Do you have any tips for my flight to Sion?
Wherever you're coming from, flying can be a seamless experience if you've planned ahead. We've compiled a list of handy tips and tricks that will get your Sion holiday started on the right foot. What to pack in your hand luggage:

  • A plane trip can be a comfortable experience if you've got all the right gear. Firstly, you'll need basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a fresh set of clothes and a good novel. Next, make room in your bag for your electronic devices, chargers, your important medications and maybe a blow-up neck pillow too. Last, but definitely not least, be sure to take your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a Swiss Army knife lurking in one of the zippers of your hand luggage. Other prohibited items include explosive or flammable goods, such as fuel and fireworks, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your number one priority when choosing what to wear on your flight. Loose, breathable clothing is a sensible choice, as are flat, enclosed shoes.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clotting due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to Sion?
The trick is to be well organised before you arrive at airport security. That way, you'll be boarding that plane to Sion before you know it. Follow these tips and get your holiday off to a spectacular start:

  • Be sure to keep your boarding pass and passport close by. They'll be the first things you'll be asked for by security.
  • Time to strip down. Well kind of. Your coat, belt, keys and other contents of your pockets, like your headphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • Your electronic devices like phones and laptops will also need to go on a tray for inspection. Don't worry, you'll be back online before you know it.
  • Can't travel without your favourite hand and nail cream? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can keep it with you in your carry-on baggage.
  • Lightweight sneakers are a good footwear choice as you're less likely to be asked to remove them when going through security. Hiking boots and heavier-style shoes are usually subjected to extra screening.
  • Airlines won't allow any pocket knives or other sharp items to come on board with you. If you need to bring these kinds of items, pack them in your checked baggage.
