Maximing Travel baggage Space

If you are having trouble fitting everything in, look for ways to use nooks and crannies. Fill the area around books with socks. Put your ethernet cables inside your shoes.

Also, you can cheat a little bit on the carry-on. Wear your jacket on the plane instead of putting it in your suitcase. (This is not a bad idea anyways, since airplanes are frequently cold.) Put your earrings, modem, or even a few pairs of underwear in your coat pockets.
