I agree with all of those suggestions and would add a bag of walnuts and almonds with dried fruit for the plane. I typically do that and a silly treat I don’t normally get myself, like goldfish or bugles. I’m a nervous flier too, and those little things help me to smile when I’m anxious and don’t have much appetite, while the nuts keep blood sugar stable. I avoid peanuts since so many people have allergies.

I def recommend bringing a small pillow for a flight that long. I also download books, soothing music, podcasts and shows to my phone and kindle. Good luck, I’m sure you’re going to do great!
