How to survive the flight to Silex?
Depending on where you're coming from, your trip to Silex could be completely painless or it could go on forever. Here are some handy hints that will help you start your next big adventure on the right foot.What to pack in your hand luggage:

  • First of all, put in your passport, official ID, credit cards and vital medications. Next, you'll want some entertainment to while away the time. A juicy book and a laptop filled with your favourite shows are some great options. If you plan to take a quick snooze, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, make room for a few toiletry items to ensure you step off the plane feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between air carriers, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes tools, metal cutlery, spray paint and flares. Sporting equipment like bows and arrows, and items that could injure passengers, such as firearms and ammunition, won't be allowed on board either.

What to wear on a flight:

  • The long, narrow aisles of your plane are no place for a fashion parade. Layer yourself up with comfortable clothes and pack a cardigan as it tends to get cool in the cabin during long-haul flights. Closed-toed, flat shoes are also a good idea.
  • Unfortunately, one risk of flying long distances is developing deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity. To prevent this from happening, make the most of every opportunity to wander around the cabin. Compression socks and tights are another easy way to help reduce this risk.

How to get through airport security fast when flying to Silex?
A little pre-planning before you arrive at the airport can make your trip to Silex a piece of cake. Check out our handy hints for a speedy journey through security:

  • Airport security personnel first need to establish that you have a valid passport and matching travel documents before you can proceed any further. Have them close by, ready for inspection.
  • After that, both you and your carry-on bag will be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Items such as your belt, coat and headphones need to go through the machine.
  • Electronic devices like phones and laptops will also have to go through the machine to be scanned. Don't worry though, you'll be back online before you know it.
  • Remember to remove gels and liquids from your hand luggage. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
  • There's a good chance you'll be required to remove your shoes to be X-rayed, so wearing slip-on shoes is always a wise idea.
  • Airlines won't allow any sharp or pointed objects to come on board with you. If you must bring these kinds of items, pack them in your checked baggage.
