1. Keep Your Photo Identification Handy. If you do not have photo identification, make sure you have two pieces of some other form of identification, one of which must be issued by a government authority. Minors are not obligated to have identification. Failure to have proper identification may result in additional security inspection and search. Some airlines may also prohibit you from boarding without proper ID. For international flights, airlines are required to collect your full name and ask you for a contact name and phone number.

2. Give Yourself Some Extra Time During busy hours, or when traveling. With elderly or disabled passengers, young children or infants, give yourself more than enough time to maneuver through a busy airport or to make necessary arrangements with airport personnel.

3. Do Not Park Your Vehicle and Left Unattended in Front of Terminal. The airport parking rules are being strictly enforced and your vehicle may be very swiftly ticketed and towed. So make sure to park in well-lit, designated areas. Find a parking garage or lot you are comfortable with and is well populated.

4. Know What You Have with You. Watch your bags all throughout airport terminal, shops, and lavatories. Don’t accept packages from strangers or persons who you might have a casual conversation with. Be prepared to answer questions about who packed your bags and whether you might have left them unattended at any time. Focus carefully and answer honestly—previous history has shown terrorists and criminals use unaware passengers to carry bombs or other dangerous devices on board an aircraft, either by deceiving passengers into carrying packages or by slipping items into unprotected bags. If you’re unsure, make it known to airport security personnel.

5. Beware of Unattended Packages. If you see an unattended package, bag or piece of luggage in terminal, report it to airport security staff or other airport personnel immediately.

6. Don’t Fool Around. Don’t joke about having a bomb, firearm or weapon with you. Security personnel are trained to react when they hear these words. Punishment can be harsh and can include possibility of time in prison and/or large penalties and fines.

7. Anticipate Having Your Bag and Luggage Searched. Both carry-on and checked bags are subject to being hand-searched, especially when airline security personnel cannot determine by X-ray machines contents of one. Keep gifts unwrapped until after you arrive at your destination. Airline security personnel will open it if X-ray machines are unable to identify contents.

A solo backpacker also is vulnerable. Twist your ankle, and there's nobody there to help you. Have you ever been stuck alone without food for days? How can you make your solo backpacking trip safe? You can't. It's inherently more dangerous to go alone into wilderness. What you can do though, is make it safer.

Some Solo Backpacking Tips

1. Tell someone where you'll be, and when you expect to return. It's probably best if you leave a map with them, and let them know who to call if you don't return on time.

2. Bring a cell phone. I don't do this yet myself, but many lives have now been saved by cell phones. Turn it off and put it in bottom of your pack so it won't bother you.
