Pretty sure we paid a departure tax leaving STT by air because we sent our kids (adult kids) through security etc separately because they were on a different airline than us. Met up with them after security and they were like " we had to pay money to get out!" It was the first time during the trip thy had to get their wallets out <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />
