How I pack my carry on for a long trip, but a short flight is quite easy; it starts with the bag. Our next trip is for a two week vacation but only about a 6-hour flight, which is relativly short. When it’s an extended vacation like this, I usually pack a larger carry-on plus a checked bag. So my carry on like most people is my most valuable things and necessities. For international flights, I do change up my carry on bag and my packing in general but more of that to come later.
