Not only does packing everything in a carry on let you breeze through the airport, but it makes traveling in general so much more pleasurable. No more wardrobe melt-downs. No more lugging around cumbersome items on cobblestone streets.
Traveling long hours can be annoying, tiring and uncomfortable. Sitting on a plane for hours in a tiny chair with no leg room sucks, especially if you’re wearing something that is NOT comfortable. When traveling you want to be comfortable and relaxed.
