Bring all the things or forget the one thing you really needed. This is how it used to happen every time I tried to pack the perfect carryon. I’ve flown enough over the last four years that I think I have figured out all of my normal must-haves plus some tips that make flights a bit easier and definitely less stressful. There are certain things I bring on every flight (long or short) and a certain way I like to pack it to ensure I’m not digging in my bag while elbowing the passengers next to me trying to find something.
