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-canceling 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 milliliters).

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.

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.
• Traveling with your favorite hand and nail cream? As long as it's in a container no larger than 3.4 ounces (100 milliliters) 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.
