Callie said she carries it all on board with her because she doesn't want anyone going through her things when she isn't watching. I also only take just what I can carry on but its because I want to know where my luggage is at all times. If you have a flight delay or misconnection, for reasons that seem to be compounding, you never have to worry if you will ever see your luggage again, and if so, when. I also have an easy time getting around with my belongings in tow as I don't have much with me. Now, if I should go on a ski trip - all of this changes !

Best to you all, Cathia
