Remove the Distractions
Tune out the hustle and bustle of the airport through sensory deprivation. Use an eye mask, earplugs, headphones, and a neck pillow, and then drape a sweater or blanket over you. (It's not for everyone, but you might also consider an Ostrich Pillow.) To avoid being a target for thieves, it's best to do this only when you're with a travel partner who can keep an eye out.
