Do you have any tips for my flight to Onyang?
We've got the lowdown on how to make your journey a stress-free experience. Follow our tips and you'll be breezing through the airport and having a ball in Onyang in no time at all. What to pack in your hand luggage:

  • The secret to having an amazing flight experience is to pack ahead. First up, the essentials: passport, boarding pass, bank cards and any vital medications. Next, take on board items that'll help while away those hours, like some electronic devices or a juicy novel. It's also wise to bring your chargers, a quality neck pillow and a pair of noise-canceling headphones. Last but not least, be sure to squeeze in toiletry items like a toothbrush, deodorant and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by security. Sharp or pointed objects, like your trusty pocket knife, and dangerous products which are flammable or explosive, such as flares, bleaching agents and strong acids, are also prohibited.

What to wear on a flight:

  • Comfort should be your highest priority when choosing what to wear on your flight. Loose clothing is a wise option, as are flat, enclosed shoes.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Onyang?
As savvy travelers know, the secret is to be prepared before you get to airport security. That way, you'll be hopping onto that plane to Onyang in the blink of an eye. Follow these tips and get your vacation off to a fantastic start:

  • First things first. Your travel documents and passport will need to be inspected by airport security. Keep them within easy reach so you don't have to dig around for them.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like laptops and phones will also have to go on a tray for inspection. Don't worry though, you'll be back online in no time.
  • Want to bring along your favorite hand and nail cream? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, it's OK to bring with you in your carry-on baggage.
  • Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when going through security. Big boots and heavier-style shoes are often subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked baggage. They won't be allowed on board.
