Do you have any tips for my flight to Swiss?
We've pulled together all the info you need to make your flight a pleasant experience. Follow our top tips and you'll be hightailing it through the airport and enjoying Swiss before you know it. What to pack in your hand luggage:
  • Air travel can be a comfortable experience if you've got all the right gear. First things first, you'll need basic toiletries, such as deodorant, toothpaste and a toothbrush, a spare change of clothes and a good read. Secondly, find a spot in your carry-on bag for your mobile phone, a charger, any vital medications and maybe a comfy neck pillow too. Last, but definitely not least, be sure to take your passport, travel papers and your credit cards.
Do not pack the following items in your hand luggage:
  • Check carefully that you don't have sharp objects (like a knife or scissors) lurking in your carry-on luggage. Other prohibited items include explosive or flammable goods, such as fuel and matches, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Comfort should be your top priority when choosing what to wear on board. Loose, breathable clothing is a sensible choice, as are flat, slightly roomy shoes.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-haul flights. Reduce the risks by drinking water, keeping your legs and ankles moving and wearing compression tights or socks.
How to get through airport security fast when flying to Swiss?
The trick is to be organised before you get to the security gate. That way, you'll be boarding that plane to Swiss in the blink of an eye. Follow these tips and get your holiday off to a fantastic start:
  • Airport security personnel first need to verify that you have a valid passport and boarding pass before anything else. Have them ready for inspection.
  • After that, both you and your hand luggage will be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items such as your belt, jacket and earphones will be required to go through the machine.
  • For just a few minutes, you'll have to unplug from technology. Your phone, laptop and any other electronic gadgets also need to go through the scanner.
  • Any liquids or gels, such as lip balm or cologne, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • There's a good chance you'll need to remove your shoes for scanning, so wearing lightweight sneakers is always a wise idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed on board and will be confiscated.
