Your passport, driver’s license, plane tickets, reservation conformation and itinerary should all be kept on you when traveling. You can’t get through an airport without a license, passport, or ticket, and if you lose your hotel conformation or itinerary, you may not know where to go once you have arrived at your destination. This is especially important if you will be traveling internationally. If you show up to a foreign airport without your passport or a copy of it, you are immediately considered a threat. Be sure to make multiple copies of your passport to keep in each bag of luggage.
Anything that is expensive or difficult to replace if it gets broken or stolen should definitely be kept with you at all times during travel. Jewelry, electronics and the security blanket you still can’t sleep without should all be packed safely away in your carry-on bag and stowed in your overhead compartment for the duration of your flight. You can buy a new pair of flip flops if you need to, but the watch your grandpa gave you isn’t easily duplicated. Don’t take the chance.
Anyone who has lost their luggage can tell you that it definitely pays to have another set of clothes in your carry-on. You never know how long you will be without your items. It’s smart to pack only the basics, that way you can accessorize the same plain top for each day or occasion, depending on how long you are without your bag. No one will know the difference. Also be sure to throw in a few extra pairs of undergarments, because unlike a T-shirt, you can’t wear those more than once.
Whatever can go wrong will go wrong, and when you’re freaking out because all of your belongings are on the other side of the country, the last thing you need is your phone dying. How are you supposed to figure out when your luggage will arrive if your phone is dead? Granted there will be a computer in your hotel, but if you were planning on punching the hotel address into your phone’s GPS, there isn’t a lot you can do.
Things like your toothbrush, makeup, contact solution and deodorant are always good to keep in your carry-on. Although they’re easy to replace if your luggage gets lost, they also can easily explode all over the brand new clothes you bought for your trip. No one wants to open their bag to find a huge blue Listerine stain on their pretty white bikini. Make sure to buy travel sized products, because anything more 3.4 ounces will be confiscated at security, no questions asked.
