Lastly, and most importantly, be sure to bring your passport, travel docs and your credit cards.
Do not pack the following items in your hand luggage:

What to wear on a flight:
  • The narrow aisles of an airplane are not the best place for a fashion parade. Don comfortable layers and remember to take a cardigan as the temperature can drop inside the cabin. Flat, enclosed shoes are also a sensible choice.
  • Most travelers have heard about DVT (deep vein thrombosis), a blood clot condition caused by reduced mobility or inactivity. There are numerous ways to reduce your risk. Wear a pair of compression tights or socks, drink lots of water often and get your legs and feet moving. Do a lap or two of the cabin or perform some stretches in your seat.

  • All your electronic devices, including your phone and tablet, are also required to be scanned separately.
  • Want to bring along your favorite perfume or cologne? As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to be asked to remove them when passing through security. Hiking boots and other heavy-style shoes are often subjected to additional screening.
