If your checked luggage didn’t arrive where you did, don’t panic. Ask any airport official where the lost luggage office is; have your documents from the flight and identification cards handy and fill out the appropriate paperwork. Your luggage will probably reappear soon, and they will get it to you in a timely manner. Consider drinking only bottled water if you are traveling to another country. Many countries do not purify their drinking water and this water can cause many different illnesses. Always use bottled water when brushing your teeth. You can also become ill from tap water.
If you are a visitor to foreign cities, keep your eyes open for thieves that might be dressed as law enforcement or government personnel. Don’t give anyone your original passport, because this could set you up for theft. If you are asked to go to an office with them, walk. Don’t ride with someone you don’t know. Get yourself a National Parks Pass if you think you will be visiting often. While the initial outlay is $50, they are valid for a one year term and give you open access to all national parks.
