My wife, my 1 hear old son and my niece flew out of DFW on January 6, 2018. We flew on American Airline. The TSA agents confronted us and confiscated our son’s aseptic milk (two bottles of 8 oz each, that were sealed). The agent also confiscated, one bottle of 16 oz open water, which we purchased at the airport. The agent also had the audicity and the cruelty to empty my son's water cup. I challenged the agent to allow me keeping the product and she denied it. Her claim was that my son was old enough if he could walk. The agent was extremely rude to us. I begged the agent to allow us keeping the water in the cup in case of a delay but the agent was completely sensless. I asked to do a pat down and kep the items and she denied me. I asked to speak with the supervisor. Ten minutes later a rude, dismissive, racist human being identified herself as the supervisor. The supervisor seemed to have a problem with us being white. I proceded to tell her we fly quite often and this was the first time we faced this issue at DFW airport. She was quite dismissive and did not care to listen what I had to say. She took off without reacting. I asked her numerous times for her ID. She finally mumbled STO CLARK. For the last 30 days we have taken three trips out of DFW and we have been allowed to bring water, milk, and yogurt for my son to eat. The last time we traveled was on December 17, 2017 and we did not face any ssues. The professionalism at DFW airport on this date was completely lacking. We have never experienced this situation anywhere else in te US. I am in the airline industry and as much as we travel, we have never faced this cruelty before. If our flight got delayed my son would not have any food or water to consume. Additionally, my son waited until we got up in the air and approximately 1 hour after take off to get water since the flight attendants could not get on aisles due to the turbulence. My son was crying as he was thirsty. Shame on TSA agency for depriving a 1 year old from essentials of his life, water and milk. They left my son without milk or water for a long time.
