Do you have any tips for my flight to Siwan?
- Flying can be a stress-free experience if you carry the right gear. Firstly, you'll want a few basic toiletries, such as deodorant, toothpaste and a toothbrush, a clean set of clothes and a few magazines. Next, make room in your bag for your phone, tablet and chargers, medications and maybe a blow-up neck pillow as well. Lastly, and most importantly, remember to bring your passport, travel documents and your bank cards.
- Put all your full-sized bottles of shampoo and hairspray in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Pointed or sharp objects, like your treasured Swiss Army knife, and products which are explosive or flammable, such as aerosol cans, spray paint and poisons, are also not allowed.
- The aisles of an airplane aren't the place for a fashion parade. Layer your clothing and opt for shoes that are roomy, flat and easy to pull on and off.
- The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-distance flights. Reduce the risks by drinking water, keeping your legs and ankles moving and wearing compression socks to help your circulation.
How to get through airport security fast when flying to Siwan?
- Keep your travel documents and ID handy. They'll be the first things you'll be asked to present to security.
- The X-ray machine comes next. Remove anything metal on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
- All your electronic gadgets, including your phone and tablet, are also required to be scanned.
- Any liquids or gels, such as shampoo or hand cream, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
- Choosing your footwear wisely can save you a few precious minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Lightweight sneakers usually aren't.
- Sharp or pointed items are not allowed in the cabin. They'll be seized at security, so pack them in your checked baggage.
