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. ### How to get through airport security fast when flying to Brussels? > - 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. __Flights to Brussels information__ | Destination airport | Lambert-St. Louis Intl. | | ----------------------------- | ----------------------- | | Destination airport IATA code | STL | | Destination city name | St. Louis | | Return price | £85 | ## Trending flights to Brussels Prices were available within the past 7 days and start at £43 for one-way flights and £85 for round trip, for the period specified.
