1. Check-in with your doctor and insurance carrier. Double check and make sure that you have all of the proper vaccinations and that you have renewed all essential prescriptions. Also, ask you medical insurance provider if your policy applies overseas for emergencies. If it doesn’t, and you want to add extra coverage, consider supplemental insurance.
When you travel, you’re in the sun more than most people thanks to months of island hopping and beach time, and entire days spent outside exploring. Wear sunscreen every single day, regardless of the weather and temperature, because you really don’t want your trip of a lifetime to result in skin cancer. Plus, it prevents premature ageing! I wear sunscreen every day, even in the middle of winter.
As the TSA screening protocol has expanded, I've found small ways to save time during airport screening; I make sure that metal (watch, keys, change, phone, etc.) is in my computer bag - not on my person. And since airport requirements differ, I always assume the TSA will need to see my boarding pass a second time. Finally, for those wearing dress shoes through airport security, consider trading in your laces for a pair of slip-ons. You never know when you may need those two minutes you'll save.
Even if you don't normally use lip balm, it can still be an important item to pack. Breathing dry airplane air, being out in the sun, eating salty foods in transit—travel inevitably leads to mild dehydration and chapped lips. And there's something off-putting and vaguely predatory about constantly licking your lips. Lip balm can also be used to tame frizzy hair ends, soothe dry cuticles, protect skin from windburn, and even unstick a stubborn zipper.
