How to survive the flight to Sion?
We've got the lowdown on how to make your flight as enjoyable as possible. Follow our insider tips and you'll be speeding through the airport and enjoying Sion in no time at all.What to pack in your hand luggage:

  • First, pack your passport, travel documents, wallet and vital medications. Next, you'll want some entertainment to while away the time. A thrilling novel and a laptop crammed with your favorite shows are good options. If you hope to catch a few z's, a neck pillow and some noise-canceling headphones will also come in handy. Finally, leave some space for a few toiletry items so you'll touchdown feeling fresh as a daisy.

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 compartments of your carry-on luggage. Other restricted items include flammable or explosive goods, such as aerosol cans and bleach, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your goal here is to be as comfortable as possible. Layer up with loose, breathable clothing and pack a cardigan in case you get cold. Go for a pair of flat, slightly roomy shoes as it's possible that your feet and ankles will swell a little during the flight. Leave the high heels and hiking boots in your checked baggage.
  • Unfortunately, a risk of flying long-haul is developing DVT (deep vein thrombosis), a blood clotting condition caused by prolonged inactivity. To prevent this from happening, take every opportunity to walk around and give your legs a stretch. Compression socks and tights are another easy way to help reduce this risk.

How to get through airport security fast when flying to Sion?
Being prepared before you get to the airport will help make your getaway to Sion a piece of cake. Check out our useful tips for a speedy journey past security:

  • Be sure to keep your ID and boarding pass within close reach. They'll be the first things you'll be asked for by airport security.
  • The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes things like earphones or headphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • All electronic gadgets, including your laptop and phone, must also be scanned separately.
  • Traveling with your favorite cologne? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on luggage.
  • Slip-on shoes are a good footwear choice as you're less likely to be required to remove them when going through security. Safety boots and other bulky shoes are usually subjected to extra screening.
  • Airlines will not allow any sharp or pointed objects to come on board with you. If you need to bring these kinds of items, put them in your checked luggage.
