Do you have any tips for my flight to Twin Peaks?
Wherever you're jetting in from, flying can be a pleasurable experience if you've prepared well enough. We've compiled a list of handy tips that will help get your Twin Peaks escape started on the right foot. What to pack in your hand luggage:

  • The secret to having a stress-free travel experience is to be prepared. Start with the essentials: passport, official ID, credit cards and medications. Next, bring on board items that'll help keep you entertained, like some electronic gadgets or a good book. It's also a wise idea to bring your chargers, a neck pillow and a pair of earphones. Finally, be sure to toss in toiletry items like a toothbrush, deodorant and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes tools, metal cutlery, fuels and bleaching agents. Sporting equipment like bows and arrows, and objects that could harm other people, such as swords and guns, aren't allowed in the cabin either.

What to wear on a flight:

  • Your priority is to feel as comfortable as possible. Go for a pair of slip-on shoes, dress in loose, natural fibers and don't forget to take a sweater in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Twin Peaks?
Being prepared before your flight will help make your trip to Twin Peaks a pleasure. Check out our handy tips for a stress-free journey through security:

  • Have your passport and boarding pass someplace easily accessible. They'll be the first things you'll be asked to present to security.
  • Next up, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items like your jacket, belt and earphones need to go through the machine.
  • For just a few moments, you'll need to unplug from technology. Your phone, tablet and any other electronic gadgets also need to go through the scanner.
  • Can't travel without your favourite hand and nail cream? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can bring it with you in your carry-on baggage.
  • Lightweight sneakers are a good footwear choice as you're less likely to have to remove them when going through security. Big boots and other bulky shoes are usually subjected to additional screening.
  • Sharp items like knives are not allowed on board. They'll be seized at security, so pack them safely away in your checked luggage.
