First of all you'll need basic toiletries, such as a toothbrush and lip balm, a spare pair of socks and a good book.

Sharp or pointed objects, like your Swiss Army knife, and dangerous products which are flammable or explosive, such as spray paint, flares and fuels, are also prohibited. > > > What to wear on a flight: > > > - Comfort should be your priority when deciding what to wear during your flight. Loose clothing is a smart option, as are flat, slightly roomy shoes. > - Most travellers have heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. To reduce your risk on board, drink lots of water, consider wearing compression socks or tights and keep your legs and feet moving. ### How to get through airport security fast when flying to De Smet? > - Security personnel first need to establish that you have a valid passport and boarding pass before anything else. Have them close by, ready for inspection. > - After that, both you and your carry-on luggage must be X-rayed. To speed things up, take off anything that might trigger the alarms. Items such as your coat, belt and earphones will be required to go through the machine. > - For just a few moments, you'll have to unplug from the digital world.

They must also all fit inside a quart-size (one litre), clear zip-lock bag. > - Slip-on shoes are a sensible footwear choice as you're less likely to be required to remove them when passing through security. Big boots and other heavy-style shoes are usually subjected to extra screening. > - Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase.
