Start with the essentials: passport, travel docs, credit cards and medications. Next, bring items that'll help while away those hours, like some electronic gadgets or a juicy novel. It's also smart to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. And of course, be sure to squeeze in toiletries like a toothbrush, lip balm 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 your carry-on luggage. Other banned items include flammable or explosive substances, such as aerosol cans and bleach, and gels and liquids in containers larger than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Comfort should be your top priority when deciding what to wear on your flight. Loose, breathable clothing is a smart choice, as are flat, enclosed shoes. > - Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some gentle exercises in your seat to improve your circulation. ### How to get through airport security fast when flying to Sion? > - Airport security personnel first need to establish that you have a valid ID and boarding pass before you're allowed to proceed any further. Have them ready for inspection. > - After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Items such as your jacket, belt and headphones will be required to go through the machine. > - For just a few minutes, you'll have to unplug from technology. Your laptop, phone and any other electronics will need to go through the scanner. > - Any liquids or gels, such as toothpaste or perfume, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag. > - Choosing your footwear wisely can save you several precious minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on sneakers are usually not. > - Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked luggage. They won't be allowed on board and will be confiscated. __Flights to Sion information__ | Destination airport | Sion | | ----------------------------- | ---- | | Destination airport IATA code | SIR | ## Explore a world of travel with Expedia -
