<p>I’m a frequent international traveler. </p>
<p>Noise cancelling headphones - try the foldable Sennheiser ones, not the huge ones.</p>
<p>Eye shades, inflatable pillow, and earplugs, so you can sleep.</p>
<p>I prefer aisle seats. When alone, on a plane with 3-3-3 configuration (3 sections of 3 seats per row), get an aisle seat in the middle section. Odds are high that the other two people are traveling together, and the middle seat person will bug their travel companion and not you.</p>
<p>Melatonin can help with jet lag.</p>
<p>Bring some food and water, so you can eat on your own schedule.</p>
