What to wear on a flight:

  • The key to a comfortable flight often lies in the clothes you wear. Prepare yourself for varying temperatures by bringing layers. That way you’ll stay nice and warm if the cabin begins to cool down. Shoes like stilettos, flip flops and lace-up boots are best left in your checked suitcase. Even though they may be your favorites, opt for flat, closed-toed footwear like slip-ons. Your feet will thank you for it.
  • It’s likely you’ve heard about DVT (deep vein thrombosis), a blood clotting condition caused by long periods of inactivity. There’s lots you can do to minimize your risk. Wear a quality pair of compression socks, drink plenty of water and remember to keep your legs and feet moving. Wander up and down the aisles of the cabin or try out some exercises in your seat.

  • Any gels or liquids, such as perfume or toothpaste, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one liter), clear zip-lock bag.
  • There’s a good chance you’ll be required to take your shoes off for scanning, so wearing lightweight sneakers is always a smart idea.
