Wear clogs, not sneakers (in case you have to go through security) dress in layers (airplanes are usually too hot or cold) travel as lightly as you can (I have NOT learned this YET but I am working on it) and most importantly, ALWAYS BRING A LOT OF FOOD. We used to bring elaborate home-made sandwiches and snacks, beverages and dessert to keep us happy but that rule changed too. I usually am a snob about airline food especially after I got food poisoning after a meal in the sky. So, Adapt: Buy food after security, a lot of it and of course, buy chocolate. A lot of chocolate. Take Dramamine and keep it in a very handy location. Just sayin……..
