Put Electronics, Medications, Toothbrush, and a Change of clothing in Your Carry-on A few important items should always go in your carry-on. A swimsuit is also a good idea if you are going on a beach vacation. You can buy most of these things if your bag gets lost, but having them in your carry-on will save you money and time if your luggage gets lost in transit. Stay Hydrated on Planes I know it’s fun to get drunk at 30,000 feet, but it’s also much easier to get dehydrated. Staying hydrated — especially on long-haul flights — makes it easier to get over jet lag too. Beware of Free Public WIFI I always try to avoid logging into bank accounts or entering any passwords while I’m using free public WIFI at a place like an airport. I’m not as strict about it once I’ve gotten to my hotel, especially if they have a password for their wifi. Alert Your Bank and Credit Card Company of Your Travel Plans This is a great habit to get into if you don’t want your credit card company or bank to put a hold on your card while you are overseas.
