Travel in loose-fitting, comfortable clothing since you will swell up on a long flight; wear shoes that are easy to remove for both security screening purposes and for comfort on the flight.

Remember TSA restrictions regarding carry on items, including limitations on liquids and gels (containers of 3 ounces or less, all must fit within a quart-sized zip lock bag, and each traveler is limited to one such bag).

Do not attract undue or unwanted attention to yourself by engaging in behaviors that can mark you as a tourist, and thus as a target for pickpockets:

  • don’t wander around with your face buried in a guidebook or behind a huge map – instead, stop for a moment to consult them in an out-of-the-way spot
  • don’t pull large amounts of cash out of your pocket (keep a small amount of cash in one pocket, and if you must carry more, keep it elsewhere on your person)
  • do not wear flashy jewelry
  • don’t yell inappropriately or converse very loudly in public places

Remain aware of your surroundings at all times: know where you are and where you are going, don’t travel alone if you can avoid it, and make sure you don’t get separated from your companion(s).

To the extent possible, adapt to local standards of dress. If no one else is wearing shorts and flip flops, you shouldn’t either – to do so will make you stand out like a tourist. Note that wearing sneakers and a baseball cap has the same effect in many countries.

Be discreet and respectful when taking photographs. If you want to photograph people, ask for their permission first.

Carry a list of emergency contact numbers (local and at home) with you at all times.

Make sure someone else always knows your travel plans.
