A favorite joke of many of us in the travel industry goes something like this. A traveler goes to the airline check-in counter and tells the agent, "I'm going to Houston, but I want you to send one of my suitcases to Dallas and the other one to Washington, D.C." The agent shakes her had and says, "I'm sorry, we can't do that." The passenger says, "Why not, you did it last week?"
