Do you have any tips for my flight to Waterloo?
We've got the lowdown on how to make your journey an enjoyable experience. Follow our insider tips and you'll be hightailing it through the airport and having a ball in Waterloo in no time flat. What to pack in your hand luggage:

  • The secret to having a stress-free flight experience is to pack in advance. First up, the essentials: passport, travel docs, credit cards and vital medications. Next, take on board items that'll help pass the time, like some electronic gadgets or a juicy novel. It's also a wise idea to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, be sure to toss in toiletry items like a toothbrush, lip balm and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a knife or scissors) lurking in your hand luggage. Other prohibited items include explosive or flammable goods, such as fuel and fireworks, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of an airplane are no place for a fashion parade. Layer up with comfortable clothing and choose shoes that are enclosed, flat and easy to pull on and off.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-distance flights. Lower your risks by staying hydrated, keeping your lower limbs moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Waterloo?
A little pre-planning before you arrive at the airport will help make your trip to Waterloo easy and painless. Below are some handy tips for a swift journey through security:

  • Keep your ID and boarding pass someplace easily accessible. They're the first things you'll be asked for by security.
  • Your coat, belt, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn.
  • Electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online in no time.
  • Travelling with your favourite hand and nail cream? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're allowed to bring it with you in your carry-on luggage.
  • Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when passing through security. Hiking boots and other bulky shoes are often subjected to extra screening.
  • Airlines will not allow any pocket knives or other sharp items in your hand luggage. If you must bring these kinds of items, pack them safely in your checked luggage.
