I bring almost all this stuff with me on the plane when I fly. It’s a lot but often our bags don’t show up and I need to be sufficient for a few days!
A couple notes, the neckbrace replaces the common neck pillows you might see at the airport. It is much more effective and I really like it. My snacks on this trip were some cosmic cookies, with a bunch of carrots, green beans and snow peas. The book was an interesting story about an car driver in India who murders his master.
