How to survive the flight to Brussels?
If you're poorly prepared, air travel can be challenging. But don't hit the panic button just yet. Follow these helpful hints and enjoy a worry-free start to your time in Brussels.What to pack in your hand luggage:

  • Firstly, and most importantly, pack in your passport, official ID, credit cards and medications. Next, you'll want some in-flight entertainment to while away the time. A thrilling book and a tablet crammed with your favourite shows are some fantastic options. If you intend to take a quick nap, a comfy neck pillow and some noise-cancelling headphones will also come in handy. Finally, leave space for a toothbrush and some deodorant to ensure you step off the plane looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general rule to follow is nothing flammable, sharp or explosive. This includes things like tools, metal cutlery, spray paint and flares. Sports equipment like hockey sticks, and objects that could harm passengers, such as firearms and swords, can't come on board with you either.

What to wear on a flight:

  • The answer to a comfortable flight is as simple as your choice of clothes. Prepare for temperature changes by layering up. This will keep you nice and warm if the cabin starts to cool down. Shoes like stilettos, flip flops and lace-up boots are best left in your checked suitcase. Even though they may be your favourites, go for flat, closed-toed footwear like sneakers. Your feet will appreciate it.
  • The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-distance flights. But the good news is there are numerous ways to significantly reduce the risk of developing it. Keep your fluids up, get up and walk around the cabin wherever possible and wear compression socks to help improve your circulation.

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

  • Be sure to keep your travel documents and ID close by. They're the first things you'll be asked to present to security.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other items in your pocket, like coins, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn.
  • For just a few minutes, you'll need to unplug from technology. Your phone, laptop and any other electronic devices must also be sent through the scanner.
  • Any gels or liquids, such as perfume or toothpaste, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • Choosing your footwear wisely can save you several precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Airlines will not allow any sharp items or pocket knives in your carry-on baggage. If you must bring these kinds of items, pack them safely in your checked luggage.
