Do you have any tips for my flight to Sum Sao?
Depending on where you're coming from, your flight to Sum Sao could be completely painless or it could go on forever. We've pulled together some handy travel tips that will help you start your next great escape on the right foot. What to pack in your hand luggage:
  • The trick to having a great travel experience is to pack in advance. Start with the essentials: passport, travel docs, cash and daily medications. Next, take on board items that'll help pass the time, like some electronic gadgets or a few magazines. It's also wise to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to toss in toiletries like a toothbrush, deodorant and a clean T-shirt.
Do not pack the following items in your hand luggage:
  • Check carefully that you don't have sharp objects (like a pocket knife) hiding in the bottom of your hand luggage. Other restricted items include explosive or flammable products, like aerosols and matches, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your aim is to feel as comfortable as possible. Pick a pair of slip-on shoes, dress in loose, natural-fibre clothing and remember to take a jacket 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. Make a point of walking around the cabin or do some gentle exercises in your seat to promote better circulation.
How to get through airport security fast when flying to Sum Sao?
The simple answer is — be prepared. We've put together some useful tips for a stress-free trip through airport security. Look out Sum Sao, here you come:
  • First things first. Your boarding pass and travel ID will need to be presented to security personnel. Have them easily accessible so you don't hold up the line.
  • After that, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items like your belt, jacket and headphones need to go through the machine.
  • All your electronic gadgets, including your tablet and phone, are also required to be scanned.
  • Any gels or liquids, such as shampoo or hairspray, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • There's a possibility that you'll need to remove your shoes for scanning, so wearing slip-on shoes 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, put them in your checked luggage. They won't be allowed on board and will be confiscated.
