Cheap Flights to Brussels from HK$4,213

We've got the lowdown on how to make your flight an enjoyable experience. Follow our insider tips and you'll be cruising through airport security and seeing the best of Brussels in no time at all. What to pack in your hand luggage:

• The trick to having a pain-free flight experience is to plan ahead. So, let's start with the basics: passport, travel docs, cash and important medications. Next, take on board items that'll help keep you busy, like your laptop or a thrilling book. It's also a wise idea to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to chuck in toiletry items like a toothbrush, deodorant and a fresh 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 luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like a pocket knife, and products which are explosive or flammable, such as aerosol cans, spray paint and gasoline, are also not allowed.

What to wear on a flight:

• Choose comfort over style. Prepare for changes in temperature by layering up, and pick flat, easy-to-remove shoes like slip-ons.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged 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.

It's easy — be prepared. We've put together some top tips for an easy trip through airport security. Watch out Brussels, here you come:

• Be sure to have your ID and travel documents within close reach. They're the first things you'll be asked to present to airport security.
• Time to strip down. Well kind of. 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 easier by removing them before your turn.
• For just a few moments, you'll have to unplug from technology. Your phone, laptop and any other electronic devices will need to go through the scanner.
• Can't travel without your favourite hand cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can bring it with you in your carry-on bag.
• Slip-on shoes are a good footwear choice as you're less likely to have to remove them when passing through security. Big boots and other heavy shoes are usually subjected to additional screening.
• Sharp items can't be taken on board. They'll be confiscated at security, so pack them in your checked baggage.
