Sleep Aids — Trying to get some sleep on a long-haul flight without the comforts of a pillow or sleep aid may seem next to impossible. So don’t forget to bring a neck pillow and an eye mask; even sleeping tablets may help.
Noise-Canceling Headphones or Earplugs — It’s every traveler’s wish to have a peaceful flight sans crying babies, loud-talking passengers, or someone kicking the back of your chair.

Earplugs can also help reduce pain from a change in altitude. Check out CNET’s recent review of the Best headphones of 2015 and the Best noise-canceling headphones of 2015.
