The United States Coast Guard is part of the Department of Homeland Security rather than the Department of Defense. This distinction probably wasn’t what a U.S. Airways employee had in mind when refusing to waive Jennifer’s baggage fees, though. Jennifer was returning to her station from a trip to visit family, but the employee insisted that she had to pay a baggage fee like civilians do, because the Coast Guard isn’t part of the military. A manager agreed, but they were both wrong. Jennifer didn’t need to pay to check her bags, and members of the Coast Guard have served in just about every war in American history. They certainly are part of the military.
