Comfort first. The most comfortable clothes work both for getting on the plane as well as staying healthy. While you want shoes that you can slip on and off while in the security line, cold air can make for an uncomfortable plane ride for your toes. But lacing up in too restrictive footwear can also be uncomfortable if you experience swelling. Have a pair of travel-friendly socks in your carry-on so you can sport them while you’re in flight. Your clothes should be easy to wear for an extended time too; wear comfortable layers in case you get too hot or too cold, and avoid extra zippers or buttons, which can impede you while you try to find a comfortable position.
Snack attack. Bringing your own healthy meals is easier to do when you’re flying domestically, but when you are in for an overseas flight, you may be at the mercy of the galley kitchen’s offerings. If you’re taking an overnight international flight, try eating before your plane takes off and bringing healthy snacks so you don’t have to eat the heavy dinner offerings. Or check out these airlines with the healthiest on-board fare.
Germ fighter. The air in there may not be as dangerously full of germs as you may think — in fact,airplane air is often filtered more often than the air in most office buildings — but that doesn’t mean you’re not more susceptible to diseases when you’re up in the sky. While the coughs and sneezes of your fellow passengers may not make you ill, the fast turnaround times between flights means that certain areas on planes don’t regularly get disinfected like they should. Carry a bottle of hand sanitizer for a quick wipe down of your area when you first sit down.
