Travelling light.

Or traveling. When I have the chance to travel I always carry only a shoulder bag. Never a suitcase (load-on load-off....and a pain to carry around). Not even one of those some "small" carry-on type "suitcases" on wheels. They barely fit in the ailse, sometimes don't even fit in the overhead bin and have to be taken out of there. And I never carry more than 5 days worth of clothes (they always have washing and drying machines....or equivalent, at the other end, I suppose, if unless you are going to the boonies . Plus, you never have to wait at the baggage drop and see if, luckily, your suitcase will be there. Haven fun.
