Do you have any tips for my flight to Defiance?
If you're poorly prepared, air travel can be testing. But there's no need to worry. Follow these handy hints and enjoy a hassle-free start to your time in Defiance. What to pack in your hand luggage:

  • The secret to having a worry-free flight experience is to be prepared. Start with the essentials: passport, travel docs, cash and any vital medications. Next, take on board items that'll help keep you busy, like your laptop or a good read. It's also a wise idea to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. Last but not least, be sure to squeeze in toiletry items like a toothbrush, deodorant and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between airlines, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes things like tools, metal cutlery, aerosol cans and flares. Sporting equipment like hockey sticks, and objects that could harm other people, such as swords and guns, are also banned from the cabin.

What to wear on a flight:

  • Your main aim is to feel as comfortable as possible. Opt for easy-to-remove footwear, dress in loose, natural-fibre clothing and don't forget to take a sweater in case you get cold in the cabin.
  • Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long flights. Reduce the risks by staying hydrated, keeping your legs and feet moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to Defiance?
It's easy --- be prepared. We've pulled together some useful tips for an easy trip through security. Watch out Defiance, here you come:

  • Be sure to have your ID and travel documents within close reach. They're the first items you'll be asked for by airport security.
  • Your coat, belt, keys and other contents of your pockets, like your headphones, will be required to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronic devices will need to be sent through the scanner.
  • Travelling with a new cologne or perfume? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, it's fine to bring with you in your carry-on luggage.
  • Choosing your footwear wisely can save you valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Lightweight sneakers usually aren't.
  • Airlines won't allow any sharp items or pocket knives to come on board with you. If you need to bring these kinds of items, check them in.
