read the fine print if you buy online. One never knows, tho, until you pass through that line on your way out. Better to keep a bit of $$ tucked in the passport, just in case.

Live so that when you arise in the A.M, Satan shudders & says..
'Oh sh t..she's awake!'
