First things first, you'll need basic toiletries, such as toothpaste, a toothbrush and some deodorant, a clean set of clothes and a few magazines. Secondly, make room in your bag for your mobile phone, a charger, any vital medications and perhaps a proper neck pillow too. Lastly, and most importantly, remember to take your passport, travel docs and some money. > > > Do not pack the following items in your hand luggage: > > > - Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like your trusty Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosol cans, flares and poisons, are also restricted. > > > What to wear on a flight: > > > - The aisles of a plane are no place for a fashion parade. Dress in comfortable layers and opt for shoes that are enclosed, flat and easy to pull on and off. > - Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To reduce your risk on board, drink lots of water, consider wearing compression socks or tights and keep your feet and legs moving. ### How to get through airport security fast when flying to St. Charles? > - Keep your ID and travel documents at hand.
