Do you have any tips for my flight to Si Wilai?
Wherever you're coming from, flying can be an enjoyable experience if you've prepared well enough. We've put together a list of handy hints that will help get your Si Wilai escape started on the right note. What to pack in your hand luggage:

  • The secret to having a stress-free travel experience is to pack ahead. First up, the essentials: passport, travel documents, cash and important medications. Next, bring items that'll help pass the time, like your laptop or a thrilling book. It's also wise to bring your chargers, a neck pillow and a pair of earphones. Last but not least, be sure to pop in toiletries like a toothbrush, lip balm and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hairspray in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your Swiss Army knife, and products which are explosive or flammable, such as spray paint, flares and fuels, are also not allowed.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for temperature changes in the cabin by wearing layers, and wear flat, closed-toe footwear like sneakers.
  • Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Si Wilai?
As seasoned travellers know, the secret is to be organised before you reach the airport security gate. That way, you'll be hopping onto that plane to Si Wilai in a flash. Follow these tips and get your trip off to a terrific start:

  • Be sure to keep your travel documents and passport within easy reach. They're the first things you'll be asked to present to security.
  • Next up, both you and your carry-on luggage must be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Personal belongings such as your belt, jacket and headphones will be required to go through the machine.
  • All your electronic devices, including your phone and laptop, must also be separately scanned.
  • Remove all liquids and gels from your carry-on bag. They often need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • There's a possibility that you'll need to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Airlines won't allow any sharp or pointed objects in the cabin. If you need to bring these kinds of items, pack them in your checked luggage.
