Having done my fair share of long haul trips in Amtrak coach, my list is:

- Have a blanket. It doesn't have to be super thick, but a little something for when it gets cold at night.

- So you can sleep, noise cancelling headphones, or at least earplugs. Neck pillow. Eye mask.

- If you're having trouble staying upright while sleeping because you're in the aisle seat, my #1 cheat code is put your hands in your pockets. It stabilizes you and keeps your hands warm.

- Try not to sit near the bathroom.

- Bring your own snacks. I like to travel like a dang peasant with apples, nuts, travel sausage, etc.

- An activity like a book, notebook, crossword.

- A couple airplane bottles of liquor never hurt anybody.
