Anything flammable, explosive or sharp is generally not allowed in your hand baggage. Remember to pack any sports equipment like baseball bats or tennis rackets in your checked luggage.

What to wear on a flight:

  • Whether traveling long or short-haul, layering up is key to staying comfortable. Choose loose, breathable fabrics that will keep you cool and pack a pullover to cope with any in-flight temperature variations. Your feet will be happiest in a pair of closed-toe shoes or sneakers.
  • Lessen your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for extended periods, by regularly moving 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.
