We've got the lowdown on how to make your journey a stress-free experience. Follow our tips and you'll be hightailing it through the airport and exploring Thornfield before you know it.What to pack in your hand luggage:

  • The trick to having an amazing flight experience is to be prepared. So, let's start with the essentials: passport, travel docs, cash and medications. Next, bring items that'll help pass the time, like your laptop or a good book. It's also wise to pack your chargers, a neck pillow and a pair of noise-canceling headphones. Last but not least, don't forget to chuck in toiletry items like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a sharp object lurking in one of the zippers of your hand luggage. Other banned items include explosive or flammable substances, such as fuel and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The long, narrow aisles of your airplane are not the place for a fashion parade. Wear comfortable clothes and remember to take a cardigan as the temperature can drop in the cabin. Slightly roomy, flat shoes are always a good idea too.
  • The serious condition by the name of DVT (deep vein thrombosis) can pose a risk on long-haul flights. It results from blood clots forming due to poor circulation. Doing leg and foot exercises in your seat is a great way to prevent this occurring. Wearing a good pair of compression socks or tights is also recommended.

How to get through airport security fast when flying to Thornfield?
It's all about being organized. We've put together some handy tips and tricks for an easy trip through security. Look out Thornfield, here you come:

  • Airport security personnel first need to determine that you have a valid passport and boarding pass before you're allowed to proceed any further. Have them close by, ready for inspection.
  • The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
  • All electronic devices, including your tablet and phone, must also be scanned separately.
  • Any gels or liquids, such as lip balm or cologne, that you want to bring on board must be no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-lock bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to be required to remove them when passing through security. Safety boots and other bulky shoes are usually subjected to extra screening.
  • Sharp or pointed objects (like knives and scissors) are prohibited in the cabin. They'll be confiscated at security, so put them in your checked luggage.
