Do not depend on airport or local Wi-Fi
You may be used to a hyper-connected world, but not every airport or locale is up to your speed. To avoid problems, print out boarding passes, hotel, and travel information and make them easily accessible.
Look at the CDC Travelers’ Health website
This site dispenses warnings about any health threats, such as typhoid, Dengue fever, and malaria, with medical remedies to counteract them and required vaccinations.
Check the US State Department website
Remember to log on to the U.S. State Department’s travel website to find out about travel advisories and danger zones.
Set up fare alerts on travel sites
Travel aggregator sites, such as Kayak.com or Travelocity.com, offer you a way to track flight prices. You can have price alerts emailed to you with the frequency you desire. Most sites will also tell you whether the current price is high, low, or typical for the time of year you’re traveling.
Review your health insurance coverage
Never travel without reviewing your health insurance and checking whether it covers you abroad. Some U.S. health insurance plans and Medicare do not, but you may be able to buy supplemental international health insurance. Some Medicare Advantage and Medigap plans offer emergency care overseas, and companies — such as SquareMouth, QuoteRight, and InsureMyTrip — also sell travel health insurance. As a backup, however, you should have cash in the local currency on hand to pay a doctor’s or hospital bill.
