  • Get your trip off to a flying start by being prepared. Pack your travel documents, passport and medications first. After that, think about downloading some new movies on your tablet or phone for a guilt-free binge session. Or, throw in that novel you’ve been itching to read. Lastly, a snack or two to nibble on and a good-quality neck pillow will go a long way to making your flight as comfy as possible.
  • It also pays to check with your airline regarding what you can’t take on board your flight. Knives, razor blades, swords and batons are among the prohibited items. Anything explosive, sharp or flammable is generally not allowed in your carry-on baggage. Don’t forget to pack any sports equipment like ski poles or baseball bats in your checked luggage.

What to wear on a flight:

  • The aisles of a plane aren’t designed for a fashion parade. Layer up with comfy clothing and pack a pullover since it can get cool in the cabin on long-haul flights. Enclosed, flat shoes are the best type of footwear for longer journeys.
  • Lessen your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for lengthy periods, by regularly walking around the cabin. Alternatively, do some gentle lower limb exercises in your seat. If you’re at higher risk of developing DVT, think about wearing compression socks or tights.
