It depends on what terminal your flight is going out of. Before you fly type into Google the 2 letter code for the airline your flying then the flight number Example if your flight is American Airlines flight 339 to Phoenix. In the Google search bar type in " aa339 " and it will tell you the gate and terminal. When you get through TSA check again and often. Since the gates change constantly. They try to stop changing the gate an hr before boarding time. Good luck
Wonderful airport too flying in an out of staff is very friendly and knowledgable
