We’ve got the lowdown on how to make your journey an enjoyable experience. Follow our tips and you’ll be cruising through airport security and discovering Port-Valais in no time flat.What to pack in your hand luggage:

  • First, pack your passport, official ID, cash and vital medications. Next, you’ll want some in-flight entertainment to help pass the time. A juicy book and a phone crammed with your favourite shows are always good options. If you intend to take a short snooze, a comfy neck pillow and some earplugs will also be useful. Finally, make room for a toothbrush and some cleansing wipes to ensure you arrive at your destination looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Double-check that you don’t have sharp or pointed objects lurking in one of the zippers of your hand luggage. Other restricted items include flammable or explosive substances, such as fuel and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The best way to ensure a comfortable flight can be as simple as the clothes you wear. Prepare for changes in temperature by bringing layers. This will keep you nice and warm if the cabin begins to cool down. Shoes like sandals and heels are best left in your suitcase. Even though they may be your favourites, opt for flat, closed-toed footwear like slip-ons. Your feet will thank you later.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by reduced mobility or inactivity. There are numerous ways to minimize your risk. Wear a pair of compression tights or socks, stay hydrated and keep your legs and feet moving. Wander around the cabin or perform exercises in your seat.

How to get through airport security fast when flying to Port-Valais?
It’s all about being organised. We’ve compiled some handy tips and tricks for a fuss-free trip through security. Watch out Port-Valais, here you come:

  • First things first. Your travel documents and ID will need to be inspected by airport security. Have them close by to avoid fumbling around for them.
  • The X-ray machine is up next. Remove anything on you that is likely to set off the scanner’s alarm. 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 phone and tablet, must also be scanned.
  • Don’t forget to remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Pocket knives and other sharp items can’t be taken on board. They’ll be seized at security, so pack them in your checked luggage.
