Pro Tip: Carry less.
I travel a lot. Two weeks a month, at least, I'm on the road - in the air, in a car, walking, riding ...
I used to carry a rolling suitcase. It was big. It housed a couple of suites, several shirts, sundries, and all manner of shoes and gear and whatnot.
I now carry a briefcase. It's a backpack. It's rather small. It holds two good-sized files, computer, hard drives, and a full complement of pens, recorders, and other office supplies. I also haul a leather drop bag. It was made for me by my pal Susan Sherrick. It's simple and well constructed. It fits under the seat on a plane or easily into the overhead compartment. In it I carry a couple shirts, a pair of shoes, and a pair of jeans. I also toss in a dopp kit and undergarments for the week.
I wear a sports coat and, usually, dress shoes. I can have the whole affair mustered and packed for travel in about two minutes. I can carry the whole kit with ease.
